Salbutamol sulphate is a sympathomimetic amine having a rather short plasma half-life. Aiming to achieve sustained release of this drug through microencapsulation, the coacervation method with a 1:1 core-shell ratio was used. In vitro release rate experiments were performed on the microcapsules prepared using ethyl cellulose as the coating agent and ...

A system of nomenclature is proposed whereby microcapsules are named after their 'core', 'wall' or 'both core and wall', as may be desired. The proposed nomenclature provides short descriptive names, and eliminates the need for lengthy phrases often used in the microencapsulation literature.

SummaryPhotosensitive microcapsules that reversibly switch upon visible light irradiation are attractive targets for drug delivery, fragrance release and pesticide delivery. In this study we report the development of visible light triggered microcapsules and demonstrate the concept of protection and remote release of a model, non‐toxic perfume oil ...

Science, 1964
Simple methods have been developed for encapsulating aqueous solutions of protein within polymer membranes. Stable microcapsules 1 to 100 μ in diameter, with semipermeable membranes, can be made by depositing polymer around emulsified aqueous droplets, either by interfacial coacervation or by interfacial polycondensation.

Permeation of Macromolecules into Polyelectrolyte Microcapsules
Biomacromolecules, 2002Polyelectrolyte microcapsules (PEMCs) have been prepared by coating red blood cells with the polyelectrolytes poly(styrenesulfonate), poly(allylamine hydrochloride), and dextran sulfate applying the layer-by-layer technique with subsequent dissolution of the core.

Superlubricity, a lubricating state in which the coefficient of friction (COF) is smaller than 0.01, has been achieved at the macroscale in a variety of aqueous solutions and oils, as well as two-dimensional (2D) and carbon materials; nevertheless, it has been rarely realized with polymer composites.

Polymer Microcapsules with “Foamed” Membranes
Langmuir, 2007This article describes the preparation of capsules displaying craters at their surfaces and independent holes inside their membranes. These poly(methylmethacrylate) capsules of 20 to 200 microm diameter are prepared by a solvent evaporation process and typically contain a dispersant, polyvinyl alcohol, and an excipient, namely, a fatty acid ...
