Thermoresponsive Gelatin Nanogels

ACS Macro Letters, 2014
We present a novel tunable thermoresponsive gelatin nanogel that shows a volume transition at ∼32 °C. A thermally induced volume reduction of more than 30× is observed due to the helix to random coil transition of gelatin chains confined in the nanogels. The physical process and key factors influencing thermoresponsive properties are investigated using

Thermoresponsive polysaccharides with tunable thermoresponsive properties via functionalisation with alkylamide groups

Carbohydrate Polymers, 2021
Polysaccharides have been used widely in many industries, from food technology and mining to cosmetics and biomedical applications. Over recent years there has been growing interest in the development of responsive polysaccharides with unique and switchable properties, particularly systems that display lower-critical solution temperatures (LCSTs ...

Thermoresponsive copolymer microgels

Journal of Materials Chemistry B, 2013
Colloidal aqueous microgels have attracted notable attention due to their possible applications in both polymer chemistry and the (bio)material sector. Due to their soft internal network structure and their response to different external stimuli, they are suitable as carrier systems for different kinds of molecules (e.g.

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.
