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

Status:White powder

Particle size:120-140 nm

Specific surface area:~639 m2/g

Average pore size:20-22 nm

Pore volume:~3 cm2/g

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.

Fits 2005 325xi
Size: 2002-2005 E46
Snapped perfectly into place. Zero play with the fit and hood hinge still just as accessible as oe grille. No trimming required. If you’re sick of snapping your grille back in every time you lift the hood, buy it! I also have the colored grill inserts and they snap on perfectly with no play. https://a.co/d/3F83eFx

Fit is perfect and these have a very nice glossy finish
Size: 2002-2005 E46
Fit is perfect and these have a very nice glossy finish, which looks much better than the matte finish. As others have said, the driver's side grill lacks a cut out where the hood latch pull handle swings out when you need to lift the hood (compare the driver's side grill with the existing grill to see location and size of the cut out). I was able to cut an opening within 10 minutes and I haven't had any problems opening the hood since the installation.

Nice Finish, Decent Fit
Size: 2002-2005 E46
The fitment isn't perfect like the OEM grilles, but overall I was satisfied. These are just slightly smaller than the originals so there is a little play once installed. No need to modify the LH side grille for clearance to the hood latch though as other reviews mention. It looks like the design has been revised to address that problem. I was impressed with the paint finish and there weren't any noticeable blemishes like dust or dirt in the paint. These are probably the best and cheapest gloss black kidney grilles for E46 that are currently available. OEM grilles w/ gloss black are basically discontinued so we're all stuck with aftermarket if you want the gloss black shadowline look.

loose fitment
Size: 2002-2005 E46
I guess it's a hit or miss with this. You either get perfect fitment or poor fitment like I did, after the install it's very loose.

Awful fitment, poor quality
Size: 2002-2005 E46
Although not oem quality was expected, but I never thought to throw them away either. Grills look very nice, outside quality is good. Unfortunately the grills do not fit to its place and slip just after you close the hood. After several tries to make them stay in place I have broken 2 clamps. Finally I have removed these grills and went on with OEM ones. Also, pay attention that you must drill a space for hood lock on the inner side (driver side grill does not have the factory space for hood lock handle).
