Nanomaterials in complex matrix

Analyzing nanoparticles within complex mixtures or matrices poses considerable challenges compared to examining pure nanomaterial samples. The presence of heterogeneity and the potential for interference from surrounding substances make characterizing nanoparticles vastly more complex and, at times, seemingly insurmountable.

Fortunately, our team has accumulated substantial expertise in the characterization of nanomaterials under such intricate conditions. For instance, we've delved into the study of CuO and Cu(OH)2 nanoparticles in biological samples embedded within resin, though this research remains unpublished. Additionally, our investigation into TiO2 nanoparticles within soil was published in Environmental Science: Nano in 2020, and some of our findings concerning Ag and ZnO nanoparticles in silkworms were shared in Chemosphere in 2020. Furthermore, I've been awarded a grant from Nottingham University due to my proficiency in nanomaterial characterization within complex media, enabling me to develop a protocol for detecting nanoplastics in the environment.

In summary, characterizing nanoparticles within complex media or matrices presents formidable obstacles, but our wealth of experience and successful research endeavors in this area demonstrate our ability to surmount these challenges effectively. This expertise is instrumental in advancing our comprehension of nanoparticle behavior and their impact within real-world contexts, including environmental and biological settings.
