Ex Vivo Evaluation of Poly(Solketal Acrylate) Nanoparticles for Intravitreal Drug Delivery to the Posterior Eye Segment

Macromolecular Rapid Communications, EarlyView.
Nile Red‐loaded poly(solketal acrylate) nanoparticles enable fluorescence tracking and exhibit nontoxic profiles in retinal cells. Enhanced cellular uptake and deep retinal penetration after intravitreal injection highlight their excellent potential for targeted ocular drug delivery to the posterior segment of the eye.

Multi‐Responsive PAA/PNIPAM Semi‐IPN Hydrogel Properties Controlled by PAA Topology

Macromolecular Rapid Communications, EarlyView.
Polymer topology governs hydrogel behavior in semi‐interpenetrating networks. Cyclic poly(acrylic acid) enables controlled pH‐responsive swelling, improved stability, and enhanced deformability compared to linear analogues, while linear systems show higher strength during thermal de‐swelling.

Synthesis of Poly(Itaconate)s With High Monomer Conversion Applying Emulsion Polymerization

Journal of Polymer Science, Volume 63, Issue 6, Page 1284-1296, 15 March 2025.
Itaconic acid and its derivatives are a promising and bio‐based substitute for oil‐based polymers such as acrylates. In this study, the optimization of polymerization of itaconic acid esters is described by applying emulsion polymerization leading to high reaction conversions and low residual monomer contents. ABSTRACT Itaconic acid and its derivatives
