Publikováno v: Surface and Interface Analysis. 45:230-233
To understand the potential toxicity of nanoparticles (NPs), it is necessary to evaluate their penetration in biological tissues. For that, cell imaging can be considered as an indispensable diagnosis method. We have used the NanoSIMS50 to detect par
