Researchers have developed the technology of controlled cultivation of nanocrystals, which allows millions of types of atomic barcodes suitable even for marking individual elements inside living cells.
Traditional barcodes are used for labeling and identifying various items, but a decrease in them in millions of times opens up new opportunities for fundamental research. Scientists from Sydney University found a way to achieve this.
The team has developed a method for the production of homogeneous crystalline nanterine, which allows you to control the direction of their growth, thickness, composition and distance between functional elements, adjusting individual atomic layers. Since the inorganic structures obtained are chemically and optically stable, they can be used as nanoscopic bar codes or data carriers.
If such crystals are upgraded and supplemented with functional molecules, they can be turned into probes to study building elements of life, as well as apply for delivery of drugs or other bio-engineering purposes.
Nanoscower codes can also be used to protect against fakes of expensive goods by adding them to marking inks.
Recently, Korean scientists offered another innovative method of protection against fakes with
