A fluorescein-gold nanoparticles probe based on inner filter effect and aggregation for sensing of biothiols
{{output}}
Cysteine (Cys), homocysteine (HCys) and glutathione (GSH) are sulfhydryl-containing amino acids known as biothiols being able to bind to gold nanoparticles (AuNPs) via sulfhydryl group, resulting in the aggregation of AuNPs. Owning to their inner filter effect... ...
