Description Application Adsorbant, catalyst support, nanoscale template Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is an oxide of silicon with the chemical formula SiO2. Large pore mesoporous silica nanoparticles (LP-MSNs) functionalized with poly-L-lysine (PLL) were designed as a new carrier material for gene delivery applications.

The main focus of this thesis has been on synthesis and functionalisation of spherical mesostructured silica particulate materials. A new population of materials, referred to as surfactant templated materials, took form. These materials showed extraordinary properties such as monodisperse pore size distribution, large surface areas and pore volumes. The main focus of this thesis has been on synthesis and functionalisation of spherical mesostructured silica particulate aﬀect the pore size, pore arrangement, and particle diameter has not yet been clarified. In this study, it has been clearly confirmed how trialkyl-benzenes play a multifunctional role in the pore size, particle diameter, and morphology of colloidal mesostructured and mesoporous silica nanoparticles (CMSS and CMPS, respecti- Mesoporous silica materials such as MCM-41, SBA- 15 and HMS with high porosity (pore size of up to 100 Å) have been widely studied as catalyst supports for incur- poration of sulphated metal oxides [5,6], platinum nano- particles and propyl sulfonic acid [8-10]. Since three mesoporous silica carriers (MSNs, MHMS and HMSRs) have similar pore size, etc (see details in table 1), the variable release profiles might be attributed to the influence of their different morphology and helicity. It was observed that the morphology of MSNs was spherical with a 90–100 nm diameter.

This core-shell structured material consists of an Fe3O4 superparamagnetic nanocrystal core and a highly ordered periodic helical mesoporous silica shell. We propose that the formation of
At present, mesostructured silica nanoparticle (MSN) has attracted great fundamental and applied research efforts due to its excellent properties such as large surface area (> 1000 m2 g-1), thermal and mechanical stability, highly uniform pore size distribution, tunable pore size, high adsorption capacity
Novel mesostructured silica microparticles are synthesized, characterized, and investigated as a drug delivery system (DDS) for antimicrobial applications. The materials exhibit a relatively high density (0.56 g per 1 g SiO 2) of benzalkonium chloride (BAC), pore channels of 18 Å in width, and a high surface area (1500 m 2 /g).
