“A new ultrasensitive diagnostic device could allow doctors to detect cancer quickly from a droplet of blood or plasma, report researchers.

The device could lead to timelier interventions and better outcomes for patients.

The “lab-on-a-chip” for liquid biopsy analysis detects exosomes—tiny parcels of biological information tumor cells produce to stimulate tumor growth or metastasize.

“Historically, people thought exosomes were like ‘trash bags’ that cells could use to dump unwanted cellular contents,” says lead author Yong Zeng, an associate professor of chemistry at the University of Kansas.

“But in the past decade, scientists realized…”
