Supplementary MaterialsESI. biocompatible, surface area functionalization could be released, and their diameters could be easily tuned.31,33,34 Control over the size of the precursor particles is especially important as nanomaterials smaller than 70 nm have been shown to readily penetrate the skin causing detrimental side effects.35,36,37 Therefore, we synthesized cationic amine-functionalized SiO2 NPs with an average… Continue reading Supplementary MaterialsESI. biocompatible, surface area functionalization could be released, and their
