1. Fluorinated metal nanoparticles (f-MNPs) stabilized aqueous droplets comprising f-MNPs, the f-MNPs comprising: a plurality of metal nanoparticles or semiconductor nanoparticles having size greater than 20 nm in cross-section, each of the nanoparticles being coated with fluorinated alkyl ligands that make the surface of the nanoparticles fluorophilic, wherein the f-MNPs function as surfactants for stabilizing aqueous droplets containing an aqueous core, wherein the f-MNPs stabilized aqueous droplets are suspended in a fluorinated solvent, wherein the diameter of the stabilized droplets ranges from 5 μm to 500 μm, and wherein the droplets contain at least one biomolecule and chemical reagent.
