The behavior of hydrophobic-core/hydrophilic-shell structured microgels at an interface: from Mickering emulsion to colloidosomes with dual-level controlled permeability

Abstract

The release of model drug FITC-Dex from colloidosomes was examined in selected media and the controllable release was achieved by adjusting the pH (coarse level) and the ratio of the shell to core in the microgels (fine level).

Synergistic Interactions of Plant Protein Microgels and Cellulose Nanocrystals at the Interface and Their Inhibition of the Gastric Digestion of Pickering Emulsions

“…Pickering emulsions stabilized by biocompatible particles have recently aroused significant research interest owing to their extraordinary stability against coalescence due to their high particle desorption energies of the order of several thousands k B T (where k B is the Boltzmann constant and T is temperature) as opposed to <5 k B T for surfactant-stabilized emulsions and a few hundred k B T for biopolymer-stabilized emulsions. − Of more interest here is that emulsions are stabilized either by rigid solid particles via the Pickering stabilization mechanism or soft solid particles, which are often referred to as Mickering emulsions , that have been used as novel vehicles to modulate lipid digestion in the human gastrointestinal (GI) tract to allow the delivery of lipid soluble active compounds for pharmaceutical and food applications. This is largely attributed to the ability of these particles to be resistant against competitive displacement by surface-active agents in human physiology such as bile salts .…”

Stimuli-Responsive Microgels and Microgel-Based Systems: Advances in the Exploitation of Microgel Colloidal Properties and Their Interfacial Activity

“…Hence, in contrast to conventional hard particles, these microgels can exhibit unique interfacial behavior when located at fluid or solid interfaces without necessarily being amphiphilic. Further, the stability of the microgel-stabilized emulsions can be tuned by taking advantage of the stimuli-responsive characteristic of microgels [ 23 ]. Due to the tunable emulsion properties, these microgel-based emulsions are useful in biomedicine, catalysis, food products, and cosmetics [ 24 , 25 ].…”

Optimal Design and Implementation of a Fast Start Scheme for a High Real-Time Embedded Electromechanical Control System

“…It appears in the form of menu in the shell interface of the terminal, and it can extract the default value in the .config file and display it in the configuration menu. After the kernel is started, it can be dynamically loaded into the system through the kernel module [22]. When the module is loaded into the kernel, insmod is used to complete the task.…”
