Nanosafety for Green Nanotechnology
October 12, 2019

China is one of countries that are industrially produce the most amount of nanomaterials/nanoparticles (NMs/NPs). In order to fill in the knowledge gaps in the green production technique of nanomaterials and nano-products, we have been studying the occupationally and environmental health effects of nanomaterials in working places. To determine the composition, spatial distribution, and states of existence of NMs/NPs in vivo, upon entry into the body, as well as to monitor the dynamic changes of these information over time remain a challenge for the current analytical methodology due to their limited efficiently in characterizing interactions between these complex(nano)-complex(bio) systems. NMs/NPs are more complicated compared with the classic chemical molecules, ions or elements, while biological systems pose even greater difficulties being a complicated network of chemical/biological composition, multihierarchical structures, the highly dynamic nature, nonequilibrium states and nonlinear chemical processes, etc. Thus, although some existing methods/protocols have promoted the understanding of how NMs/NPs interact with biological systems, almost none of these are fully adequate for quantitative analyses. Recently, it was recognized that quantitative analysis method are necessary for the accurate characterization of the complicated behaviors of NMs/NPs in vivo. In the talk, we discuss the analytical methodology and techniques developed for the quantification of the ADME processes of NMs/NPs in vivo, focusing on those used for NMs/NPs quantification in different bio-matrices, such as blood, tissues, organs and biomedical processes. By summarizing the advantages and limitations of these methods, we hope that this may assist the future development of green nanotechnologies.
