Guardant’s founders Eltoukhy and Talasaz want to remake cancer screening with their “liquid biopsy” technology, which can sniff out DNA fragments in the blood that indicate cancer-related biological markers. The method has drawn plenty of interest — and capital — despite initial skepticism. Guardant raised $360 million in May, and aims to sequence more than 1 million cancer patients’ DNA within five years.
