Van der Waals forces tend to bring nanoparticles close together, causing them to stick. To prevent this, nanoparticles are often coated with molecules that repel each other, such as polymers or surfactants. This coating provides a barrier that prevents the particles from coming into contact and sticking together.

What are cohesiveness?
it means how things are sticking together
Who found nanoparticles?
Michael Faraday is generally considered to be the first person to conduct scientific research on nanoparticles.
What is the effect of silver nanoparticles in plastic?
Silver nanoparticles are antibacterial, and when embedded in plastics for use in the medical field, are non-toxic. This makes silver nanoparticles useful in plastic applications such as surgical catheters.
Do nanoparticles have colors?
Yes, nanoparticles can exhibit a wide range of colors due to their size and shape, which affect how they interact with light. This phenomenon is known as plasmon resonance, where the nanoparticles' electrons resonate with specific wavelengths of light, giving them distinct colors. Designing nanoparticles with specific colors is important for various applications, such as in sensors, imaging, and cosmetics.
What are the main concerns about nanoparticles?
The main concerns about nanoparticles relate to their potential adverse effects on human health and the environment. There is a concern that nanoparticles can penetrate cells and tissues, leading to inflammation or other toxic effects. Additionally, the long-term environmental impact of nanoparticles is not yet fully understood, and there is concern about their bioaccumulation in organisms and potential disruption of ecosystems.
What is aggregation of nanoparticles?
Aggregation of nanoparticles refers to the process by which individual nanoparticles come together to form larger clusters or agglomerates. This can happen due to various factors such as attractive forces between particles, solvent evaporation, or changes in pH or temperature. Aggregation can impact the properties and behavior of nanoparticles, making it important to understand and control in various applications.
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.
