Nowadays nanotechnology is in most of the aspects on our daily basis. It can be found in our smartphones, washing machines, cars, and health issues, in brief, it is everywhere. What relationship has this to colloidal particles? In fact, there are many reason to think that. Colloids are tiny particles of diameters between 10-6 and 10-9 meters suspended in a fluid, such as a liquid or gas. Colloidal suspensions are found in nature in common systems like milk, blood, detergents, fog, whipped cream and many others. Some examples of applications are cargo transportation, drug delivery, biological pump systems, etc. These applications could not be possible without an integrated use of technological design and nanoparticles.
