A team that hails from the Worcester Polytechnic Institute in the US discovered that selected nanoparticles do feature special characteristics that are able to mark different items, and this particular technique could then deliver a connection between the objects and their manufacturer, seller or buyer.
Also known as invisible barcodes, Dr. Ming Su, who is behind this research, shared, “Nanoparticles are so small, they can be put into any objects.” Such covert barcodes would definitely come in handy when fighting crime and help to reduce the incidences of counterfeiting. Dr. Su continued, “The nanoparticle does not participate in any chemical reaction, and it will not effect the function of the existing object. The only thing it will do is to provide a thermal signature.”
