They use light to mix liquids in tiny vessels.
Researchers with ITMO University in cooperation with colleagues from the Czechian Academy of Sciences have suggested a method to mix liquids using light, a spokesperson for the University told Saint-Petersburg TV Channel.
Liquids in microreactors, or, labs-on-a-chip, cannot be mixed with even a thinnest needle or a hair, which makes it impossible to mix reagents and thus accelerate diffusion.
To solve the problem, St. Petersburg researchers invented a nanoantenna, a device invisible to the human eye that can control a light wave creating a ‘light mixer’.
The system has been developed and calculated in theory, tests and experiments are ahead.
