A novel thermoresponsive hydrogel based on chitosan

European Journal of Pharmaceutics and Biopharmaceutics, 2008
Injectable thermosetting chitosan hydrogels are attractive systems for drug delivery and tissue engineering that combine biodegradability, biocompatibility and the ability to form in situ gel-like implants. Thermally-induced gelation relies advantageously on biopolymer secondary interactions, avoiding potentially toxic polymerization reactions that may

Thermoresponsive Cellulosic Hydrogels with Cell-Releasing Behavior

ACS Applied Materials & Interfaces, 2013
Here we report the preparation and characterization of thermoresponsive cellulosic hydrogels with cell-releasing behavior. Hydroxypropyl cellulose (HPC) was modified with methacrylic anhydride (MA). The resultant macromonomer, HPC-MA, retains the characteristic thermoresponsive phase behavior of HPC, with an onset temperature of 36 °C and a lower ...

Thermoresponsive Nanocellulose Hydrogels with Tunable Mechanical Properties

ACS Macro Letters, 2014
Cellulose microfibrils physically bound together by soft hemicellulose chains form the scaffolding that makes plant cell walls strong. Inspired by this architecture, we designed biomimetic thermoreversible hydrogel networks based on reinforcing cellulose nanocrystals (CNC) and thermoresponsive methylcellulose (MC).

Thermoresponsive Microtubule Hydrogel with High Hierarchical Structure

Biomacromolecules, 2011
A thermoresponsive 3D microtubule hydrogel (MT gel) was prepared by simultaneous polymerization and chemical cross-linking of tubulins. The main chain of this gel is composed of cross-linked MTs, which consists of a cylindrical assembly of tubulin covalently connected by polyethylene glycol.

Thermoresponsive Hydrogel Scaffolds with Tailored Hydrophilic Pores

Chemistry – An Asian Journal, 2010
AbstractThermoresponsive hydrogels with efficient water‐release channels were prepared by incorporating star‐shaped macromolecular pore precursors, with degradable disulfide crosslinked cores and hydrophilic poly(ethylene oxide) (PEO) arms, into the gel network.

Rheological properties of thermoresponsive nanocomposite hydrogels

Journal of Applied Polymer Science, 2015
ABSTRACTHighly elastic and robust nanocomposite hydrogels based on N‐isopropylacrylamide (NIPAM) and cationic (3‐acrylamidopropyl) trimethylammonium chloride (AMPTMA) were synthesized by photopolymerization. Nanoscopic clay, laponite XLS, was added in the gels during the synthesis.

Thermoresponsive hydrogels with ultrasound-controlled properties

Russian Journal of General Chemistry, 2014
Possibility of creation of materials with transport properties operated by ultrasound on the basis of thermosensitive hydrogels modified by a solid phase of inorganic compounds is shown. The kinetic model of drug release from the hydrogel matrix, which allows to optimize the parameters of ultrasound exposure is proposed. Various options of devices with

Thermoresponsive Hydrogel with Thermal Memory

Advanced Materials
AbstractThermal plasticity—the capacity to dynamically reconfigure material properties in response to thermal history—is a hallmark of biological systems that remains elusive in synthetic hydrogels. Inspired by coral symbiont acclimatization, thermally plastic hydrogels (TP‐gels) based on polyvinyl butyral are reported, which emulate biological thermal

Distribution of Phenols in Thermoresponsive Hydrogels

Macromolecules, 2007
The effect of three hydrotropic molecules, phenol, resorcinol and phloroglucinol, on the thermodynamic equilibrium and the dynamics of poly(N-isopropylacrylamide) (PNIPA) hydrogels is reported. With increasing hydroxyl number of this molecular sequence both the depression of the temperature and the width of the volume phase transition (VPT) increase ...
