Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

Integrated Multiband Smart Windows From UV to LWIR Based on Molecularly Engineered Thermochromic Hydrogels

Advanced Functional Materials, EarlyView.
A multiband smart window integrating a thermochromic poly (EEEA‐co‐NIPAM) hydrogel with functional layers, enabling dynamic VIS‐NIR solar modulation alongside UV shielding and low LWIR emissivity. The polymer network forms hydrogen‐bonding interactions, promoting chain collapse above a reduced lower critical solution temperature, and accelerating the ...

The Antiproliferative Effect of Celecoxib Loaded pNIPAM Nanoparticles

Journal of Biomaterials and Tissue Engineering, 2012
The aim of this study was to design a drug delivery system based on poly(N-isopropylacrylamide) (pNIPAM) nanoparticles (NPs). The model drug, Celecoxib, is a cyclooxygenase-2 inhibitor and has a great potential in chemoprevention and treatment of various cancer types, however, the clinical use is limited due to the side effects on the cardiovascular ...
