One-step facile synthesis of N-acetylglucosamine-functionalized gold nanoparticles for direct visual and light-scattering detection of lectin from wheat germ

Here, we report the one-step synthesis of N-acetylglucosamine-functionalized gold nanoparticle (NAG–AuNP), which then served as a facile, economic, highly sensitive and selective sensor for the detection of lectin from wheat germ, based on colorimetric and resonance light scattering signals.
