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.

Game changer..get one!
My floors had varying levels of dirt (think heavy traffic area vs lighter traffic areas) and the detection system masterfully targeted areas until they were super clean. This is a good value, time saving and elevated my quality of life.

Works great, might have to use distilled water if you have hard water
So far it's great! It uses a LOT of water on the first clean (and maybe also because of using the 'Freo' ai mode) you can use tap water, but in areas with hard water, you might need to go through a lot of distilled water. I think on future cleaning jobs it's supposed to use less water though. And you can adjust the cleaning level to a lower setting so that it doesn't use as much. The app takes a little while to get used to, because there are many options and menus. But still very nice to have and use. The vacuum has a dust bin with a very basic filter (needs replaced every 30 days if used), but if you want more of 'Hepa' clean air, you would have to use another type of vacuum before mopping. It also doesn't get close to the edges of some areas for some reason, even thought it could fit. Still, for what it is, it's a great product that will cut down on a lot of mopping time.

Worth every penny. Highly recommend!
To say I love my Narwal robotic mop and vacuum is an understatement—total game changer. I can’t imagine going back to any other robotic vacuum. I have two dogs, including a Jack Russell who sheds like Pig-Pen from Peanuts—basically a walking cloud of hair—and this thing handles it effortlessly. The vacuum + mopping combo is amazing, and it’s so easy to use and maintain. It truly does all the dirty work for me. I did have a small hiccup about two months in, but Narwal support helped me reset it quickly and it’s been perfect ever since (I definitely panicked for a minute 😅). Worth every penny. Highly recommend!

Unreliable. Doesn't work.
Has been every unreliable. Misses lots of spots with horrible mapping. Doesn't go some places for some reason. We moved the furniture, tried remapping but nothing works. Randomly goes in circles in the same spot at times. Updated firmware, spoke to support etc. When using vacuum and Mop option, it skips carpets and doesn't go back to do them afterwards. The whole programming is unreliable. Don't BUY. Can't return it past the warranty/return period.

LOVE ❤️
I’ve only had this for a few days but I am in LOVE with it and maybe a little obsessed. Even my husband commented on how clean our floors were after the first use. The mapping feature works very well; better than my previous robo vac. I love that it takes the everyday maintenance out of the equation by cleaning/drying the mop heads itself. I wish the instruction manual had more info in it, as well as what some of the features on the app entail, but I’m sure google can provide that info. I’m very pleased with this product.
