Abstract
Various kinds of biosensors such as immunosensors, DNA biosensors, and enzyme-based, tissue-based, thermal, and piezoelectric biosensors have been studied by many authors and applied in biological and environmental fields for the detection of various pollutants. In this chapter, chitosan-based biosensors have been discussed with good sensitivity and selectivity for the determination of various analytes such as glucose, cholesterol, Hb, H2O2, small biomolecules, DNA, heavy metal ions, and poisonous gaseous molecules. Different physicochemical parameters such as pH, time, and concentration of analyte have been explained, which have great impact on the working of biosensor. Analytical parameters such as linear range, detection limit, accuracy, and precision have been summarized. Chitosan-based biosensor might open up newer possibilities as a biosensor due to their promising advantages, namely, easy preparation, low cost, and good conductive sensitivity.
