Hydrogels for Chemical Sensing and Biosensing

The development and synthesis of hydrogels for chemical and biosensing are of great value. Hydrogels can be tailored to its own physical structure, chemical properties, biocompatibility, and sensitivity to external stimuli when being used in a specific environment. Herein, hydrogels and their applications in chemical and biosensing are mainly covered. In particular, it is focused on the manner in which hydrogels serve as sensing materials to a specific analyte. Different types of responsive hydrogels are hence introduced and summarized. Researchers can modify different chemical groups on the skeleton of the hydrogels, which make them as good chemical and biosensing materials. Hydrogels have great application potential for chemical and biosensing in the biomedical field and some emerging fields, such as wearable devices. Hydrogels have vast applications in chemical and biosensing. Compounds with specific functional groups are selected to prepare them as responsive hydrogels. They offer high sensitivity and selectivity in various chemical sensing applications, including electrochemical sensing. In the field of biosensing, they may be used in wearable devices, human detection, and drug delivery, opening up new possibilities for life science research.image
