Tuning catalytic activity and sensitivity in urease‐based thin film biosensors using conjugated polymers and eugenol/biseugenol

Polymer International, EarlyView.
Hybrid thin films of conjugated polymers and urease modified with eugenol derivatives show that polymer–biomolecule interactions enhance catalytic activity while distinctly modulating electrolyte–insulator–semiconductor sensor sensitivity. Abstract Thin films have emerged as promising platforms for biosensor development due to their versatility and ...

Main‐chain polyfullerenes: Taking fullerene to the next dimension

Polymer International, EarlyView.
This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.

Hydrogen Atom Transfer Induces Photodegradation in Carbonyl‐Based Multi‐Resonance TADF Emitters

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Boosting triplet harvesting in N/C═O MR‐TADF emitters unexpectedly induces rapid photodegradation under oxygen‐free conditions. Spectroscopic studies reveal that triplet excited states trigger hydrogen‐atom transfer from solvent to the carbonyl unit, driven by triplet energetics and hydrogen electrophilicity.

Dynamics of end-linked star polymer structures

, 2005
In this work we focus on the dynamics of macromolecular networks formed by end-linking identical polymer stars. The resulting macromolecular network can then be viewed as consisting of spacers which connect branching points (the cores of the stars).

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

Journal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...

Origin of broad polydispersion in functionalized dendrimers and its effects on cancer cell binding affinity

, 2010
Nanoparticles with multiple ligands have been proposed for use in nanomedicine. The multiple targeting ligands on each nanoparticle can bind to several locations on a cell surface facilitating both drug targeting and uptake.
