An improved protocol for ICP-MS-based assessment of the cellular uptake of metal-based nanoparticles

Along with a growing interest in biomedical applications of metal-based nanoparticles, there is a compelling need in systematic information on their behavior in human body systems, preferably at the cellular level. However, in most of the in-vitro uptake experiments, the nanomaterial was applied in its native form that in reality can hardly reach the cell. In this work, we developed an improved procedure in which prior to addition to the cells...
