Enrichment of Hyaluronic Acid Binding Tumor Cells by Modulation of Selective Adhesion on Microgel Surfaces

open access: yesMacromolecular Rapid Communications, EarlyView.
We have developed a thermoresponsive microgel system for the selective enrichment of hyaluronic acid‐binding tumor cells. By modulating the adhesion on the microgel surface via temperature changes from 37°C to 30°C, we demonstrate a novel proof‐of‐principle for separating these tumor cell from white blood cells, which has potential applications in ...

Tuning LCST with thiol-responsiveness of thermoresponsive copolymers containing pendant disulfides

open access: yesChem. Commun., 2013
A new approach that centers on modulating the hydrophobic-hydrophilic balance by conversion of pendant disulfides to thiols and further to sulfides enables facile tuning of the thermoresponsive properties of thiol-responsive copolymers.

Catechol‐Containing Poly(2‐isopropyl‐2‐oxazoline): Synthesis and Thermoresponsive Behavior in Aqueous Salt Solutions

open access: yesMacromolecular Rapid Communications, EarlyView.
Polymers carrying catechol groups are interesting mussel‐inspired materials for wet adhesion applications or metal ion complexation for wastewater treatment. Here, catechol‐containing poly(2‐isopropyl‐2‐oxazoline)s were synthesized via microwave‐assisted cationic (co)polymerization and examined with regard to their thermoresponsive LCST behavior in ...

A Non‐Antigenic Randomized Polyethylene Glycol/Poly(2‐Phenyl‐2‐Oxazine)‐Based Drug Delivery Platform

open access: yesMacromolecular Rapid Communications, EarlyView.
Randomized PEG (rPEG), a conceptually new PEG alternative, is combined with poly(2‐phenyl‐2‐oxazine) (PPheOzi) to establish an rPEG‐b‐PPheOzi‐b‐rPEG micellar drug delivery platform. The PPheOzi block enables high drug loadings, while competitive ELISA reveals a drastic reduction in anti‐PEG antibody affinity of rPEG in comparison to PEG.

Conjugates of methylated cyclodextrin derivatives and hydroxyethyl starch (HES): Synthesis, cytotoxicity and inclusion of anaesthetic actives

open access: yesBeilstein Journal of Organic Chemistry, 2014
The mono-6-deoxy-6-azides of 2,6-di-O-methyl-β-cyclodextrin (DIMEB) and randomly methylated-β-cyclodextrin (RAMEB) were conjugated to propargylated hydroxyethyl starch (HES) by Cu+-catalysed [2 + 3] cycloaddition.

Exploring Use of an Orthogonal Crosslinker to Create Controlled Thermoresponsive Hydrogels from LCST Tunable Thermoresponsive Polymers

open access: yesMacromolecular Rapid Communications, EarlyView.
Thermoresponsive hydrogels with a tunable phase transition temperature are formed with control using an orthogonal reaction method. Living cationic polymerization enables control over the thermoresponsive polymer structures and the inclusion of an orthogonal crosslinker with both vinyl ether and methacrylate moieties enabled a facile post ...

LCST phase behavior of benzo-21-crown-7 with different alkyl chains

open access: yesBeilstein Journal of Organic Chemistry, 2019
The introduction of hydrophobic units into crown ethers can dramatically decrease the critical transition temperature of LCST and realize macroscopic phase separation at low to moderate temperature and concentration.

Copolymer Synthesis of N‐Vinylacetamide and 2‐Methylene‐1,3‐Dioxepane Provides a New Degradable Polymer

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1306-1318, 15 March 2025.
ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.
