TR 100 Biotech and Medicine

Yaakov Benenson wants to shrink your doctor. Or more accurately, he wants to replace physicians with molecular machines that diagnose and treat diseases with phenomenal precision, each what he calls a “doctor in a cell.”

In just five years, Benenson has taken the concept from drawing board to test-tube prototype. Working at the Weizmann Institute of Science in Rehovot, Israel, he has built molecular devices - essentially DNA strands and enzymes - able to analyze genetic changes associated with lung and prostate cancers and to release a drug in response.
