Ultrasensitive surface-enhanced Raman scattering detection of alkaline phosphatase

Abstract

In this study, an ultrasensitive surface-enhanced Raman scattering (SERS) detection of alkaline phosphatase (ALP) has been developed, in which nile blue A (NBA) was chosen to replace nitro blue tetrazolium chloride (NBT) in a reactive system of 5-bromo-4-chloro-3-indolyl phosphate (BCIP), NBT, and ALP.
