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 ...

Surface‐Anchored Microgel‐Based Films as Anti‐Icing Coatings

Advanced Materials Interfaces, EarlyView.
The microgel‐based anti‐icing coatings presented in this work reduce ice adhesion by up to 90% on various substrates. This effect can be attributed to the incorporated functional cationic moieties binding a lubricating layer of quasi‐liquid interfacial water.

NIR Laser-Responsive PNIPAM and Gold Nanorod Composites for the Engineering of Thermally Reactive Drug Delivery Nanomedicine

Pharmaceutics, 2020
When ingesting a drug on its own or injecting it directly into tissue, its concentration increases immediately within the body, which often exacerbates the side effects and increases its toxicity.
