Recent progress and prospects of alkaline phosphatase biosensor based on fluorescence strategy

Alkaline phosphatase (ALP) is a membrane-bound enzyme widely present in biological tissues and is extensively used as a biomarker in clinical diagnosis because abnormal ALP levels in organisms are often closely related to many diseases. In order to meet the urgent needs of human health and the development of precision medicine, the classic method of detecting ALP seems to be unable to meet a "tailor-made" treatment plan for patients. In order to get the best therapeutic effect and the lowest side effects, the researchers have made considerable efforts and established numerous strategies for detecting ALP. In this review, we focus on the current development and basic principles of fluorescence strategy to detect ALP, and compare the advantages and disadvantages of detecting ALP based on different fluorescent detection modes. In addition, to more intuitively understand the performance of different materials for detecting ALP, a table is presented. Finally, the future trends and prospective in this field will be discussed, it could be speculated that invent and design the detection mechanism based on the relationship between the new material and ALP is the key to effective detection of ALP, and process data with a computer analog digital platform will be a welcome and obsessive technology. It is hoped that some insights and inspiration for future research work will be provided.
