Sažetak
MOTIVATION Upconverting nanoparticles (UPNPs) have lately emerged as candidates for bio-imaging and bio-sensing applications, 1 making the evaluation of their biocompatibility and safety an important task. Presently, biomedical evaluation of metallic nanoparticles (NPs) is based on in vitro assays.2 Due to their unique physicochemical properties, such as large surface area and reactivity, NPs are known to interfere with assay components and detection systems.3 RESULTS The aim of this study was to investigate the interferences caused by differently functionalized UPNPs with conventional cytotoxicity tests. We performed a number of common in vitro assays that determine metabolic activity (MTT and MTS reduction) and oxidative stress (DCFH-DA oxidation, total glutathione level) to assess cytotoxicity. The results demonstrated applicability of different in vitro assays for safety evaluation of UPNPs. The extent and type of interference depended on the UPNPs concentration and the type of assay. CONCLUSIONS This study demonstrates the need for appropriate adaptations of experimental design when conducting cytotoxicity studies of UPNPs, and highlights different approaches to more accurately assess nanotoxicity.
