Fluorescence has been used in many different fields such as imaging and sensing. Fluorescence self-quenching is a unique property that occurs at high concentrations, resulting in reduced emission intensities. This study aims to demonstrate the emission enhancement of fluorescein encapsulated in liposomes. The emission was observed to be enhanced when gold nanoparticles were added to liposome-encapsulated...
Copper (II) determination with a three-dimensional monolayer modified electrode prepared by assembling L-cysteine on gold nanoparticles (L-cys/GNP/GCE) was studied in this paper. With the presence of gold nanoparticles, three-dimensional L-cysteine monolayer-modified electrode showed better voltammetric response for copper (II) than traditional two-dimensional L-cysteine assembled on planar electrode...
