Abstract

Nanoparticles are promising plataforms for applications in biological systems due to their size and functionalization possibilities. However, loss of colloidal stability and formation of protein corona has hindered clinical translation of nanoparticles. This change in colloidal stability and the formation of protein corona influence the final characteristics of the nanoparticles and their physical-chemical properties. creating a new biological identity for the nanomaterial. The goal here is to study the colloidal stability and the protein corona formation over silica nanoparticles of approximately 100 nm with different surface modifications. Particularly, evaluation of silica nanoparticles with a zwitterionic silane will be studied, to elucidate aspects that grant colloidal stability to these nanoparticles when in biological fluids.
