Surface-enhanced photochromic phenomena of phenylalanine adsorbed on tungsten oxidenanoparticles: a novel approach for “label-free” colorimetric sensing

Abstract

The enhanced photochromic behaviors of the L-phenylalanine (Phe)–tungsten(VI) oxide (WO3) colloid binary aqueous solution have been investigated by means of UV-vis absorption spectrometry. The phenomena provided a potential use of the WO3 nanoparticles as a colorimetric probe for sensitive “label-free” detection of Phe.
