Amino Modified Dendritic Large Pore Mesoporous Silica

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, dendritic mesoporous silica has a dendritic 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

 

 

Average size:~100 nm

Specific surface area:05.71m2/g

Average pore size:~13nm

Note: The BET data is a single measurement of a 100nm particle size product, allowing floating between different batches.    

Product Features

 

Unique pore structure: with a dendritic structure, this structure increases the internal pore connectivity and material transport channels. 

Larger pore size: able to accommodate guest molecules of larger size, 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. 

Good diffusion performance: dendritic pore channels and large pore size, substances can diffuse and transport rapidly in them. 

Loading and controlled release ability: 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. 

Sensors: Due to its adsorption ability on target molecules and changes in optical properties, it can be used to construct chemical sensors, such as detecting heavy metal ions or organic pollutants in the environment.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.
