Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

Macromolecular Rapid Communications, Volume 47, Issue 8, 17 April 2026.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.

Controlled Release of Metformin Hydrogen Chloride from Stimuli-responsive Hydrogel based on Poly(N- Isopropylacrylamide)/Chitosan/Polyvinyl Alcohol Composite

International Journal of Technology, 2020
Hydrogels are ideal biomaterials owing to their unique network structure that facilitates considerable hydrophilicity and biocompatibility. At the same time, hydrogels also possess soft physical properties when combined with living tissue.

Development of Tunable Materials From Well‐Defined Alendronic Acid Functionalized Polyacrylamide: An Opportunity for Actinide Decontamination

Journal of Polymer Science, Volume 64, Issue 6, Page 1431-1443, 15 March 2026.
Alendronate‐based copolymers for Nd and Ce recovery. ABSTRACT Bisphosphonic acid groups are emerging as promising functionalities for actinide decontamination, due to their high density of chelating sites. However, the chemistry of bisphosphonate (in particular alendronate) materials remains complex and underexplored.
