Bacterial Minicell-Based Biohybrid Sub-micron Swimmers for Targeted Cargo Delivery.

ABSTRACT: Bacterial biohybrid microrobots possess significant potential for targeted cargo delivery and minimally invasive therapy. However, many challenges, such as biocompatibility, stability, and effective cargo loading, remain. Bacterial membrane vesicles, also referred to as minicells, offer a promising alternative for creating sub-micron scale biohybrid swimmers (minicell biohybrids) due to their active metabolism, non-dividing nature, robust structure, and high cargo-carrying capacity. Here, a biohybrid system is reported that utilizes motile minicells, ≈400 nm in diameter, generated by aberrant cell division of engineered Escherichia coli (E. coli), for the first time. Achieving over 99% purification from their parental bacterial cells, minicells are functionalized with magnetic nanoparticle
