Bacteria-based Biohybrid Microrobots on a Mission to one day Battle Cancer

Bacterial biohybrids carrying nanoliposomes (200 nm) and magnetic nanoparticles (100 nm). Nanoliposomes are loaded with chemotherapeutic DOX and photothermal agent ICG, and both cargoes are conjugated to E. coli bacteria (2 to 3 µm in length) via biotin-streptavidin interactions. Akolpoglu et al., Sci. Adv. 8, eabo6163 (2022).

A team of scientists in the Physical Intelligence Department at the Max Planck Institute for Intelligent Systems have combined robotics with biology by equipping Ecoli bacteria with artificial components to construct biohybrid microrobots. First, the team attached several nanoliposomes to each bacterium. On their outer circle, these spherical-shaped carriers enclose a material (ICG, green particles) that melts when illuminated by near infrared light...
