a Fluorescence spectra of the hybrid microparticles after treatment with a mixture of 10 mM PPi and different ALP concentrations (0–400 mU/mL). b A linear curve of fluorescent intensity at 535 nm versus ALP concentration. c Reflection spectra of the particles with an initial reflection peak value at 441 nm (without ALP) immersed in a mixture of 10 mM PPi and different concentrations of ALP (0, 100, 200, 300, and 350 mU/mL). d The measured reflection peak shift value as a function of ALP concentration.
