Determination of metallic nanoparticles in biological samples by single particle ICP-MS: a systematic review from sample collection to analysis
Summary
This systematic review found that single particle ICP-MS analysis of engineered nanomaterials in biological samples has focused on only a few nanoparticle compositions, primarily silver and gold, while leaving significant gaps for other materials and important tissue types. The technique enables detection and characterization of individual nanoparticles within complex biological matrices. Similar analytical challenges exist in microplastic research, where detecting and characterizing nano-sized plastic particles in biological tissues remains technically demanding.
A systematic review of the use of single particle ICP-MS to analyse engineered nanomaterials in biological samples has highlighted that efforts have focused on a select few compositions and there is a lack of information for some important tissues.
