Nanoplastics in living cells, OPUS no. 2021/41/B/ST4/00464, 2/2022
Project leader
Prof. Robert Hołyst
Description
Plastic nanoparticles (PNP) (nanoplastics) pollute water and air and accumulate in cells. Accumulation leads to crowding of the cytoplasm, which influences transport of biomolecules. Impaired transport negatively affects all cellular processes. We do not know how significant this impairment is and how it depends on the concentrations of PNP. The project aims at solving this problem. Proposed physical methods (FCS, RICS, microfluidics, precise analysis of fluorescence) that meet this challenge supplement those currently used by biologists. We will supplement study of transport with uptake and removal kinetics of plastic nanoparticles, their partition coefficient between cells and medium (and/or maximum capacity load), and standard viability tests. If uptake of plastic nanoparticles is irreversible then partition coefficient should be replaced by the maximum load (capacity) of cells for accommodation of NP. Our results obtained for a wide range of PNP concentrations (1 pM up to 1 µM), sizes (10 nm – 200 nm), and time scales (~ ms to hours) will provide vitally needed information to World Health Organization (WHO). (information based on the press release (22 August 2019) and WHO report 2019 https://www.who.int/water_sanitation_health/publications/microplastics-indrinking-water/en/ ).
This project is timely, as also explained by the Editorial Material, "Nanoplastic should be better understood" published in Nature Nanotechnology (April 2019). Although the project is in the
physical chemistry domain, some standard biological tests must be added to obtain a complete picture of changes induced by crowding cells with nanoplastics. We will correlate standard biological tests with impaired transport in cells. Such a correlation will introduce a new dimension in the scientific approach to cell viability since impaired transport affects all biochemical processes in cells.
