This new research ties into previous work by the University of Maryland where researchers found ways to "record" biological information by sensing the biological environment, and based on the prevailing conditions, "write" electrons to devices. Through these electrochemical devices, researchers were able to identify pathogens, and even monitor signs of stress in the blood levels of people with schizophrenia. In light of this previous research, the new study could potentially allow bacteria to be electronically programmed to deliver therapeutics to a specific site to help resolve such health problems.
