The work aims to provide the summary of research on fluorescent hydrogels in anti-counterfeiting and explore their potential of being used as a new anti-counterfeiting device.The fluorescent hydrogels were classified based on the different types of fluorescent emission sources and the progress of research was reviewed in three areas:preparation,functional response mechanism,and application.Relevant literature was reviewed to provide an up-to-date overview of the latest progress in information anti-counterfeiting.Fluorescent hydrogels could be classified into 6 categories based on the introduced fluorescent emission sources,namely carbon points,lanthanides,organic fluorescent agents,aggregation-induced dyes,multiple emission sources,and other types.By adjusting the size and color changes,the encryption/decryption process could be achieved,thus enhancing the level of information security.In conclusion,fluorescent hydrogel is a functional material with unique stimulus response,which has great significance in information security.
