Scientists from the Institute of Automation and Control Processes of the Far Eastern Branch of the Russian Academy of Sciences, together with their colleagues from Spain and Japan, synthesized a silicon and gold-based nanomaterial to combat counterfeit products. This was reported to socialbites.ca by the Russian Science Foundation, which supported the project with a grant.
The nanomaterial absorbs light with 96% efficiency and then converts it into heat – thanks to this feature it can be used as a nanothermometer. The authors note that it is possible to create films with a unique pattern from a nanoparticle placer. These films can be used to create protective optical labels to combat counterfeit products.
“The coding ability of such optical tags is 10 to the 3000, so that’s the number of attempts an attacker would need to randomly repeat any tag. This makes it physically uncopyable,” explains Candidate of Physical and Mathematical Sciences, Senior Researcher, IAPU. FEB RAS, project manager Stanislav Gurbatov.
According to scientists, nanoparticle synthesis technology is simple. Its high efficiency, reaching several grams per hour, makes it commercially attractive for nanosensors, solar energy conversion and anti-counterfeit marking.
“In the future, we plan to study in more detail the optical properties of the obtained nanoparticles, depending on the initial concentrations of the components and the type of solvent,” says Vladislav Puzikov, a graduate student and engineer at the Control and Engineering Institute.
