In Brief
A team of researchers at MIT introduced a device that allows biological circuits to behave nearly as predictably as their electronic counterparts
  • Synthetic biological circuits can be used to detect markers that indicate the presence of cancer cells, and then trigger the release of molecules targeted to kill those cells
  • Scientists need to work out a safe way for circuits to accurately detect cancerous and noncancerous cells, so they don’t release their killing power in the wrong places
  • The device the team produced to address that problem is called a load driver, and its effect is similar to that of load drivers used in electronic circuits: It provides a kind of buffer between the signal and the output, preventing the effects of the signaling from backing up through the system and causing delays in outputs
