Overview of Nanoparticles
Nano powder is also called nanoparticles, which generally refers to ultra-fine particles with a size between 1-100nm. Some people call it ultrafine particles. Its size is larger than atom clusters and smaller than ordinary particles. Calculated according to its size, assuming that each atom is 1 angstrom in size, it contains between 1000 and 1 billion atoms. Nanoparticles are smaller than normal biological cells and is about the size of a virus. The morphology of nanoparticles is spherical, plate, rod, horn, sponge, etc. The constituents of nanoparticles can be metals, oxides, or other various compounds.

Applications of Nanoparticles
Nanoparticles are being used in many applications to improve the environment. For instance, photocatalytic copper tungsten oxide nanoparticles are being tested to break down oil into biodegradable compounds. The nanoparticles are placed in a grid to provide high surface area for the reaction. Nanotechnology is being used by many manufacturers to develop products with better capabilities or to lower production costs.

5 FAQs of Nanoparticles Materials
What are the main applications of nanoparticles?
Nanoparticles find applications in various fields including medicine (drug delivery, imaging), electronics (nanoelectronics, sensors), energy (batteries, solar cells), and environmental remediation (pollutant degradation). They are also used in cosmetics and as catalysts.
How do you measure the size and shape of nanoparticles?
Techniques such as Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), and Dynamic Light Scattering (DLS) are commonly used to measure the size and shape of nanoparticles. These methods provide detailed information about particle morphology and distribution.
Are nanoparticles safe to use in consumer products?
The safety of nanoparticles depends on their type, concentration, and how they are used. Regulatory bodies often require thorough testing to ensure their safety in consumer products. It's important to follow guidelines and conduct risk assessments before incorporating nanoparticles into products.
Can nanoparticles be functionalized?
Yes, nanoparticles can be functionalized to improve their properties or to achieve specific functionalities. Functionalization typically involves attaching molecules or other nanoparticles to the surface of the nanoparticles to enhance solubility, stability, or reactivity.
What factors affect the stability of nanoparticles?
Several factors can influence the stability of nanoparticles, including their size, shape, surface charge, and environment (pH, temperature, presence of salts, etc.). Proper stabilization techniques, such as coating with surfactants or polymers, can help maintain nanoparticle stability during storage and use.
