Thermoresponsive and Redox Behaviors of Poly(N-isopropylacrylamide)-Based Block Copolymers Having TEMPO Groups as Their Side Chains

open access: yesInternational Journal of Polymer Science, 2013
Thermoresponsive and redox-active block copolymers having 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) moieties have been synthesized by using the reversible addition-fragmentation chain transfer (RAFT) polymerization technique.

Bioartificial polymeric materials based on collagen and poly(N-isopropylacrylamide)

open access: yesMaterials Research, 2007
Films of collagen (CLG) and poly(N-isopropylacrylamide), PNIPAAm, were prepared by casting from water solutions. These bioartificial polymeric materials were studied to examine the influence of PNIPAAm content and glutaraldehyde vapor cross-linking on ...

Reverse Thermo‐Responsive Nanoshells: The Interplay Between the Composition of Their Building Blocks and Their Temperature‐Responsive Morphing

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
The graphical abstract shows hollow polymeric nanoshells from crosslinked PEO–PPO–PEO with methacrylate end‐groups. These shells expand at low temperatures (6 °C, ∼310 nm) and shrink at 37 °C (∼35 nm)—a 700‐fold volume change. This reverse thermo‐responsiveness, driven by polymer coiling–uncoiling, enables potential biomedical applications like ...

Hydrogel‐based drug delivery systems for intracerebral hemorrhage with therapeutic advances and emerging roles of the bone–brain axis

open access: yesInterdisciplinary Medicine, Volume 4, Issue 4, July 2026.
Hydrogel‐based drug delivery systems offer a promising approach for treating intracerebral hemorrhage (ICH) by overcoming blood‐brain barrier limitations, enabling precise, sustained release of neuroprotective and anti‐inflammatory agents. These systems enhance treatment efficacy, but challenges remain in biosafety, drug penetration, and scalability ...

Thermosensitive Nanocables Prepared by Surface-Initiated Atom Transfer Radical Polymerization

open access: yesNanoscale Research Letters, 2008
Thermosensitive nanocables consisting of Au nanowire cores and poly(N-isopropylacrylamide) sheaths (denoted as Au/PNIPAAm) were synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP).

Resistência mecânica de hidrogéis termo-sensíveis constituídos de Alginato-Ca2+ / PNIPAAm, tipo Semi-IPN Mechanicals resistance of thermosensitive hydrogels consisting of alginate-Ca2+ / PNIPAAm, type Semi-IPN

open access: yesQuímica Nova, 2007
Thermosensitive hydrogels were synthesized using alginate-Ca2+ in association with a thermosensitive polymer, such as PNIPAAm. The mechanical properties of the hydrogels were determined measuring the maximum tension of deformation.
