Cytocompatibility of Hafnium Oxide (HfO_2) Nanoparticles for Diagnostic Imaging and Sensing

摘要

Conclusions: HfO_2 NPs exhibited no cytotoxicity at concentrations up to 0.833 mg/mL in both HeLa and THP-1 cells. Therefore, the results of this study suggest that HfO_2 NPs are suitable as an in vivo imaging probe and in vitro diagnostic biosensor.
