The optimized geometrical structure, vibrational and electronic transitions, chemical shifts and nonlinear optical properties of 2-(4-hydroxyphenylazo)benzoic acid (HABA) compound were presented in this study. The ground state geometrical structure and vibrational wavenumbers were carried out by using density functional (DFT/B3LYP)

This study reports a homogeneous and competitive fluorescence quenching immunoassay based on gold nanoparticle/polyelectrolyte (Au(NP)/PE) coated latex particles prepared by the layer-by-layer (LbL) technique. First, the resonant energy transfer from a layer of fluorescent PEs to Au(NP) in LbL assembled
