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 ...

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 polymers in liquid chromatography

Anal. Methods, 2012
In liquid chromatography, ‘reversed’ phase (RP) HPLC accounts for the vast majority of analyses concerning the separation of biomolecules. However, the typical usage of organic mobile phases as eluents associated with this technique has drawbacks in certain applications due to the possible denaturation of biocompounds, including other concerns related ...

Microalgae aggregation induced by thermoresponsive polymers

Bioresource Technology
Algal biomass harvesting is one of key technical hurdles impeding the commercialization of algae-based biorefinery. The goal of this work is to develop an innovative technology for algae cell harvesting. Thermoresponsive polymers (TRPs) such as poly(N-isopropylacrylamide) (PNIPAM) and its derivatives were studied on their properties and potential ...

Patterned Immobilization of Thermoresponsive Polymer

Langmuir, 1997
The thermoresponsive polymer poly(N-isopropylacrylamide) was immobilized in a specific pattern on a polystyrene matrix by photolithography. N-Isopropylacrylamide was copolymerized with acrylic acid. The copolymer was coupled with azidoaniline. The low critical solution temperature of the copolymer was lowered by incorporation of azidophenyl groups. The

Magnetic Nanoparticles Encapsulated Within a Thermoresponsive Polymer

Journal of Nanoscience and Nanotechnology, 2009
This study describes a facile two-step approach to modify the surface of nanoparticles, thereby imparting a core-shell structure to the system. The core consists of magnetic nanoparticles and the shell is composed of thermoresponsive hydroxypropyl cellulose, using a coupling agent to covalently bind the core to the shell.
