Thermoresponsive Gold Nanoparticles with Positive UCST‐Type Thermoresponsivity

Macromolecular Chemistry and Physics, 2014
Trithiocarbonate end‐functionalized poly(N‐acryloylglycinamide) (PNAGA), synthesized via reversible addition–fragmentation transfer (RAFT) polymerization of different molecular weights, is grafted onto gold nanoparticles (AuNPs) by ligand exchange in phosphate‐buffered saline.

Thermoresponsive hydroxybutylated starch nanoparticles

Carbohydrate Polymers, 2019
Starch nanoparticles (SNPs) have been explored as promising new environmentally friendly materials for over a decade. On the other hand, thermoresponsive SNPs, which have potential novel applications in medicine, food and composites, have not yet been reported. Here we report the preparation and characterization of thermoresponsive SNPs. Hydroxypropyl (

Thermoresponsive amperometric glucose biosensor

Biointerphases, 2015
The authors report on the fabrication of a thermoresponsive biosensor for the amperometric detection of glucose. Screen printed electrodes with heatable gold working electrodes were modified by a thermoresponsive statistical copolymer [polymer I: poly(ω-ethoxytriethylenglycol methacrylate-co-3-(N,N-dimethyl-N-2-methacryloyloxyethyl ammonio ...

Engineering thermoresponsive polymeric nanoshells

Biomaterials, 2009
This study describes a family of hollow nanoscale constructs able to display a large and reversible change in size, within a narrow temperature interval. These thermoresponsive nanostructures are generated by crosslinking functionalized amphiphilic molecules, such as poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO ...

Thermoresponsive microgel-based materials

Chemical Society Reviews, 2009
With the continued development of thermoresponsive colloidal hydrogel particles, a number of groups have begun to exploit their properties to create dynamic materials self-assembled from those components. The fundamental details of how those building blocks are assembled, the component functionality, and the geometry or length-scales present in the ...

Reactive thermoresponsive copolymer scaffolds

Chemical Communications, 2010
Thermoresponsive copolymer scaffolds containing reactive aldehyde functions were prepared and a selection of organic residues conjugated to these copolymer scaffolds through oxime/hydrazone formation. The conjugation of hydrophobic residues affords copolymers whose lower solution critical temperatures are in most cases higher than that of the parent ...

Thermoresponsive Poly(2‐oxazine)s

Macromolecular Rapid Communications, 2011
AbstractThe monomers 2‐methyl‐2‐oxazine (MeOZI), 2‐ethyl‐2‐oxazine (EtOZI), and 2‐n‐propyl‐2‐oxazine (nPropOZI) were synthesized and polymerized via the living cationic ring‐opening polymerization (CROP) under microwave‐assisted conditions. pEtOZI and pnPropOZI were found to be thermoresponsive, exhibiting LCST behavior in water and their cloud point ...

Thermoresponsive Dendronized Polymers

Macromolecules, 2008
The efficient synthesis of high molar mass, first- (G1) and second-generation (G2) dendronized polymethacrylate derivatives PG1 and PG2, respectively, and their thermoresponsive properties in aqueous solution are described. All dendrons are branched 3-fold and were synthesized on the multigram scale using gallic acid as branching point and tri(ethylene

Thermoresponsive Photonic Crystals

The Journal of Physical Chemistry B, 2000
Hydrogel nanoparticles that undergo volume phase transitions in response to changes in temperature and pH have been used to assemble colloidal crystal gels with environmentally tunable optical properties. When monodisperse, ∼210-nm-diameter hydrogel particles are close-packed via centrifugation, the resultant viscous polymer pellet displays a bright ...
