Multilayer Hydrogel Capsules of Interpenetrated Network for Encapsulation of Small Molecules

Langmuir, 2018
We report on a facile capsule-based platform for efficient encapsulation of a broad spectrum of hydrophilic compounds with molecular weight less than 1000 g mol-1. The encapsulated compounds extend from low-molecular-weight anionic Alexa Fluor 532 dye and cationic anticancer drug doxorubicin (DOX) to fluorescein isothiocyanate-dextrans with Mw ranging ...

Effect of SiO₂ on Immobilization of Metals and Encapsulation of a Glass Network in Slag [PDF]

Journal of the Air & Waste Management Association, 2003
The final disposal of ash from an incinerator is of special concern because of the possibility of its releasing toxic substances. Melting/vitrification has been regarded as a prospective technology of ash treatment. The object of this investigation was to evaluate the effect of silica (SiO2) addition on the immobilization of hazardous metals and the ...

Enhanced activity of vancomycin by encapsulation in hybrid magnetic nanoparticles conjugated to a cell-penetrating peptide.

Nanoscale, 2020
We describe a novel antibiotic delivery system based on magnetic nanoparticles (NPs) conjugated to a cell-penetrating peptide (CPP). Silica-coated iron oxide NPs were produced via a co-deposition method, and coated by a polyvinyl alcohol (PVA) polymeric ...

Micro-Encapsulation and Tuning of Biomolecular Unit Cell Networks

Volume 2: Mechanics and Behavior of Active Materials; Integrated System Design and Implementation; Bioinspired Smart Materials and Systems; Energy Harvesting, 2014
The goal of our research is to fabricate an autonomic material system that provides compartmentalization and multi-bilayer networks for enabling collective biomolecular functionality, as is found in living cells and tissues. The material system is based on biomolecular unit cells, which consist of synthetic lipid bilayers formed at the interfaces of ...

Encapsulation of Enzymes in Metal–Phenolic Network Capsules for the Trigger of Intracellular Cascade Reactions

Langmuir, 2021
Nanoengineered capsules encapsulated with functional cargos (e.g., enzymes) are of interest for various applications including catalysis, bioreactions, sensing, and drug delivery. Herein, we report a facile strategy to engineer enzyme-encapsulated metal-phenolic network (MPN) capsules using enzyme-loaded zeolitic imidazolate framework nanoparticles ...

High-internal-phase emulsions (HIPEs) for co-encapsulation of probiotics and curcumin: enhanced survivability and controlled release.

Food & Function, 2020
Synergistic biological activities of probiotics and curcumin can be achieved based on the gut-brain axis. However, it is still a challenge for utilizing both of them in actual food products due to their high sensitivity to environmental conditions.

Physical encapsulation of droplet interface bilayers for durable, portable biomolecular networks

Lab on a Chip, 2010
Physically-encapsulated droplet interface bilayers are formed by confining aqueous droplets encased in lipid monolayers within connected compartments of a solid substrate. Each droplet resides within an individual compartment and is positioned on a fixed electrode built into the solid substrate.

Interpenetrating polymer networks of alginate and polyethylene glycol for encapsulation of islets of Langerhans

Journal of Microencapsulation, 2000
A mixture of alginate and polyethylene glycol acrylate was investigated as a system for the encapsulation of islets of Langerhans. This system showed dual crosslinkability: the alginate was ionically crosslinked by multivalent cations, and the PEG was covalently crosslinked by photoactivated free radical polymerization.

Modeling lipid-encapsulated microbubbles using transient network theory

The Journal of the Acoustical Society of America, 2019
Encapsulated microbubbles (EMBs) are widely used to enhance contrast in ultrasound sonography and are finding increasing use in biomedical therapies such as drug/gene delivery and tissue ablation. EMBs consist of a gas core surrounded by a stabilizing shell made of various materials, including polymers, lipids, and proteins. Lipid-coated EMBs present a

Encapsulation of Bromothymol Blue into a Polysiloxane Network Matrix in Presence of Surfactants

Journal of Dispersion Science and Technology, 2011
Bromothymol blue (BTB) pH indicator was encapsulated into polysiloxane network using the sol-gel process. Transparent monolithic disks of entrapped BTB were obtained in the presence of cetyl trimethyl ammonium bromide (CTAB) or dodecyl dimethyl amino oxide (Genaminox LA, GLA) surfactant.
