Ecological characteristics of ?-cyclodextrin-bearing spherical PVA hydrogels as supports for microbial immobilization

Published on 2026-05-27 by Hirohito Yamasaki, Yui Iwamoto, Taiji Ito, Kimitoshi Fukunaga @NATURE

Abstract: Polymer Journal, Published online: 27 May 2026; doi:10.1038/s41428-026-01203-3We prepared a mixed-type PVA spherical hydrogel (PVA-mix-βCyD/HDI) was prepared, in which βCyD/HDI was accumulated and distributed at contents of 18–55 μmol g−1. The internetwork distance on the hydrogel surface increased from ~20 to 30 μm as the amount of β-CyD increased, as confirmed by SEM cross-sectional images. This trend is opposite to that observed for the homogeneously dispersed PVA-co-βCyD hydrog[...]


Our summary: The study investigates the ecological characteristics of β-cyclodextrin-bearing PVA hydrogels for microbial immobilization. A mixed-type PVA hydrogel was prepared, showing increased internetwork distance with higher β-CyD content. PhOH-degrading bacteria were effectively immobilized, enhancing degradation rates as β-CyD concentration increased.

Particles comprising a superabsorbent polymer and a quaternary ammonium compound

Patent published on the 2026-05-20 in EP under Ref EP4744685 by HARTMANN PAUL AG [DE] (Kettel Markus [de])

Abstract: The present invention relates to particles comprising a superabsorbent polymer (SAP) and a quaternary ammonium compound (Quat). The superabsorbent polymer is a crosslinked polyacrylate. The quaternary ammonium compound is antimicrobial and/or anti-inflammatory. Moreover, the quaternary ammonium compound is non-covalently linked to the superabsorbent polymer. The particles can thus be advantageously highly absorbent, antimicrobial, anti-inflammatory, easy to produce and inexpensive. Furthermore, [...]


Our summary: The invention describes particles made from a superabsorbent polymer and a quaternary ammonium compound. These particles are highly absorbent, antimicrobial, and anti-inflammatory. A process for producing these particles and a wound dressing incorporating them is also detailed.
