Product Name
Monodisperse Mesoporous Silica Nanosphere Stellate
Product Overview
Silica nanoparticles can be broadly classified into three types based on their morphological characteristics: solid silica, mesoporous silica and hollow-structured silica. Among them, the pore structure of mesoporous silica is generally formed by the template method. The preparation process of mesoporous silica can be divided into two stages: firstly, the template interacts with the inorganic precursor, and under certain conditions, the organic and inorganic substances are synthesized with nano-sized lattice constants of the liquid crystalline state of the structural phases; and then the template can be removed by using high-temperature heat treatment or other physicochemical methods, and the space left behind the template constitutes a mesoporous pore channel. Compared with conventional mesoporous silica, monodisperse mesoporous silica nanorods have a pore structure with more complex and abundant connectivity between the pores, and the large pore size can also accommodate larger-sized molecules or particles, which has the advantages of high loading capacity and high utilisation rate.
Technical Parameter
Form：white powder
Average Size:0 nm
Pore volume：~1.4 m2/g
Pore Size (conical pores of the stellate MSNs):.9 nm
Product Features
Larger pore size: able to accommodate guest molecules with larger sizes, such as macromolecular drugs, proteins, nanoparticles, etc., which provides a broader space for its application in biomedicine, catalysis and other fields.
High porosity: provides a large specific surface area and pore volume, which is conducive to the adsorption and loading of a large number of substances.
Loading and controlled release capability: It can achieve efficient loading of drugs and other substances, and can achieve precise controlled release of loaded substances by means of surface modification and other means to improve the therapeutic effect.
Application Fields
Drug delivery: loading of anti-cancer drugs such as Adriamycin into dendritic mesoporous silica. Due to its large pore size and good controlled release properties, the drug can be released slowly at the tumour site, improving the therapeutic effect while reducing the side effects on normal tissues.
Gene Carrier: As a gene carrier, it protects genes from degradation by nucleases and delivers genes into cells.
Catalysis: In multiphase catalysis, dendritic mesoporous silica can be used as a carrier to load metal nanoparticles or enzymes. For example, loaded platinum nanoparticles are used to catalyse hydrogenation reactions to improve reaction efficiency and selectivity.
