Cytotoxic evaluation of N-isopropylacrylamide monomers and temperature-sensitive poly(N-isopropylacrylamide) nanoparticles

Journal of Nanoparticle Research, 2008
The objective of this research project is to investigate the biocompatibility of N-isopropylacrylamide (NIPAAm) monomers and poly(N-isopropylacrylamide) (PNIPAAm) nanoparticles in vitro. PNIPAAm nanoparticles of different sizes were synthesized and characterized by transmission electron microscopy and dynamic light scattering.

Thermogelation properties of poly(N-isopropylacrylamide) – block – poly(ethylene glycol) – block – poly(N-isopropylacrylamide) triblock copolymer aqueous solutions

Reactive and Functional Polymers, 2010
Abstract Low polydispersity PNIPAM–PEG–PNIPAM triblock copolymers with PEG blocks of 1–6 kDa and PNIPAM chains of 5–30 kDa were synthesized and their thermogelation behavior in aqueous solution as a function of their composition and block length was investigated for the first time. DSC, dynamic rheometry and the tube inverting method were employed to

Vibrational heat capacity of Poly(N-isopropylacrylamide)

Polymer, 2015
Abstract The heat capacity of poly(N-isopropylacrylamide) (PNIPA) has been measured from (1.8–460) K using a quantum design PPMS (Physical Property Measurement System) and differential scanning calorimeters. The low-temperature experimental heat capacity below the glass transition temperature 415 K (141.85 °C) was linked to the vibrational molecular ...

The electrophoresis of poly( N -isopropylacrylamide) microgel particles

Colloid & Polymer Science, 2000
The electrophoretic mobility of a poly(N-isopropylacrylamide) microgel containing carboxylic groups has been measured as a function of the ionic strength, between 0.1 and 100 mM NaCl, over the temperature range 2545 ∘C. The mobility data obtained have been evaluated using different models, including the porous-sphere, the soft-plate and the soft-sphere

Photopolymerization synthesis of poly(N-isopropylacrylamide) hydrogels

Journal of Applied Polymer Science, 1997
Poly(N-isopropylacrylamide) (NIPAAm) gels were formed by photopolymerization of NIPAAm in the absence of a crosslinker using a water solvent at 25°C. Factors affecting formation were the wavelength region of irradiated light, the type of photoinitiators, and the concentrations of the photoinitiator and monomer.
