An enzyme-responsive fluorescent nanoemulsion based on lipophilic dye liquid was developed for alkaline phosphatase detection, showing higher sensitivity and shorter response time compared to conventional NE.
An enzyme-responsive fluorescent nanoemulsion (NE) based on lipophilic dye liquid (LDL) was developed for alkaline phosphatase (ALP). The response mechanism of the NE involved enzymatic reactions and simultaneous extraction of anions. The LDL-based NE exhibited 3.8 times higher sensitivity than plasticizer-based conventional NE. Detection limit and response range were 2.7 (U L-1) and 5-50 (U L-1), respectively. The response time was reduced to less than half that of the LDL-based membrane.
