Аннотация: The possibility of the development of the solid phase bioluminescent biotest using aerial mycelium of luminous fungi was investigated. Effect of organic and inorganic toxic compounds (TC) at concentrations from 10 -6 to 1 mg/ml on luminescence of aerial mycelia of four species of luminous fungi-Armillaria borealis (Culture Collection of the Institute of Forest, Siberian Branch, Russian Academy of Sciences), A. mellea, A. gallica, and Lampteromyces japonicus (Fungi Collection of the Botanical Institute, Russian Academy of Sciences)-has been studied. Culture of A. mellea was shown to be most sensitive to solutions of the model TC. It was demonstrated that the sensitivity of the luminous fungi is comparable with the sensitivity of the bacteria that are used for environmental monitoring. Use of the aerial mycelium of luminous fungi on the solid support as a test object is a promising approach in biotesting for the development of continuous biosensors for air monitoring.

Аннотация: This review examines the general principles of bioluminescent enzymatic toxicity bioassays and describes the applications of these methods and the implementation in commercial biosensors. Bioluminescent enzyme system technology (BEST) has been proposed in the bacterial coupled enzyme system, wherein NADH: FMN-oxidoreductase-luciferase substitutes for living organisms. BEST was introduced to facilitate and accelerate the development of cost-competitive enzymatic systems for use in biosensors for medical, environmental, and industrial applications. For widespread use of BEST, the multicomponent reagent "Enzymolum'' has been developed, which contains the bacterial luciferase, NADH: FMN-oxidoreductase, and their substrates, co-immobilized in starch or gelatin gel. Enzymolum is the central part of Portable Laboratory for Toxicity Detection (PLTD), which consists of a biodetector module, a sampling module, a sample preparation module, and a reagent module. PLTD instantly signals chemical-biological hazards and allows us to detect a wide range of toxic substances. Enzymolum can be integrated as a biological module into the portable biodetector-biosensor originally constructed for personal use. Based on the example of Enzymolum and the algorithm for creating new enzyme biotests with tailored characteristics, a new approach was demonstrated in biotechnological design and construction. The examples of biotechnological design of various bioluminescent methods for ecological monitoring were provided. Possible applications of enzyme bioassays are seen in the examples for medical diagnostics, assessment of the effect of physical load on sportsmen, analysis of food additives, and in practical courses for higher educational institutions and schools. The advantages of enzymatic assays are their rapidity (the period of time required does not exceed 3-5 min), high sensitivity, simplicity and safety of procedure, and possibility of automation of ecological monitoring; the required luminometer is easily available.

Аннотация: The biomodule of bioluminescent biosensor based on a coupled enzyme system NADH:FMN-oxidoreductase and luciferase, co-immobilized with substrates in dried starch or gelatin gels, has been developed. We studied the impact of several stabilizers - dithiothreitol (DTT), bovine serum albumin (BSA) and mercaptoethanol (ME) on the biomodule's activity, storage stability and sensitivity to toxic substances. The inclusion of stabilizers increases the activity of the biological module by more than 150%. To achieve the combination of high activity, prolonged storage time and acute sensitivity to toxic substances within maximum permissible concentration we used starch gel as a carrier adding 100 ?M DTT to the immobilized preparation. The gelatin-based biological module had greater storage stability than the starch-based one but demonstrated less sensitivity to toxic substances. © 2015 Elsevier B.V. All rights reserved.

Аннотация: Optically enhanced biosensing strategies are prerequisites for developing miniature and highly sensitive multiplexed analytical platforms. Such smart biosensing systems are highly promising for use in the fields of biomedicine and environmental monitoring. Optical signal enhancement during bioassays is attributed to the complex opto-electronic interactions of incoming photonic signals at the nanomaterial interface. Research on the use of metals other than gold and silver for such purposes tends to extend the spectral window to observe luminescence enhancement effects. Such manifold increase in luminescence may be explained by the principles of plasmon coupling, directional emission led high collection efficiency, Rayleigh scattering and related opto-electronic events. The present review begins with a mechanistic description of important phenomena associated with metal-induced luminescence enhancement, particularly focusing on the origin of metal-enhanced luminescence. This review further analyses the hybrid nanostructure capabilities responsible for maintaining unique opto-electronic properties during bio-functionalisation. Current research trends in this area, future scope of this field for designing useful bioassays and concluding remarks are then discussed. (C) 2017 Elsevier B.V. All rights reserved.

