Mesoporous Solid-core Silica Nanoparticles:00-120 nm)


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, optical and other fields. The main preparation method of silica nanoparticles is the sol gel method. Under the catalysis, the silicon source is formed by hydrolysis and condensation. This method was first proposed by Stober in 1968. 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. Soft templates are generally amphiphilic surfactants, while hard templates are generally high molecular weight polymers, with soft templates being more commonly used. The preparation process of mesoporous silicon can be divided into two stages: firstly, the template interacts with the inorganic precursor to synthesize liquid crystal structural phases with nanoscale lattice constants of organic and inorganic materials under certain conditions; Then, high-temperature heat treatment or other physical and chemical methods are used to remove the template, and the space left by the template forms mesoporous channels. 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. The commonly used types of surface modifications currently include surface amination, thiolation, and organic chain functionalization. The surface modification of silica nanoparticles is mainly achieved by introducing different types of silane coupling agents, such as 3-aminopropyltriethoxysilane (APTES), which can be used for amination modification, and 3-mercaptopropyltrimethoxysilane, which can be used for thiol modification.

Product Features

1) Multiple active sites: Due to its large specific surface area and abundant surface active sites, amination solid mesoporous silica nanoparticles can be used as catalyst carriers to improve the activity and selectivity of catalytic reactions.

2) Large specific surface area: due to the existence of mesoporous structure, it has a large specific surface area, which is conducive to adsorption and loading of drugs or other molecules.

3) Good hydrophilicity and biocompatibility: Amination improves the hydrophilicity and biocompatibility of nanoparticles, which contributes to their application in vivo.


Application Fields

1) Biomedicine: In the field of drug delivery, aminoated mesoporous silica nanoparticles can be used as drug carriers to achieve targeted drug delivery and controlled release;

2) Catalytic carrier: as a catalyst carrier, its high specific surface area and ordered pore structure are conducive to catalyst dispersion and mass transfer of reactants;

3) Adsorption separation: After surface amination, the surface of the nanoparticles has a positive charge, which helps to adsorb negatively charged substances, such as some pollutants and biomolecules;

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.

Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.

Great Quality for the Price
Size: 100 Count (Pack of 1)
Love these paper plates. They’re sturdy, microwave-safe, and hold up well without getting soggy or folding easily. Great for everyday use and cleanup is super convenient. Good value for the price and reliable for meals and snacks.
