Google's agent designs DNA aptamers; no control arm was run

Google Research has an AI agent drive lab robots to design DNA aptamers, and confirmed hit rates reach 33.5% and 42.1% on two targets after three rounds

Concept illustration: on a long counter, a laptop at left whose screen shows a speech bubble with grey lines is joined by a black cable to an orange-red robotic arm in the centre, which lowers six red-tipped pipette tips into a white plate covered in small wells. Above hangs a sign lettered GOOGLE RESEARCH beside a large red, yellow, green and blue letter G, and at right a person with long dark hair, wearing a white lab coat and a badge on a lanyard, stands behind the counter, which has grey cabinets below.

Why it matters: Once AI speeds up design proposals, the wet-lab bottleneck shifts to experimental readouts. We make no new call today.

Google Research had an AI agent drive lab robots to design DNA aptamers in loops of 7 to 10 days; after three rounds the confirmed hit rate reached 33.5% for myoglobin and 42.1% for α-thrombin, compared only with earlier rounds of the same experiment, and Google writes that experimental readouts are more of a bottleneck than ever (Google Research, 2026-10-16). These are research prototypes, and the results are Google's own.
