Thermisch kontrollierter chiraler supramolekularer Polymorphismus in Wasser

open access: yesAngewandte Chemie, EarlyView.
Unter Verwendung eines amphiphilen Oligophenylenethinylen Derivats haben wir LCST‐gekoppelte Chiralität als Strategie zur Regulierung von thermoresponsivem supramolekularem Polymorphismus in Wasser etabliert. Bei Raumtemperatur bildet AggI diskrete Ansammlungen, die in der Nähe des LCST in elongierte helikale Fasern (AggII) übergehen und schlussendlich

Thermally Controlled Chiral Supramolecular Polymorphism in Water

open access: yesAngewandte Chemie International Edition, EarlyView.
Using an amphiphilic oligo(phenyleneethynylene) derivative, we establish LCST‐coupled chirality as a strategy to regulate thermoresponsive supramolecular polymorphism in water. At room temperature, AggI forms discrete assemblies that transform into elongated helical fibers (AggII) near the LCST and subsequently to sheet‐like structures (AggIII) at ...

On the Molecular Origin of the Cooperative Coil-to-globule Transition of Poly(N-isopropylacrylamide) in Water

open access: yes, 2018
By means of atomistic molecular dynamics simulations we investigate the behaviour of poly(N-isopropylacrylamide), PNIPAM, in water at temperatures below and above the lower critical solution temperature (LCST), including the undercooled regime.

A novel biomimetic liposome drug delivery system mediated by macrophage targeting for precision treatment of encephalitis

open access: yesBMEMat, EarlyView.
An advanced macrophage‐mediated biomimetic liposome (AC‐LP@RAW) that can penetrate the BBB and precisely target inflammatory sites in the deep brain was established in this study based on the unique immune homing property of macrophages, and showed a significantly improved delivery of curcumin to the brain.

Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers

open access: yesChemistry – A European Journal, EarlyView.
Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.

Inter‐Verified Binary Classification Models: Unveiling Key Polymer Features Against Staphylococcus aureus

open access: yesCarbon Innovation, EarlyView.
ABSTRACT Antimicrobial peptides (AMPs) are promising alternatives to antibiotics but require precise and costly sequence control for efficacy. Synthetic polymers composed of acrylate and acrylamide offer a simpler and more time‐efficient antibacterial strategy compared to AMPs.

Redox Biocatalysis in Lidocaine‐Based Hydrophobic Deep Eutectic Solvents: Non‐Conventional Media Outperform Aqueous Conditions

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Two hydrophobic DESs, lidocaine/oleic acid and lidocaine/decanoic acid, were utilized as reaction media that were enzyme‐compatible and highly substrate‐solubilizer for carbonyl reduction catalyzed by horse liver alcohol dehydrogenase, focusing on the effect of water contents and on maximizing substrate loadings, which showcases for the first time the ...
