Nanotechnology is a branch of science primarily concerned with matter at the scale of one billionth of a meter. Decrease in particle size is associated with increase in chemical, biological, physical and ratio of surface area to related bulk density properties and hence nanomaterials are very useful in drug delivery or as the antiviral agent/antimicrobial agent. No much talk on this, Google nanotechnology in drug delivery and as antimicrobial agent etc.. etc... The attachment of Clement and others may be very helpful as well
Nanotechnology has been using in targeted drug delivery owing to it remarkable properties such as antimicrobial. So, it can be assisted to cope up with this thretful deases.
