Visual and light scattering spectrometric method for the detection of melamine using uracil 5′-triphosphate sodium modified gold nanoparticles

The highly selective method was presented for colorimetric determination of melamine using uracil 5′-triphosphate sodium modified gold nanoparticles (UTP-Au NPs) based on the specific hydrogen-bonding interaction between uracil base (U) and melamine.241
