Hydrophilic Fluorescent Nanogel Thermometer for Intracellular Thermometry
Journal of the American Chemical Society, 2009The 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, 2015Long 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, 2016Highly 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 ...

Microgels and Nanogels for the Delivery of Poorly Water-Soluble Drugs.
Molecular Pharmaceutics, 2022While microgels and nanogels are most commonly used for the delivery of hydrophilic therapeutics, the water-swollen structure, size, deformability, colloidal stability, functionality, and physicochemical tunability of microgels can also offer benefits ...

Covalent-bonded immobilization of enzyme on hydrophilic polymer covering magnetic nanogels
Microporous and Mesoporous Materials, 2008Abstract 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.
