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

New directions in thermoresponsive polymers

Chemical Society Reviews, 2013
Interest in thermoresponsive polymers has steadily grown over many decades, and a great deal of work has been dedicated to developing temperature sensitive macromolecules that can be crafted into new smart materials. However, the overwhelming majority of previously reported temperature-responsive polymers are based on poly(N-isopropylacrylamide ...

Confined Microenvironments from Thermoresponsive Dendronized Polymers

Macromolecular Rapid Communications, 2020
AbstractConfined microenvironments in biomacromolecules arising from molecular crowding account for their well‐defined biofunctions and bioactivities. To mimick this, synthetic polymers to form confined structures or microenvironments are of key scientific value, which have received significant attention recently.

Thermoresponsive polymer-stabilized silver nanoparticles

Journal of Colloid and Interface Science, 2008
Silver nanoparticles (Ag NPs) stabilized by a thermoresponsive polymer, poly(N-isopropylacrylamide) (PNIPAM), have been synthesized by the reduction of silver ions with NaBH(4) in aqueous solutions. The obtained Ag NPs are very stable at room temperature due to the extended coil conformation of the PNIPAM chain at temperatures below its volume phase ...

Thermoresponsive Synthetic Polymer–Microtubule Hybrids

Langmuir, 2013
Thermoresponsive hybrids consisting of synthetic polymers and microtubules (MTs), i.e., assemblies of tubulins, were prepared by bonding MTs covalently to a few reactive units in a macromolecular strand. The hybrids exhibited the gel/sol transition because of the "assembling of tubulins to MTs/disintegrating of MTs to tubulins" by the temperature ...

Nanoscale Inhomogeneities in Thermoresponsive Polymers

Macromolecular Rapid Communications, 2012
AbstractThis article highlights the occurrence and nature of nanoscale inhomogeneities in thermoresponsive polymers and focuses on different experimental techniques for their observation and characterization. Such inhomogeneities can be regarded as nanoscopic domains of collapsed polymer segments (or of a small number of unimers), which provide a ...

Thermoresponsive Polymers Based on Tertiary Amine Moieties

Macromolecular Rapid Communications, 2021
AbstractThermoresponsive polymers exhibiting unique reversible phase transition properties in aqueous solution in response to temperature stimuli have been extensively investigated. In the past two decades, thermoresponsive polymers based on tertiary amine moieties have achieved considerable progress and become an important family of thermoresponsive ...

DNA Hybridization in Thermoresponsive Polymer Nanoparticles

ChemPhysChem, 2010
AbstractWe achieve very high hybridization efficiencies by using a new method to immobilize DNA strands on the surface of thermoresponsive polymer nanoparticles. Hybridization efficiencies of about 70 % are obtained between the DNA immobilized in the particles and a complementary strand in solution, even at very low ionic strengths (1 mM).

Thermoresponsive polymer-peptide/protein conjugates

Progress in Polymer Science, 2017
Abstract This review is focused on recent achievements in the covalent attachment of biological entities, such as oligopeptides, proteins and enzymes, to thermoresponsive synthetic polymers and the influence of conjugation on the properties of macromolecules.
