A StraightforwardApproach for the Removal of Microplasticsfrom Water: Utilization of SLIPS
Summary
Researchers demonstrated for the first time that slippery liquid-infused porous surfaces (SLIPS) can rapidly and efficiently remove polystyrene microplastics from water, with the slippery surface capturing particles through size-independent adhesion without requiring filters or chemical treatment.
Microplastics (MPs), as a problematic pollutant in the 21st century, have been found in seawater, surface water, soil, plants, animals, and the human body. This pollutant has detrimental effects on the environment and human health. Therefore, the removal of MPs from our ecosystem is an emerging demand. Herein, a straightforward strategy for the removal of MPs from water is presented. The utilization of slippery liquid-infused porous surface (SLIPS) for MPs removal from aqueous media is introduced in this work for the first time as a fast, simple, and highly efficient method. Polystyrene MPs were removed with high yield and rapidly from water by using a laser-ablated plexiglass (poly(methyl methacrylate)) infused with silicon oil, and the mechanism of this process is suggested. This work introduces a research area (MPs removal with SLIPS), which is very crucial for the environment and human health.

Molecular Mechanisms Governing the Adsorption, Deposition, and Removal of Environmentally Aged Microplastics by Engineered Surfaces
Scientists figured out how tiny plastic particles that have been weathered in the environment stick to different surfaces, then used this knowledge to create a new material that can remove over 92% of these microplastics from water. This breakthrough could lead to better filters and cleanup systems to remove microplastics from drinking water and the environment. Since microplastics are found everywhere from our food to our bloodstream, having effective ways to remove them could help protect human health.