Аннотация: Bioluminescence of isolated enzymes is a perspective phenomenon for biosensors development due to simplicity of registration of a physiological parameter - light intensity. Enzyme-based bioluminescent assay is widely used to evaluate a decrease in biochemical toxicities. Also the enzyme-based assay is used for the direct biochemical monitoring of oxidative toxicity. This work considers antioxidant properties of fullerenols, water-soluble polyhydroxylated derivatives of fullerenes and perspective pharmaceutical agents, in solutions of model inorganic and organic toxicants of oxidative type K-3[Fe(CN)(6)] and 1,4-benzoquinone. Two fullerenol preparations were used: C60O2-4(OH)(20-24) and mixture of two types of fullerenols C60O2-4(OH)(20-24)+C70O2-4(OH)(20-24). The enzyme-based assays showed the peculiarities of the detoxification processes: ultralow concentrations of fullerenols were active (ca 10(-17)-10(-5)g/L); no monotonic dependence of detoxification efficiency on fullerenol concentrations was observed, and detoxification of organic oxidizer solutions was more effective than that of the inorganic oxidizer. The antioxidant effects of highly diluted fullerenol solutions were attributed to hormesis phenomenon; the detoxification was concerned with stimulation of adaptive cellular response under low-dose exposures.

Аннотация: A number of approaches have been proposed and tested to transfer enzymatic reactions into the functional elements of microfluidic chips on the example of the bienzyme bioluminescent reaction involving NAD(P)H:FMN-oxidoreductase and luciferase. Measurement of the catalytic activity of these enzymes (under the influence of pollutants) is the basis of enzymatic bioassay of various liquids. It was found that all of the components of the reaction must be placed in the same cell of the chip to improve the reproducibility of the measurements. The use of starch gel as a carrier for immobilization and gelatin as a scaffold in the reactor of the chip enables the preservation of enzyme activity in the course of sealing the chip at room temperature. It is shown that the components of the reaction should be vigorously stirred in a microfluidic chip reactor to improve the efficiency of the analysis. As a result of the studies, a prototype of microfluidic chip based on the enzymatic bioluminescent reaction is proposed. It is characterized by a detection limit of copper sulfate of 3 mu M that corresponds to the sensitivity of traditional lux-biosensors based on living cells. The analysis time is reduced to 1 min, and the analysis can be performed by individuals without special laboratory skills.

Аннотация: In the present study, we demonstrate the use of a disposable luciferase-based microfluidic bioassay chip for environmental monitoring and methods for fabrication. The designed microfluidic system includes a chamber with immobilized enzymes of bioluminescent bacteria Photobacterium leiognathi and Vibrio fischeri and their substrates, which dissolve after the introduction of the water sample and thus activate bioluminescent reactions. Limits of detection for copper (II) sulfate, 1,3-dihydroxybenzene and 1,4-benzoquinone for the proposed microfluidic biosensor measured 3 ?M, 15 mM, and 2 ?M respectively, and these values are higher or close to the level of conventional environmental biosensors based on lyophilized bacteria. Approaches for entrapment of enzymes on poly(methyl methacrylate) (PMMA) plates using a gelatin scaffold and solvent bonding of PMMA chip plates under room temperature were suggested. The proposed microfluidic system may be used with some available luminometers and future portable luminescence readers. © 2018 John Wiley & Sons, Ltd.

Аннотация: Enzymatic luminescent systems are a promising tool for rapid detection of heavy metals ions for water quality assessment. Nevertheless, their widespread use is limited by the lack of test procedure automation and available sensitive handheld luminometers. Herein we describe integration of disposable microfluidic chips for bioluminescent enzyme-inhibition based assay with a handheld luminometer, which detection system is based on a thermally stabilized silicon photomultiplier (SiPM). Microfluidic chips were made of poly(methyl methacrylate) by micro-milling method and sealed using a solvent bonding technique. The composition of the bioluminescent system in microfluidic chip was optimized to achieve higher luminescence intensity and storage time. Results indicate that developed device provided comparable sensitivity with bench-scale PMT-based commercial luminometers. Limit of detection for copper (II) sulfate reached 2.5 mg/L for developed biosensor. Hereby we proved the concept of handheld enzymatic optical biosensors with disposable chips for bioassay. The proposed biosensor can be used as an early warning field-deployable system for rapid detection of heavy metals salts and other toxic chemicals, which affect bioluminescent signal of enzymatic reaction.

