Do you know that many of the products that are currently in the market already have traces of nanotech in them? For example, the sub block lotions that make use of zinc oxide to completely protect against UV rays comes in Nano size since; it has the distinct advantage of being easily removable as opposed to the previous generation of sun block lotions. Furthermore, the smaller size of each particle means that the lotion sets on the skin as a transparent film rather than the ugly white patch seen in older lotions.
A special type of glass that makes use of Nano particles that get activated when exposed to UV rays helps in breaking down organic compounds in the glass and thus remove dust and dirt. Hydrophilic glasses do not hold water at all and help in evenly spreading water over the surface thanks to Nano particles. In the realm of medicine, the biggest innovation to hit the market is that of antimicrobial bandages that make use of silver Nano particles which directly permeate into pathogenic cells blocking their respiration and killing them off.
This is quite handy in battlefields where the chances of infection due to open wounds are higher. LCD displays, wrinkle resistant clothing, better cosmetics and even UV resistant clothes all owe their tribute to the field of nanotechnology. Some advancements in the field that are on the verge of market explosion include Nano level microprocessor chips, bio-Nano batteries to power medical devices implanted in a patient and the use of this technology to miniaturize robots.
