Researchers constructed integrated gene logic-chips called 'gene nanochips.' These self-contained nanochips can switch genes on or off according to the environment, where photo-reprogramming of the logic operation by UV irradiation is possible. Moreover, the researchers completed proof-of-concept experiments using artificial cells that produced the diagnostics and reactants (the desired RNA and protein) in a confined nanochip, suggesting the potential of autonomous nanochips in future medical prevention and care.
