Product Overview

Silica-coated silver nanoparticles (Ag@SiO2) is a nanocomposite material with special structure and properties. Ag@SiO2 nanoparticles have a typical core-shell structure, that is, silver nanoparticles serve as the core and the silica shell The layers are tightly packed around the core. This structure not only improves the stability of silver nanoparticles, but also gives them new properties. The silica shell provides good chemical stability to the silver nanoparticles, preventing them from reacting with chemicals in the environment. Maintaining its original physical and chemical properties, the thickness and morphology of the silicon layer can be precisely controlled by adjusting the parameters during the preparation process. Ag@SiO2 nanoparticles have good stability, biocompatibility, controllability, optical properties, antibacterial properties and surface functionalization, and have shown broad potential in biomedicine, optical sensing, drug delivery and other fields. Application prospects.

Product Features

Chemical stability: The silica shell provides good chemical stability to the silver nanoparticles, preventing them from reacting with chemicals in the environment, thereby maintaining their original physical and chemical properties.

Optical properties: The presence of silica shell can affect the optical properties of silver nanoparticles, such as plasmon resonance wavelength. By adjusting the thickness and morphology of the shell, precise control of the optical properties of silver nanoparticles can be achieved.

Antibacterial properties: Silver nanoparticles themselves have excellent antibacterial properties, and coating with silica shell can further improve their antibacterial effects. At the same time, mesoporous silica-coated silver nanoparticles (Ag@mSiO2) also have a larger specific surface area and better antibacterial persistence.

Biocompatibility: Ag@SiO2 nanoparticles have good biocompatibility, which means they can be used safely in living organisms without causing severe immune reactions or toxic reactions. This feature makes it have potential application value in the biomedical field, such as drug delivery, bioimaging, etc.

Application Fields

Antibacterial materials: Ag@SiO2 nanoparticles can be used to prepare various antibacterial materials, such as antibacterial coatings, antibacterial textiles, antibacterial plastics, etc. These materials have broad application prospects in medical, food packaging, household products and other fields.

Biosensing: Using the optical properties of Ag@SiO2 nanoparticles, highly sensitive biosensors can be constructed for detecting biomolecules, ions and other targets.

Catalysis field: Silver nanoparticles show excellent performance as catalysts in multiple chemical reactions, and coating with silica shell can further improve their catalytic activity and stability.

Great to keep your dog entertained
Color: Blue
Great toy my 13 month old cane corso absolutely loved it and it kept her entertained forever except she has an extremely strong bite so she was figuring out a way to split it apart so I had to take it away -it’s extremely strong, but not strong enough for the bite of a cane corso but any other dog would love it. I just wish my dog didn’t have such a strong bite and would be able to keep enjoying it since it is a little expensive the only problem with it is that I thought the remote shuts it off, but then her bites were making it come back on, so I don’t know if it was my dog or the toy just doesn’t stay off until you turn it on.

Stopped working within 3 days
Color: Blue
Worked for 3 plays. My 11 week old puppy loved this item. Unfortunately, it only lasted 3 tries before the motor stopped working. $30 for a total of 30 minutes over 3 days is robbery! I'd look at another vendor for the same type of item. We charged it after each attempt but now the motor won't turn on.

Item was returned
Color: Blue
Used it one day and partially the following day. Put on charger. Never worked again. My dog played with it but returned it as defective.

Not for super chewers
Color: Blue
This ball seems to be of good quality; has held a charge well and is easy to use. Sadly, the cover lasted less than 15 minutes with our dog.... not for aggressive chewers for sure. Pretty funny to watch the hound dog jowls shake though.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.
