Superiorities of nanoscale materials in drug delivery

Abstract In the last few decades, nanomaterials have been intensively researched for numerous biomedical applications, including targeted drug delivery, due to their unique properties such as dimensions, biocompatibility, surface chemistry, stability in physiological conditions, and modifiable toxicity. The toxicity of nanomaterials can prove to be a challenging subject, however changing different physicochemical properties of nanomaterials can alter their toxic behavior. Further research needs to be done on in vivo toxicity based on the physiological effect of acute and chronic adverse effects caused by nanoparticles. In order to properly and safely design future nanotechnologies, there is a need for a fundamental understanding of the interactions between nanomaterials and biological tissues.
