Adlayer structure innovation and film-based fluorescent sensors

Film-based Fluorescent Sensors (FFSs) represent a crucial option in the realm of developing highperformance sensors for dangerous, toxic, harmful chemicals, biological substances, and radioactive materials. By focusing on aspects such as mass transfer, energy transfer, microenvironment effects, and the utilization rate of sensing units that significantly impact the performance of FFSs, we elaborate on the pivotal role of adlayer structure innovation in the development of FFSs. This encompasses key areas like sensing units design and synthesis, modulation of excited state processes, and optimization of adlayer structures. Furthermore, we delve into innovations in sensor hardware structure and advancements in detection equipment. Drawing from these discussions, we explore the development prospects and major challenges facing FFSs
