Carminic Acid Linked to Silica Nanoparticles as Pigment/Antioxidant Bifunctional Excipient for Pharmaceutical Emulsions

Bifunctional hairy silica nanoparticles as high-performance additives for lubricant

Bifunctional hairy silica nanoparticles (BHSNs), which are silica nanoparticles covered with alkyl and amino organic chains, were prepared as high-performance additives for lubricants. Compared with hairy silica nanoparticles covered by a single type of organic chain, binary hairy silica nanoparticles exhibit the advantages of both types of organic chains, which exhibit excellent compatibility ...

Potential aspects of chitosan as pharmaceutical excipient.

Interest in use of the polysaccharide chitosan as a pharmaceutical excipient by different dose routes and for a number of applications is not new but it still does not appear to be present in any marketed drugs. Also a novel excipient in a new formulation requires a lot of safety consideration. Published literature showed that chitosan has low oral toxicity and prior human exposure has occurred...

Phase-Selective Catalysis in Emulsions Stabilized by Janus Silica- Nanoparticles

Metal-containing Janus particles are used as interfacial catalyst/emulsifiers that catalyze reactions in biphasic systems with controlled “phase selectivity”, that is, conversion of the desired reaction on one side of the emulsion. The reaction may affect the solubility of the molecule in one phase, causing migration to the opposite phase. As a result, combined reaction and separation can be ac...
