Sol-gel chemistry encapsulates active molecules by building a porous glass or ceramic oxide matrix) around them. A sol-gel solution is created by combining a ceramic precursor, the active ingredient that is to be encapsulated, and water. As soon as the water is added, polymerisation starts and a gel is created.
CeramiSphere combines sol-gel chemistry with emulsion chemistry, and has advantages over other methods, some of which require the use of high temperatures, or suffer from relatively low production yield, surface segregation and size limitations.
Sol-gel emulsions are more effective because they enable the production of either micro or nanoparticles with homogenous distribution activity, and permit ambient temperature processing, which is necessary for handling temperature-sensitive biological agents.
Independent control of the size and release rate can be readily achieved, and emulsion polymerisation is easily scalable due to the compartmentalisation of the reactions inside the emulsion droplets.
