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.

Hollow Thermoresponsive Microgels

Small, 2005
AbstractThermoresponsive poly(N‐isopropyl acrylamide) (pNIPAm) microgels possessing a hollow structure have been synthesized from core–shell nanoparticles upon oxidation of the particle core, followed by removal of the produced polymer segments by centrifugation.

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 chiral plasmonic nanoparticles

Nanoscale, 2022
Poly(N-isopropylacrylamide) (PNIPAM) has been used to modify chiral plasmonic nanoparticles. The thermoresponsive studies reveal the impact of achiral dielectric nanoenvironment on chiral plasmonic responses.

Thermoresponsive Corannulene

European Journal of Organic Chemistry, 2017
We demonstrate herein that corannulene, a bowl‐shaped polycyclic aromatic hydrocarbon, can assemble into larger supramolecular structures in water through a change in the solution temperature. This property is invoked through a simple five‐fold symmetric substitution of the corannulene nucleus with triethylene glycol units.

Thermoresponsive dendritic oligoethylene glycols

Physical Chemistry Chemical Physics, 2022
Dendritic oligoethylene glycols show topological structure-dependent thermoresponsiveness to intriguingly encapsulate guests and there is a balance between the dehydrated and the hydrated molecules at elevated temperatures.

Backbone-Thermoresponsive Hyperbranched Polyethers

Journal of the American Chemical Society, 2006
A new type of materials, the backbone-thermoresponsive hyperbranched polyether, was successfully synthesized by proton-transfer polymerization of 1,4-butanediol diglycidyl ether and various triols, and the lower critical solution temperature (LCST) values can be readily adjusted from 19.0 to 40.3 degrees C by changing the hydrophilic/hydrophobic ...

Thermoresponsive Hydrogels for Cellular Delivery

Therapeutic Delivery, 2012
The delivery of living cells into a host body has emerged as a promising approach to treating a variety of different diseases and for tissue repair. However, one of the major obstacles for clinical success is to deliver the cells to the target tissue without losing control of cell fate and function after transplantation.

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 Supramolecular Dendronized Polymers

Chemistry – An Asian Journal, 2011
AbstractCombining the concepts of supramolecular polymers and dendronized polymers provides the opportunity to create bulky polymers with easy structural modification and tunable properties. In the present work, a novel class of side‐chain supramolecular dendronized polymethacrylates is prepared through the host–guest interaction.
