Dendritic Mesoporous Silica Nanoparticles (120-140 nm)
Product Name
Name: Dendritic Mesoporous Silica Nanoparticles (120-140 nm)
Product Overview
Branched mesoporous silica nanoparticles are a novel type of mesoporous silica nanomaterial. They have a unique branched structure that is formed as a complex branched morphology at the nanoscale. Compared to traditional mesoporous silica nanoparticles, their pore structure is more complex and ordered, resembling the branching shape of a tree, providing higher specific surface area and larger pore volume. Mesoporous refers to pores with diameters ranging from 2 to 50 nm that are interconnected within the branched structure, providing a pathway for the adsorption, diffusion, and transport of substances.
Technical Parameter

Note: The specific surface area is the data of a single test, allowing floating between different batches. For reference only, whichever is in kind.
Product Features
1) High specific surface area: The tree-like structure greatly increases its specific surface area, making it excel in adsorption and load capacity. For example, in the field of drug delivery, it can adsorb and load a large number of drug molecules to increase the drug loading capacity.
2) Good biocompatibility: Silica itself has certain biocompatibility, and the tree-like mesoporous silica nanoparticles can exist relatively stably in the body, reducing the toxicity to the body. This makes it have a wide range of application prospects in the field of biomedical, such as bioimaging and tumor therapy.
3) Modifiability: Its surface contains a large number of silicon hydroxyl groups, which can be conveniently chemically modified. For example, targeting molecules or fluorescent molecules can be chemically bonded to the surface, thereby achieving customized functions for the nanoparticles.
Application Fields
1) Drug delivery: A drug molecule can be encapsulated in its mesopore by modifying the surface of the nanoparticle so that it can target a specific cell or tissue. For example, in cancer therapy, anti-cancer drugs are loaded onto dendritic mesoporous silica nanoparticles, and then antibodies that recognize tumor cells are attached to the surface of the particles, so that the nanoparticles can precisely deliver the drug to the tumor site, reducing side effects on normal tissue.
2) Bioimaging: It can be used as a carrier for contrast agents. Due to its modifiability, fluorophores, such as fluorescein, quantum dots, etc., can be connected for cell imaging and in vivo imaging. In cell imaging, the distribution and transport process of nanoparticles within cells can be observed, providing tools for the study of physiological and pathological processes within cells.
3) Adsorption and separation: With its high specific surface area and rich pore structure, it also has important applications in the field of adsorption and separation. For example, it is used for adsorption of heavy metal ions and organic pollutants in the environment, or for separation and purification of biological macromolecules, such as proteins and nucleic acids.
