Toxicity Assessment of Upconverting Nanoparticles – Current Perspectives

The growing use of upconverting nanoparticles (UCNPs) in biomedical applications and therapy approaches necessitates a rigorous assessment of their potential toxicity. Current understandings highlight the difficulty in predicting UCNP fate *in vivo* due to factors such as size variability, surface modification, and the existence of stabilizing agents. Initial research often addressed on *in vitro* cell damage using standardized assays, but these may not reliably represent *in vivo* responses. New research are increasingly integrating additional endpoints, like free radical stress, immune responses, and DNA risk. Moreover, long-term duration effects and localization remain significant challenges for ongoing investigation.
