Reversible Tuning of Multiple Molecular Kinking for Stem Cell Regulation In Vivo

open access: yesAdvanced Functional Materials, EarlyView.
In this work, we introduce the novel concept of background component‐free “multiple kinks” material platform composed solely of liganded multiple kink‐bearing molecules as a strategy for dynamic biomaterial design. Tri‐kink molecules enable effective near‐infrared light‐triggered ligand masking and visible light‐triggered ligand exposure, thereby ...

Evaluation Of Antioxidant Activity Of 1, 2, 4-Triazole Derivatives With Morpholine Moiety

open access: yesHacettepe University Journal of the Faculty of Pharmacy, 2022
The aim of the work was to study the antioxidant activity of 4-R-3- (morpholinomethyl)-4H-1,2,4-triazole-5-thioles and their alkyl derivatives in vitro using the method of non-enzymatic initiation of lipid peroxidation. Among the 45 compounds studied, 8 showed varying degrees of AOA.

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

open access: yesAdvanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

open access: yesAngewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...
