Columbia Engineering researchers report that they have developed a “cloaking” system that temporarily hides therapeutic bacteria from immune systems, enabling them to more effectively deliver drugs to tumors and kill cancer cells in mice. By manipulating the microbes’ DNA, they programmed gene circuits that control the bacteria surface, building a molecular “cloak” that encapsulates the bacteria.
