Product Overview

As a common inorganic nanoparticle, silica nanoparticles have a series of advantages such as controllable morphology, orderly and adjustable pore structure, large specific surface area, easy modification of surface functional groups, and good biocompatibility, which make them widely used in biomedicine, catalysis, environmental protection, optics and other fields.

The main preparation method of silica nanoparticles is sol-gel method, and the silicon source is formed by hydrolysis polycondensation under catalysis. The method was first proposed by Stober in 1968. According to the morphology characteristics of silica nanoparticles, they can be roughly divided into three types: solid silica, mesoporous silica and hollow mesoporous silica. As a common mesoporous material, hollow mesoporous silica nanoparticles (HMSN) have good stability, low toxicity and high biocompatibility, due to their highly permeable mesoporous shell and internal cavity easy to load guest substances (such as organic small molecules, inorganic particles with optical properties or magnetic properties, protein macromolecules), in catalysis, drug controlled release, controlled synthesis. Energy storage and environmental protection have a wide range of application prospects.

The surface of silica nanoparticles is rich in silicon hydroxyl group, which is conducive to the chemical modification of the surface. By modifying different functional groups, silica nanoparticles can be given more functions. At present, the commonly used surface modification types are surface amination, carboxylation, sulfhydrylation, organic chain functionalization and so on. The surface modification of silica nanoparticles is mainly through the introduction of different types of silane coupling agents, such as 3-aminopropyl triethoxysilane (APTES), which can be used for amination modification, succinic anhydride can be used for carboxylation modification, and 3-mercaptopropyl trimethoxysilane can be used for sulfhydryl modification.

Product Features

 

1. Unique hollow structure: there is a hollow area inside, which can be used to load and encapsulate various substances.

2. Protective effect: It can protect the encapsulated substance from the influence of the external environment, such as light, heat, chemical substances, etc.

3. Good biocompatibility: When applied in the biomedical field, it usually has low toxicity and good biocompatibility.

4. Good chemical stability and thermal stability: can maintain structural stability in a wide temperature and chemical environment.

5. Surface modifiability: Its surface is easy to be chemically modified to meet different application needs.


Application Fields

1. Biomedical materials: The hollow mesoporous silica material not only has a loose shell with adjustable pore size, but also has an internal cavity with controllable size, which can be used as a carrier of the guest material, separate the guest material from the surrounding environment, and transport it to the appropriate location after release. Therefore, it can be used as a carrier for drug slow release/controlled release and enzyme immobilization.

2. Catalytic carrier: hollow mesoporous SiO2 material has regular pores, large specific surface area and good stability. Using hollow mesoporous SiO2 material as the carrier of supported catalysts (such as nano Au, Pt, Ag, etc.), its large specific surface area can improve the dispersion of the catalyst, while the catalyst nanoparticles highly dispersed in its pores are not easy to aggregate and grow, thus improving the stability of the nanoparticles in the reaction and improving the catalytic efficiency.

3. Adsorption material: Hollow mesoporous SiO2 material is stable and reusable due to its large pore volume, adjustable pore size and high specific surface area, and is an excellent carrier for adsorption materials. Its surface contains a large number of easily modified silicon hydroxyl groups, which can be prepared with selective adsorption and separation materials by introducing functional groups such as -NH2, -S- and -SH.

Color: Multi Squeaker Balls, Size: Medium, Style: 4-Pack
This dog squeak ball has been a big hit in my home and keeps my dog entertained for long periods of time. The squeaker really grabs their attention and encourages play, tapping into their natural instincts to chase and fetch. My dog especially loves how it bounces and squeaks, making it perfect for both indoor and outdoor play. It’s lightweight and easy for them to carry around, even for quick games of fetch in the yard. In terms of durability, it has held up pretty well so far. The squeaker may not last forever with heavy use, but the ball itself still stays in good shape. Overall, it’s a fun, engaging toy that keeps my dog active and happy.

