What are Nanoparticle Suspensions?
Nanoparticle suspensions, also known as colloidal dispersions, consist of nanoparticles dispersed evenly within a liquid medium. These suspensions leverage the unique properties of nanoparticles, such as their high surface area to volume ratio, to achieve functionalities that are not possible with larger particles. The study and application of these suspensions are integral to the field of
nanotechnology.
Why are Nanoparticle Suspensions Important?
Nanoparticle suspensions are crucial due to their diverse applications across multiple industries. For instance, in
