Microplastic Transport in Buckwheat Root-Inspired Microfluidic Structures: Microfluidic and Numerical Analysis
Summary
Researchers modeled and experimentally replicated microplastic transport through microfluidic channels inspired by buckwheat root epidermal tissue, finding that particles follow streamlines under laminar flow but accumulate at pore-like constrictions—suggesting outer root layers act as a partial size-selective filtration barrier for soil microplastics.
) roots revealed a well-defined epidermal and cortical tissue organization, which served as a basis for designing simplified epidermis-inspired microchannel geometries. Numerical simulations and microfluidic experiments showed that microplastics predominantly follow streamline-oriented pathways under laminar flow conditions. However, particle accumulation can induce localized clogging within pore-like structures, modifying flow pathways and redirecting particle transport. These results indicate that root epidermal tissues may function as a partial filtration barrier that restricts the transport of larger microplastics while allowing smaller particles to migrate through outer root layers.