budget friendly for dogs who lose balls in the creek
Color: Multi Squeaker Balls, Size: Medium, Style: 4-Pack
Not great quality, but works for our needs. I have a ball crazy lab. She loves for me to throw a ball using the Chuck-it Ball Launcher. We do this in our wide back yard that butts up to a creek. At some point during her run and fetch, she will take a quick detour right into the creek. She nearly always still has the ball, but once in awhile it is lost. Not wanting to chance it on more pricy (and more durable) balls, I get these or something like these. They dont cost much, yet they do the job. I' not upset if one gets sacrificed to the creek waters and mud. Since the balls end up getting wet often, they will kinda fall apart over time (chasing, kicking, throwing, retrieving, dog saliva etc). But she doesn't chew on them. Glad she doesnt as tennis balls arent good on teeth, but even if it was ok, the balls probably would be breached easily. SO get these if you are like me and want a ball that does the job but arent a total financial loss if get lost or destroyed. For indoor play we and by we I mean our 3 dogs demand that we use the rubbery max glow chuck-it ball. And will ignore this style ball. Yes, I am well trained. lol

These balls SUCK! External squeakers, minimal bounce and blue that is too dark.
Color: Multi Squeaker Balls, Size: X-Small, Style: 8-Pack
We have 2 little dogs in our home - a 1.5 year old Pomsky, and a 9 year old Pekingese. My Peke has shown no interest in tennis balls for years, until today! Imagine my excitement! Until she promptly destroyed the first squeaker on one of the blue balls. When I removed it, she began peeling the logos off the ball, and then started tearing the fuzz off! My dog has never destroyed any toy in her life, so this was shocking! Then the Pomsky decided that she wanted to play fetch with the new balls - she has Golden Retriever energy - and decided to destroy a squeaker in the midst of playing! She also wasn't nearly as interested in these tennis balls as her other tennis balls that she inherited from my Peke. 1. STUPID design, with the squeakers sticking out of the balls (the don't sit flush), so they are asking to get chewed or pulled out by any dog, even elderly 10 lb dogs! And a 9 lb young adult. 2. They are difficult to squeak compared to their Kong tennis balls, hence why the Pomsky wasn't interested for long. 3. They don't bounce as much as the Kong tennis balls, either, which made them less than exciting for the athletic and agile Pomsky. Meh. We wanted to get the smallest tennis balls we could get (1.5 inch) because neither dog will play with the 2 inch or bigger ones, but we also wanted to get colors they could easily see! The Pomsky clearly prefers the yellow balls to any other color (red, orange, green, darker blue, watermelon design), so we wanted to get like a bright blue or turquoise couple of balls to appeal to them! Well, my senior Peke liked the blue ones the most, but also liked the red and orange. Pomsky didn't like the blue ones. I think they're too dark of a blue to be easily seen in our home afternoons and evenings in the winter. We love Outward Hound toys in our house, but these were an expensive FLOP. They are the right size, but WHY did they put the squeakers so visible and appealing to dogs? I've never seen the squeaker in the Kong tennis balls. My advice is that Kong seems to make the best tennis balls for toy breeds, in the 1.5" size. Outward Hound dropped the ball here... no pun intended. The blue is darker than the photos depict (may be better in natural sunlight outdoors), the squeakers are external, and they barely bounce at all. Our next step will be to get the pressurized bright blue tennis balls from another brand, in hopes that the bounce and visibility will outweigh the lack of squeakiness. If those don't work, I guess we'll stick to the classic neon yellow Kong tennis balls! At my local Target, they only have multicolor packs of them, and the dark blue, red and green get completely ignored. *Dogs can only see shades of blues, yellows and black, grey and white. While some dogs may not seem to care about color, our Pomsky clearly does. :(

My Dog Loves Them
Color: Multi Squeaker Balls, Size: Small, Style: 8-Pack
These cute little squeaky balls are the perfect size for my Shih Tzu. She loves to chew on them and make them squeak all the time, so they are durable. I would purchase them again.

Not super durable but good squeak while they work
Color: Multi Squeaker Balls, Size: Large, Style: 4-Pack
My dog loves these but they break very quickly. I've got an older set that was incredibly durable, but these all stopped squeaking/got holes after the first or second play session
