PVP and NIPAM-coated CsPbBr 3 NCs are highly luminescent and show excellent stability. These monodispersed NCs were successfully tested as a fluorescent probe for live cell imaging resulting in...

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....

2020年11月15日 · Time-lapse NMR studies provide insight into the molecular changes in the P (NIPAm- co -MAA) hydrogel during temperature collapse and show how the presence of negatively charged and highly hydrated carboxylate groups impacts collapse at …

2024年2月15日 · The successful polymerization of NIPAM to the CTA-PEG-CTA was confirmed using gel permeation chromatography (GPC) and 1 H nuclear magnetic resonance (NMR) spectroscopy. 1 H-NMR spectrum of tri-block PNIPAM–PEG–PNIPAM copolymer showed methine (CH) and methyl (CH3) proton resonance peaks of PNIPAM unit at δ = 4.02 and 1.13 ppm, respectively ...

In this study, Poly (N-isopropyl acrylamide) (PNIPAAm), a temperature-sensitive injectable hydrogel, was selected as a minimally invasive scaffold to accommodate, carry, and release of...

2017年5月5日 · NMR studies of the structure and dynamics of polymer gels based on N-Isopropylacrylamide (NiPAAm) and methacrylic acid (MAA)

2001年9月30日 · To study the effect of charged polymer segments on the phase transition, the temperature dependent properties of PNIPAM and of a charged PNIPAM-copolymer, containing 10% carboxylic groups, are investigated in solution. Experiments are performed by 1H spectra and PFG-NMR diffusion measurements at different polymer concentrations.

2012年4月17日 · Our results showed that both optical and NMR approaches have acceptable sensitivity and accuracy for dose determination with NIPAM gel. However, for optical reading of the gel, utilization of an optimum optical wavelength is recommended.

2021年11月12日 · A microscopic understanding of the internal structure and dynamics of poly (N -isopropylacrylamide) (PNIPAM) chains, in microgel colloids, is developed using deuterium NMR (2 H NMR) to study deuterated PNIPAM suspensions as functions of temperature and pressure for four cross-linker molar fractions (f).
