Abstract
Fluorescent nanosensors for extracellular ion concentration measurements are disclosed herein. More specifically, a fluorescent nanosensor for extracellular ion measurements comprising a photoluminescent nanostructure disposed on a substrate surface is disclosed. The photoluminescent nanostructure comprises a fluorescent metallic core-silica shell containing nanoparticle, wherein the fluorescent silica shell comprises a fluorophore dispersed therein. The nanosensor emits a fluorescence emission in function of the extracellular ion concentration.
