These cavitary hydrogel containers demonstrate thermal-responsive gate systems with unique sustained release at higher temperature and potential reaction containers for oxygen generation on demand. Previous workers have reported on the fabrication of temperature-responsive hydrogel valves [36-39]. Hereby, we developed a revolutionary high energy storage thermo-responsive smart window (HTEST smart window), which leverages high solar energy modulation together with high TES capability intrinsic in water-rich thermo-responsive liquid … Supramolecular protein hydrogels with tunable properties represent promising candidates for advanced designer extracellular matrices (ECMs). A switchable dual light- and temperature-responsive drug carrier using gold nanoparticles (Au NPs)-grafted poly (dimethylacrylamide-co-acrylamide)/poly acrylic acid [P (DMA-co-AAm)/PAAc] hydrogel was prepared by free radical polymerization procedure using N,N-methylenebisacrylamide as cross-linker and ammonium persulfate as initiator. Polymers with LCST can form negatively temperature sensitive hydrogels, the polymers shrink along with the temperature increases. Temperature Responsive Hydrogel for Nanoparticle Synthesis and Environmental Catalysis Number: 61/551,631 Year: 2011 Patent Status: Expired Authors: Bhattacharyya, D., L. Xiao. The morphologies of the resultant hydrogel-coated nanoshells were analyzed by scanning electron microscopy (SEM), while the temperature-responsive behavior of the nanoparticles was characterized by dynamic light scattering (DLS). This facile spatial surface-interior separation strategy for fabricating closed cavity systems has great potential for various applications. This site uses cookies. Temperature sensitive hydrogels can be divided into negatively thermo-sensitive and positively thermo-sensitive hydrogels according to their temperature-sensitive structure (Liu et al., 2006). We report nanothin temperature-responsive hydrogel films of poly(N-vinylcaprolactam) nanoparticles (νPVCL) with remarkably high loading capacity for topical drug delivery. of a temperature responsive hydrogel, poly(N-isopropylacrylamide) (PNIPAAm), were im-proved by adopting a low temperature polymerization process and adding a silicate com-pound, tetramethyl orthosilicate. Temperature-responsive hydrogel Download PDF Info Publication number JPWO2005010080A1. The gold nanoshells used for this study were ~160 nm in diameter, and the thickness of the P(NIPAM-co-AA) hydrogel was ~200 nm, as characterized by SEM and DLS. And it proved that cells formed filo podia-like structures in response to mechanical cues, suggesting that mechanical forces facilitated actin polymerization at the peripheral region. Poly (N-isopropylacrylamide) (PNIPAAm) has been extensively studied due to its unique thermo-responsive swelling behavior. For example, Yu et al. Temperature-responsive hydrogel fibers with bilayer structure were prepared by a microfluidic spinning device with a Y-shaped connector. In this study, a novel pH/temperature responsive micelle-laden hydrogel based on tremella polysaccharide (WSK), carboxymethyl cellulose (CMC) and nonionic surfactant-decyl polyglucoside (C 10 APG) was fabricated through radical polymerization by crosslinking N-isopropylacrylamide (NIPAM), for the purpose to achieve controlled release of hydrophobic drugs … The bilayer hydrogel fibers include two layer with different chemical composition. The temperature-responsive hydrogel can provide repetitive deformation, which is a good feature for micro soft robots or actuators, using hydrogel shrinking and swelling. Temperature-responsive hydrogel fibers with bilayer structure were prepared by a microfluidic spinning device with a Y-shaped connector. The bilayer hydrogel fibers include two layer with different chemical composition. prepared monolithic plugs of hydrogel by photo-initiated polymerization within the conduits of a microfluidic device and demonstrated over 120 open-close cycles [37]. These nanoparticles are stabilized in the hydrogel network and the dechlorination (using trichloroethylene, TCE, as a model compound) reactivity in water is enhanced and controllable in the temperature range of 30–34°C involving polymer domain transitions at lower critical solution temperature (LCST) from hydrophilic to collapsed hydrophobic state. Through the host–guest interaction in aqueous … Here, we developed an injectable system based on a temperature-responsive hydrogel and stromal cell-derived factor-1 (SDF-1)/vascular endothelial growth factor (VEGF) loaded into two types of nanoparticles to induce migration and rapid proliferation of mesenchymal stem cells (MSCs) and endothelial cells (ECs) via selective SDF-1/VEGF release. For example, a medical patch moving in the body and deploying at a targeted region can be developed by applying the self-rolling up method and magnetic manipulation [27–30]. Most supramolecular motifs are inherently temperature-sensitive, with elevated temperatures commonly disfavoring motif formation and/or accelerating its dissociation. Research output: Contribution to journal › Article › peer-review. In the context of biomedical uses, temperature is an interesting stimulus which has been the focus of numerous hydrogel designs, supramolecular or otherwise. Google Scholar. Construction of novel temperature-responsive hydrogel culture system based on the biomimetic method for stem cell sheet harvest. Temperature-responsive hydrogel-coated gold nanoshells were prepared using a rationally-designed surface-bound initiator. Stimuli-responsive hydrogels formed by various natural and synthetic polymers are capable of showing distinctive changes in their properties with external stimuli like temperature, pH, light, ionic changes, and redox potential. "Contrasting Transport and Electrostatic Properties of Selectively Fluorinated Alkanethiol Monolayers with Embedded Dipoles" R. C. Bruce; L. using temperature responsive hydrogel for integrin-mediated mechanical force stimulation [63]. Associated Projects: University of Kentucky: Nutrition and Superfund Chemical Toxicity The prototype N-isopropylacrylamide hydrogel cross-linked with di (ethylene glycol) divinyl ether p (NIPAAm-co-DEGDVE) swells at low temperature and collapses above the lower critical solution temperature (LCST), ∼29 °C in a buffer.
