Nanoparticles are used in sunscreens. They offer protection and can be rubbed in so they block harmful ultraviolet light from the sun without white marks on the skin . This is because it contains titanium dioxide nanoparticles which are so small that they do not reflect visible light, so they cannot be seen.

Sports equipment:

Nanoparticles are added to materials to make them stronger whilst often being lighter. They have been used in tennis rackets, Golf clubs and shoes

Clothing:

Silver nanoparticles have been added to socks. This stops them from absorbing the smell of sweaty feet as the nanoparticles have antibacterial properties

how does electrostatic forces prevents the nanoparticles to aggregate?

Electrostatic forces repel the nanoparticles from each other due to their like charges, preventing them from aggregating. This repulsion helps maintain the stability and dispersion of the nanoparticles in a solution by keeping them evenly distributed and separate.


Why are gold nanoparticles red?

Gold nanoparticles appear red because of a phenomenon called "localized surface plasmon resonance." This occurs when the electrons on the surface of the gold nanoparticles vibrate in response to light, absorbing and scattering certain wavelengths of light, which gives them their red color.


How do you identify redshift occur in nano particle determination?

Redshift in nanoparticles is identified by observing a shift in the wavelength of light emitted or absorbed by the nanoparticles compared to the original wavelength. This shift indicates a change in the energy levels and size of the nanoparticles. Techniques such as UV-Vis spectroscopy or fluorescence spectroscopy can be used to detect redshift in nanoparticles.


What is difference between macro and nanoparticles?

Macroscale structures are typically larger, like the size of human hair or larger, while nanoparticles are on the nanometer scale, typically between 1-100 nm in size. Nanoparticles have unique properties due to their small size, such as high surface area to volume ratio and quantum effects, which can make them useful in a variety of applications.


Can physics be called science?

Yes, physics is considered a science because it uses the scientific method to study and interpret the natural world. It relies on observation, experimentation, and mathematical models to understand the fundamental principles governing the behavior of matter and energy.

Are nanoparticles the same as ordanary particles?

No, nanoparticles are particles that are extremely small, typically between 1-100 nanometers in size, whereas ordinary particles are larger. Nanoparticles exhibit unique physical and chemical properties due to their small size, making them useful in various applications such as medicine, electronics, and environmental science.


What nanoparticles are in a swimsuit?

Some swimsuits are made with nanoparticles such as titanium dioxide or silver nanoparticles. Titanium dioxide nanoparticles can provide UV protection, while silver nanoparticles may help inhibit bacterial growth and odor.


What is mean by cluster nano particles and the nano particles?

Cluster nanoparticles refer to aggregates of nanoparticles that are grouped together, often exhibiting distinct physical and chemical properties compared to individual nanoparticles. Nanoparticles themselves are tiny particles with dimensions in the nanometer scale (1 to 100 nanometers) and can have unique characteristics due to their small size, such as increased reactivity and surface area. These properties make both individual nanoparticles and their clusters useful in various fields, including medicine, electronics, and material science. The behavior and applications of cluster nanoparticles can differ significantly from those of larger particles or bulk materials.


What is the difference between nanoparticles and nanotechnology?

Nanoparticles are particles that are at the nanoscale (1-100 nanometers in size), while nanotechnology refers to the manipulation and application of materials at the nanoscale to create new functionalities and products. Nanoparticles are one of the building blocks of nanotechnology and play a key role in enabling various applications in fields such as medicine, electronics, and materials science.
