Colorimetric detection of alkaline phosphatase activity based on pyridoxal phosphate–induced chromatic switch of polydiacetylene nano-liposomes

Recent progress in the design of conjugated polydiacetylenes with reversible thermochromic performance: a review

“…Therefore, the obvious property changes with external stimuli detected by the naked eye make PDA an excellent material for the design of sensors. 11–18…”

“…Therefore, the obvious property changes with external stimuli detected by the naked eye make PDA an excellent material for the design of sensors. [11][12][13][14][15][16][17][18] Although the blue to red color transition can take place with the application of external stimuli, major PDA-based systems exhibit colorimetric irreversibility when the external stimulus is removed. Meanwhile, the color transition triggered by temperature is of great significance because temperature is a basic environmental stimulus and plays an important role in many natural and engineered processes necessary for living organisms.…”

Fe–N hollow mesoporous carbon spheres with high oxidase-like activity for sensitive detection of alkaline phosphatase

“…However, the instabil-ity of p-NPP to light and heat limit its practical application prospect. 13,14 Therefore, it is meaningful to explore new colorimetric strategies for highly sensitive and reliable detection of ALP activity.…”