Аннотация: DNA probe-based biosensors have been widely developed for detecting a range of analytes. However, the DNA probe-based sensors suffer from many problems, such as long hybridization time, background electrical noise, and relatively poor specificity. In this paper, we report the ultrasensitive detection for RNA by graphene field effect transistor (G-FET) biosensor using PNA and DNA probes. The limit of detection (LOD) of the PNA probe-modified G-FET sensor is down to 0.1 aM, which is three orders of magnitude lower than that of DNA probe-modified G-FET sensor. We demonstrate that both PNA and DNA probe-modified G-FET have great potential in quantitative detection of RNA. A good linear electrical response to RNA concentrations is obtained in a broad range from 0.1 aM to 1 pM for PNA probe-modified G-FET and from 100 aM to 1 pM for DNA probe-modified G-FET, respectively. The PNA probe-modified G-FET sensors significantly reduce the detection time compared to DNA probe-modified G-FET sensors. Moreover, the electrical response of PNA probe-modified G-FET biosensor to non-complementary RNA is negligible, showing high specificity for RNA detection. What's more, the G-FET sensor was also used to detect RNA in human serum, making it a promising way for future detection of RNA in biomedical research and early clinical diagnosis. © 2020 Elsevier B.V.

Graphene field effect transistor -- PNA probe -- RNA detection
Аннотация: DNA probe-based biosensors have been widely developed for detecting a range of analytes. However, the DNA probe-based sensors suffer from many problems, such as long hybridization time, background electrical noise, and relatively poor specificity. In this paper, we report the ultrasensitive detection for RNA by graphene field effect transistor (G-FET) biosensor using PNA and DNA probes. The limit of detection (LOD) of the PNA probe modified G-FET sensor is down to 0.1 aM, which is three orders of magnitude lower than that of DNA probe modified G-FET sensor. We demonstrate that both PNA and DNA probe-modified G-FET have great potential in quantitative detection of RNA. A good linear electrical response to RNA concentrations is obtained in a broad range from 0.1 aM to 1 pM for PNA probe-modified G-FET and from 100 aM to 1 pM for DNA probe-modified GFET, respectively. The PNA probe-modified G-FET sensors significantly reduce the detection time compared to DNA probe-modified G-FET sensors. Moreover, the electrical response of PNA probe-modified G-FET biosensor to non-complementary RNA is negligible, showing high specificity for RNA detection. What's more, the G-FET sensor was also used to detect RNA in human serum, making it a promising way for future detection of RNA in biomedical research and early clinical diagnosis.

Аннотация: We synthesized large-area single-crystal graphene sheets to use them in biosensors based on field-effect transistors (FET) for quantitative analysis of interaction kinetics and affinity between the imatinib drug and its target protein kinase Abl1. The G-FET biosensor showed an excellent performance and recognized imatinib at as low as 15.5 fM. The biosensor also showed a linear response to the logarithm of imatinib concentration in the 0.1 pM-10 ?M range. This graphene-based FET biosensor (G-FET) was also applied to quantify Abl1 Y253 F mutation and Abl1 dependency on Mg2+ to bind to imatinib in real-time. Results demonstrated in this work clearly showed that the novel G-FET biosensors are very promising to analyze interactions between proteins and low molecular weight drugs. © 2020 Elsevier B.V.

Аннотация: Upcoming professional sports authorities seek rapid noninvasive biosensing tools for regular monitoring of athletes' physiological states. The analysis of saliva through luminescence-based biosensors has been perceived as a suitable candidate for such purposes. The present study reports a qualitative bioluminescence assay based on a coupled enzyme system that consists of bacterial luciferase (BLuc) and nicotinamide adenine dinucleotide (NADH):flavin mononucleotide (FMN) oxidoreductase (Red), BLuc-Red, for the express diagnostics of athletes' stress levels before and after physical exertion. The volunteers who participated in the study were grouped as freestyle wrestlers and students who adapted to different levels of physical activities. Under physical exertion modelling conditions, the influence of participant saliva on BLuc-Red catalyzed light emission was investigated. Results showed a significant increase in residual luminescence (I-exp, mean maximum bioluminescence intensity of the experimental measurement (I-exp); I-c, luminescence intensity in control; I-exp/I-c, %) values for participants in the wrestler group while a decrease in the student group (P < 0.05). Such contrasting residual luminescence values in both groups were found to be dependent on the catalase activity of saliva. The proposed bioluminescence assay can be utilized as a potential nonspecific biosensing tool for determining the physical state of athletes under high loads.
