文章

Mesoporous Materials include a range of high surface area porous silicates with applications in gas adsorption, drug delivery, diagnostics and catalysis.

Mesoporous Silica and their Applications

Mesoporous materials are formed by a self-assembly process from combined solutions of sol-gel precursors (e.g., metal alkoxides) and structure-directing amphiphiles, usually block-copolymers or surfactants.

A key challenge for nanomaterial safety assessment is the ability to handle the large number of newly engineered nanomaterials (ENMs), including developing cost-effective methods that can be used for hazard screening.
