Development of Microparticle Materials That Enable Innovative Adsorption of Biological Substances
Summary
Researchers developed porous pectin particles using a template-assisted spray drying method, achieving high protein adsorption capacity for potential use in food and pharmaceutical applications. Bio-based adsorption materials like these could have applications in capturing microplastics or associated contaminants from water.

Emerging Porous Materials for Adsorptive Removal of Microplastics and Nanoplastics from Aquatic Environments: A Review
This review summarizes recent advances in using porous materials, including sponges, aerogels, hydrogels, metal-organic frameworks, and carbon-based adsorbents, to remove microplastics and nanoplastics from water. Researchers found that adsorption using these materials is a promising, cost-effective approach that outperforms conventional water treatment methods for plastic particle removal. The study identifies key challenges and future research directions for developing practical adsorbents for real-world plastic pollution mitigation.
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.
Highly Efficient, Recyclable Microplastic Adsorption Enabled by Chitin Hydrogen Bond Network Rearrangement
Scientists developed a foam made from chitin, a natural material found in seafood shells, that can absorb over 400 milligrams of nano-sized microplastics per gram of material, even in saltwater. This recyclable, sustainable approach could help clean microplastics from ocean water, and the recovered plastic can be converted into useful products.
Nature-derived hydrogel for microplastic removal
Scientists developed a nature-based hydrogel made from chitin and lignin that can remove nanoplastics from wastewater with very high efficiency, absorbing up to 1,791 milligrams of plastic per gram of material. This sustainable, reusable filter could help reduce the amount of tiny plastic particles that reach drinking water and ultimately the human body.
Fabrication of O‑enriched macroporous polymer for the efficient adsorption organic acid from aqueous solution
Researchers created a porous polymer material rich in oxygen-containing groups that efficiently adsorbs organic acids from water, with adsorption capacities exceeding 400 mg/g for some compounds. The material can be regenerated for repeated use, making it a candidate for water purification applications.
