Microrobots Deliver Chemotherapy Directly to Lung Tumors in Mice

UC San Diego engineers develop algae-based microrobots that improve survival rates by targeting metastatic lung cancer.

Microrobots combine green algae with drug-filled nanoparticles to navigate lung tissue and deliver chemotherapy.
The nanoparticles are coated with red blood cell membranes to evade the immune system and prolong drug retention.
In treated mice, the microrobots extended median survival time from 27 to 37 days compared to control groups.
The technology builds on previous successes in treating pneumonia, showcasing its versatility for lung diseases.
Researchers aim to advance to larger animal trials and eventually human clinical trials.
