Production of Biocompatible Aerogel Microparticles

Production of Spherical Aerogel Microparticles by Supercritical Extraction of Emulsion

Due to high surface area, low density, open pore structure and excellent insulation properties aerogels were intensively investigated in the past decades for diverse range of applications. The state of the art of aerogel production by supercritical drying is to produce monolithic aerogel, where the sol is aged in molds and dried by extraction with supercritical CO2. Aerogels in form of spherica...

Processing of Organic Microparticles during Capture in Aerogel

Introduction: Hypervelocity capture in space has long been established in aerogel targets [1]. Since the first laboratory demonstration of capture [2] aerogel collectors have been flown in space for extended periods on several missions. Particles during hypervelocity capture can be significantly ablated, altering the size and structure of the projectile, potentially biasing any subsequent analy...

Biocompatible polymeric microparticles produced by a simple biomimetic approach.

The use of superhydrophobic surfaces to produce polymeric particles proves to be biologically friendly since it entails the pipetting and subsequent cross-linking of polymeric solutions under mild experimental conditions. Moreover, it renders encapsulation efficiencies of ∼100%. However, the obtained particles are 1 to 2 mm in size, hindering to a large extent their application in clinical tria...
