Abstract
The present technology is directed to the nanoparticles for use as molecular environmental sensors. The nanoparticles comprise a photoluminescence core and a plurality of ligands bound to the core and forming a quencher permeable ligand shell. The ligands comprise a reactive or charged moiety capable of being modulated between a first stand and a second state, and the proportion of ligands in each state determine the permeability of the ligand shell to a photoluminescence quencher.
