Comparison of carboxybetaine with sulfobetaine polyaspartamides: Nonfouling properties, hydrophilicity, cytotoxicity and model nanogelation in an inverse miniemulsion

Journal of Applied Polymer Science, 2021
AbstractZwitterionic polymers are promising non‐fouling materials widely used for surface modification. Here, we report the synthesis of zwitterionic polyaspartamides bearing carboxybetaine and sulfobetaine prepared via combining the ring‐opening reaction of polysuccinimide with 3‐(dimethylamino)‐1‐propylamine and the reaction of the formed tertiary ...

Hydrophilic Fluorescent Nanogel Thermometer for Intracellular Thermometry

Journal of the American Chemical Society, 2009
The first methodology to measure intracellular temperature is described. A highly hydrophilic fluorescent nanogel thermometer developed for this purpose stays in the cytoplasm and emits stronger fluorescence at a higher temperature. Thus, intracellular temperature variations associated with biological processes can be monitored by this novel ...

Hydrophilicity/Hydrophobicity Reversable and Redox-Sensitive Nanogels for Anticancer Drug Delivery

Molecular Pharmaceutics, 2015
Long circulation in the blood, efficient cellular internalization, and intracellular drug release in the tumor cells are major challenges in the development of ideal anticancer drug delivery systems. In this paper, hydrophilicity/hydrophobicity reversable and redox-sensitive poly(oligo(ethylene glycol) methacrylates-ss-acrylic acid) (P(OEGMAs-ss-AA ...

Selective Release of Hydrophobic and Hydrophilic Cargos from Multi-Stimuli-Responsive Nanogels

ACS Applied Materials & Interfaces, 2016
Highly stable multi-stimuli-responsive nanogels for selective release of simultaneously encapsulated hydrophobic and hydrophilic cargos in a spatiotemporally controlled manner are demonstrated here. The nanogel is composed of hydrophilic pH- and thermoresponsive poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) and hydrophobic photocleavable o ...

Design of hydrophilic photocleavage o-nitrobenzyl acrylate-modified nanogels with outstanding biocompatibility prepared by RAFT polymerization for drug carrier

European Polymer Journal, 2020
Abstract Three kinds of hydrophilic photocleavage o-nitrobenzyl acrylate-modified nanogels with different particle size and narrow particle size distribution (1.8–0.24) were designed and synthesized by reversible addition-fragmentation chain transfer radical (RAFT) polymerization based on methoxy polyethylene glycol methacrylate (MPEGMA) and UV-light

Covalent-bonded immobilization of enzyme on hydrophilic polymer covering magnetic nanogels

Microporous and Mesoporous Materials, 2008
Abstract A new mesoporous support, hydrophilic polymer covering magnetic nanogels containing reactive carboxyl groups, was obtained by photochemical in situ polymerization. The enzyme α-chymotrypsin (CT), a model for protein or esters hydrolysis, was anchored to the support by 1-ethyl-3-(3-dimethylaminepropyl) carbodiimide (EDC) activation.

Abstract 3099: pH-regulated hydrophilicity/hydrophobicity-, surface charge-reversible and redox sensitive nanogels for anticancer drug delivery

Cancer Research, 2017
Abstract Long circulation in blood, enhanced tumor accumulation and penetration, efficient cellular internalization and intracellular drug release are major challenges in the development of ideal anticancer drug delivery systems. Although several strategies have been reported to improve therapeutic efficacy, they mainly meet one or a few
