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.

Thermoresponsive Polymer Micelles as Potential Nanosized Cancerostatics

Biomacromolecules, 2015
An effective chemotherapy for neoplastic diseases requires the use of drugs that can reach the site of action at a therapeutically efficacious concentration and maintain it at a constant level over a sufficient period of time with minimal side effects.

Thermoresponsive polymer-modified microfibers for cell separations

Acta Biomaterialia, 2017
Thermoresponsive polymer-modified microfibers were prepared through electrospinning of poly(4-vinylbenzyl chloride) (PVBC) and subsequent surface-initiated atom transfer radical polymerization for grafting poly(N-isopropylacrylamide) (PIPAAm). Electrospinning conditions were optimized to produce large-diameter (20μm) PVBC microfibers.

Switching between Polymer Architectures with Distinct Thermoresponses

Macromolecular Rapid Communications, 2017
Thermoresponsive linear polymers and their corresponding aggregates or nanogels typically show similar thermoresponsive profiles. In this study, the authors demonstrate reversible chemical switching between linear polymers and their cross-linked nanogels.

Thermal Switching of Thermoresponsive Polymer Aqueous Solutions

ACS Macro Letters, 2017
Thermal switches are of great importance to thermal management in a wide variety of applications. However, traditional thermal switches suffer from being large and having slow transition rates. To overcome these limitations, we took advantage of abrupt second-order phase transitions in thermoresponsive polymer aqueous solutions to enable fast thermal ...

Thermoresponsive AuNPs Stabilized by Pillararene‐Containing Polymers

Macromolecular Rapid Communications, 2015
Pillararene‐containing thermoresponsive polymers are synthesized via reversible addition–fragmentation chain transfer polymerization using pillararene derivatives as the effective chain transfer agents for the first time. These polymers can self‐assemble into micelles and form vesicles after guest molecules are added.
