Poly(N-isopropyl acrylamide)–poly(ethylene glycol)–poly(N-isopropyl acrylamide) as a thermoreversible gelator for topical administration

Assessment of cytotoxicity of (N-isopropyl acrylamide) and Poly(N-isopropyl acrylamide)-coated surfaces

Poly(N-isopropyl acrylamide) (pNIPAM) is one of the most popular stimulus-responsive polymers for research. It is especially of great interest in the field of tissue engineering. While it is known that the NIPAM monomer is toxic, there is little conclusive research on the cytotoxicity of the polymer. In this work, the relative biocompatibility of the NIPAM monomer, pNIPAM, and pNIPAM-coated sub...

N-isopropyl-acrylamide Conjugated Polyglycerol as a Delivery Vehicle for in Vitro Sirna Transfection

Analysis using size exclusion chromatography of poly(N-isopropyl acrylamide) using methanol as an eluent

Size Exclusion Chromatography is traditionally carried out in either aqueous or non-polar solvents. A system to present molar mass distributions of polymers using methanol as a mobile phase is presented. This is shown to be a suitable system for determining the molar mass distributions poly(N-isopropylacrylamide)s (PNIPAM); a polymer class that is often difficult to analyze by size exclusion ch...

Monodisperse Nanoparticles of Poly(ethylene glycol) Macromers and N-Isopropyl Acrylamide for Biomedical Applications

Poly(ethylene glycol)-based nanoparticles have received significant attention in the field of biomedicine. When they are copolymerized with pHor temperature-sensitive comonomers, their small size allows them to respond very quickly to changes in the environment, including changes in the pH, ionic strength, and temperature. In addition, the high surface-to-volume ratio makes them highly function...

Composite Films Based on Aligned Carbon Nanotube Arrays and a Poly(N-Isopropyl Acrylamide) Hydrogel

Hybrid materials based on carbon nanotubes (CNTs) and polymers, which integrate the unique characters and functions of these two types of components, have shown improved properties and potential applications in many fields. However, the aggregation of CNTs in the polymer matrix is always a big problem in the preparation of composites. It has been proven that using CNT arrays instead of random C...
