About the Special Issue

Nowadays, realizing the biological, environmental, and chemical world is progressively important for numerous research areas. Biosensors are devices including a biological and physicochemical segment to notice an analyte by producing a signal which can be measured. Biosensors are integrated receptor–transducer tools that can deliver selective quantitative/semiquantitative analytical data using a biological recognition component. A specific biosensor usually includes a biosensing component and a transducer. The sensitive biological element, e.g., tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc., is a biologically derived material or biomimetic component that interacts with, binds with, or recognizes the analyte under study. Biologically sensitive elements can also be created by biological engineering. It has various biological applications and is used for the detection of several components such as pollutants, microbial load, metabolites, control parameters, and various other substances. It also has immense applications in the food industry, clinical diagnostics, and various other areas where reliable and precise analyses are required. During the last few decades, numerous biosensing elements and devices have been developed. Biosensors have numerous applications in various fields such as bio-monitoring of pollutants, disease diagnostics, the food industry, the medical field, the marine sector, etc., and they provide better stability and sensitivity as compared with traditional methods. etc. The most common types of biosensors are electrochemical biosensors, Optical biosensors, Biological biosensors, Electronic nose devices, DNA biosensors, Graphene-based biosensors, Nanomaterials based biosensors, Enzyme-based, Tissue-based, Immunosensors, Thermal and Piezoelectric biosensors, and so on. The goal of this special issue is to give a platform to the research work that centers on all aspects of biosensor applications.
