Hollow porous silica microspheres may be applicable as containers for the controlled release in drug delivery systems (DDS), foods, cosmetics, agrochemical, textile industry, and in other technological encapsulation use. In order to control the surface morphological properties of the silica microspheres,...
In conclusion, mesoporous silica microspheres were prepared using the microwave assisted hydrothermal technique. Possessed high specific surface area 340 m2/g and appropriate pore diameter (20–40 nm). It is doubtlessly an excellent carrier for immobilized lipase. The optimum pH and temperature for imm...
(lending it an enormous external surface area), the size of the spheres themselves can be controlled during the preparation process. Fumed silica exhibits thixotropic properties and is typically used as a dessicant, thickening and anti-caking agent, and stabilizer in pharmaceuticals, cosmetics, paints...
prevent sedimentation during molding, and decrease the release rate. Colloidal silicon dioxide is also used as an adsorbent during the preparation of wax microspheres; as a thickening agent for topical preparations; and has been used to aid the freeze-drying of nanocapsules and nanosphere suspensions...
seen for the exclusion of nonpolar alcohols from the highly charged DNA and of salts and small polar solutes from the hydrophobically modifiedcellulose[40]. The exclusion magnitudes for different salts follow the Hofmeister series, which has long been thought to be connected with water structuring[...
