Preparation and application of chitosan-based fluorescent probes

Abstract

Biomass materials have abundant natural resources, renewability and good biochemical compatibility, so biomass-based fluorescent materials prepared from biomass materials have gradually become a research hotspot. In particular, the low cost and environmentally friendly properties of chitosan have been widely used in the field of functional materials. Chitosan-based functional materials have attracted extensive attention in the detection and removal of organic and inorganic pollutants. They have been widely used in biological imaging, environmental detection, drug carriers and other fields. This paper reviews the preparation and application of chitosan-based fluorescent probes, including chitosan-derived fluorescent probe materials and chitosan-based carbon quantum dots. At the same time, it focuses on the application research of chitosan-based carbon quantum dots in the fields of environmental detection, cell imaging, drug carriers, photocatalysis, etc. In addition, it provides new ideas and application prospects for the development and application of chitosan-based fluorescent materials in the future.
