The first fluorescent cyclophane with mechano- and thermoresponsive solid-state fluorescence characteristics is reported. The new cyclophane comprises two 9,10-bis(phenylethynyl)anthracene moieties that are bridged by tetraethylene glycol spacers. The stimuli-responsiveness is based on molecular assembly changes.
The catalytic performance of thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) functionalized at the terminal position with randomly methylated β-cyclodextrin was demonstrated by the aqueous Rh-catalysed hydroformylation of higher olefins.
Different biomolecules have been identified in bacterial pathogens that sense changes in temperature and trigger expression of virulence programs upon host entry. However, the dynamics and quantitative outcome of this response in individual cells of a population, and how this influences pathogenicity are unknown. Here, we address these questions using a thermosensing virulence regulator of an i...
Thermoresponsive behavior of polymers in aqueous solutions has been widely studied and utilized various applications. However, the fundamental understanding on use oil soluble non-aqueous solutions...
Thermoresponsive polymers based on oligo(ethylene glycol) (OEG) methyl ether methacrylate monomers from unimers to micelles precipitation.
In this study the properties of poly(D,L-lactide-co-glycolide) (PLGA) dispersions containing a thermoresponsive cationic copolymer were investigated. The PLGA dispersions were prepared by interfacial deposition in aqueous solution and were rendered thermoresponsive by addition of a cationic poly(N-isopropyl acrylamide) (PNIPAm) graft copolymer. The copolymers used had the general composition PD...
Rapid cell growth and rapid recovery of intact cultured cells are an invaluable technique to maintain the biological functions and viability of cells. To achieve this goal, thermoresponsive polystyrene (PS) nanofibrous mat was fabricated by electrospinning of PS solution, followed by the graft polymerization of thermoresponsive poly(N-isopropylacrylamide)(PIPAAm) on PS nanofibrous mats. Image a...
Recently, with the development of smart polymers, research has looked to using thermoresponsive polymers as cell culture substrates. These novel surfaces allow the cultivation of cells without enzymes using the thermoresponsive phase transition property of poly(N-isopropylacrylamide) (PNIPAAm). However, this requires expensive techniques to generate a sufficiently thin film that allows cell adh...
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.
