摘　　要：Dopamine,a pivotal excitatory neurotransmitter,plays a crucial role in metabolic,cardiovascular,renal,central nervous,and endocrine systems.Abnormal dopamine within the human body can cause various diseases.Therefore,the precise quantification of dopamine levels,both in vivo and in vitro,holds paramount significance for clinical applications and physiological investigations.Carbon dots(CDs)exhibit a plethora of remarkable properties,including a substantial specific surface area,robust electrical conductivity,commendable biocompatibility,minimal toxicity,and high photostability.Considering these unique characteristics,CDs demonstrate substantial potential for fluorescent sensors,colorimetric sensors,and electrochemical sensors for dopamine detection.This review systematically examined the challenges and prospects for the utilization of CDs-based fluorescent sensors,electrochemical biosensors,and colorimetric sensors for monitoring dopamine levels in recent years.These findings unveil promising avenues for further advancements in the field of dopamine detection.
