Product Overview

Mesoporous materials (pore size 2-50nm) have a pore size between microporous materials (pore size<2 nm) and macroporous materials (pore size>50 nm), and possess many excellent characteristics, such as highly ordered pore structure, single pore size distribution, and high stability, making them a hot research topic in recent years. As a common inorganic nanoparticle, silica nanoparticles have a series of advantages such as controllable morphology, ordered and adjustable pore structure, large specific surface area, easy modification of surface functional groups, and good biocompatibility, which make them widely used in biomedical, catalytic, environmental protection, optical and other fields. According to the morphological characteristics of silica nanoparticles, they can be roughly divided into three types: solid silica, mesoporous silica, and hollow structured silica. Among them, the pore structure of mesoporous silica is generally formed by template method, which includes soft templates and hard templates. The surface of silica nanoparticles has abundant silicon hydroxyl groups, which facilitate their surface chemical modification. By modifying different functional groups, silica nanoparticles can be endowed with more functions.

Application


1. Drug delivery: Loading anti-cancer drugs into the pores of mesoporous silica to achieve slow drug release. By surface modification, drugs can target specific tumor cells, improving therapeutic efficacy while reducing damage to normal cells.
2. Biological imaging: Load fluorescent molecules (FITC, Cy5.5) or magnetic nanoparticles for imaging cells and in vivo, achieving real-time monitoring of intracellular biological processes.
3. Gene therapy: As a gene carrier, it protects the stability and transmission efficiency of genes in the body.
4. Diagnostic reagents: used to detect biomarkers, such as molecules loaded with specific recognition of disease-related markers, to achieve early diagnosis of diseases.
5. Organizational engineering: As a scaffold material, it promotes cell growth and tissue regeneration.
