Special Issue "World of Biosensing"
Deadline for manuscript submissions: 31 December 2020.
Interests: enzymatic biosensors for water- and airborne organic pollutants; cytotoxins for eradication of bacteria
Interests: enzyme- and cell-based electrochemical biosensors for analysis of food and environmental samples
It is hard to imagine how humans managed to cope with multiple everyday problems in the past without biosensors—devices based on selective biorecognition enabling sensitive monitoring and measurement of target compounds by converting biological responses into electric or optical signals. Electrochemical biosensors based on amperometric, potentiometric, and impedance measurement, optical biosensors using surface plasmon resonance, optical fibers and piezoelectric biosensors based on microcantilevers are currently employed for detecting these signals.
Tissues, cells, organelles, biomolecules, and their complexes are used as biorecognition elements in biosensors for highly-selective analysis of practically important analytes, including organic and inorganic compounds, toxins, and microorganisms. The target analyte is usually either a substrate or an inhibitor of cell metabolism.
Enzyme biosensors are the most widely used devices, and some are produced commercially. The world biosensors market is expected to reach $22.68 billion by 2020, with an annual growth of 10% from 2014 to 2020. Cell-based biosensors consist of a transducer in conjunction with immobilized microbial cells, which are low-cost substitutes for enzymes.
Combining novel bio- and nanotechnologies is creating prospects for production of new materials for biosensors with advanced characteristics. Nanomaterials can be used as carriers for bioelements and as artificial enzymes (nanozymes).
In less than 60 years, biosensors have caused revolutionary changes in analytical chemistry, medicine, environmental studies, security, food industry including winemaking, by replacing complex and tedious traditional analyses with fast, selective, and accurate measurements of responses to specific analytes.

Title: Recent development of morphology controlled conducting polymer nanomaterial-based biosensor
Author: Prof. Dr. Junseop Lee; [email protected]
Abstract: Biosensors are being studied to detect certain biological target analyte at low concentrations. As a sensing transducer, conducting polymer nanomaterials are conducted owing to their inherent properties such as small dimensions, high surface to volume ratio, and amplified sensitivity. However, conventional conducting polymer nanomaterials have inhibitions that limit the amount and uniformity of the binding biomolecules into the structure. Herein, we illustrate a brief overview of the recent progress in the development of morphology controlled conducting polymer based biosensors. Particularly, we focus our discussions on various dimensional (0D, 1D, 2D, and 3D) hetero-nanostructure of conducting polymers to solve essential problems that are highly sensitive, fast charge transfer, working at low temperature, and cycle stability to target analyte.
Title: Recent advance in the fabrication of colorimetric biosensors for toxicity detection in environmental science
Author: Prof. Dr. Gang Wei; [email protected]
Abstract: Colorimetric biosensors exhibited great potential for the detection of metallic ions, organic dyes, drugs, pesticides and other toxic pollutants due to their easy fabrication, quick detection, high sensitivity, and naked-eye sensing. In this work, we present recent advance in the fabrication and environmental science application of biosensor platforms based on various functional nanomaterials including gold nanoparticles, silver nanoparticles, quantum dots, graphene, MXenes, and others. The strategies for the constructing high-performance biosensing systems for toxicity detection are introduced and discussed in detail. The advantages and disadvantages of the colorimetric biosensors are compared with other biosensor techniques. It is expected this work will be valuable for readers to understand the fabrication and sensing mechanisms of various colorimetric biosensors and promote their development in environmental science, food science, and bioanalysis.
