Biodistribution of a radiolabelled thermoresponsive polymer in mice

Applied Radiation and Isotopes, 2010
Drug delivery systems based on thermoresponsive polymers might serve as suitable carriers for local radiotherapy. We have, therefore, designed and synthesized a radioiodine-labellable thermoresponsive polymer. The polymer was synthesized by copolymerization of N-isopropylacrylamide with N-methacryloyl tyrosinamide in tetrahydrofuran, and then labelled ...

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.

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 ...

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 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 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 Coiled-Coil Peptide–Polymer Grafts

Bioconjugate Chemistry, 2023
Alkyl halide side groups are selectively incorporated into monodispersed, computationally designed coiled-coil-forming peptide nanoparticles. Poly[2-(dimethylamino)ethyl methacrylate] (PDMAEMA) is polymerized from the coiled-coil periphery using photoinitiated atom transfer radical polymerization (photoATRP) to synthesize well-defined, 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 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 ...
