title: Patterned and Specific Attachment of Bacteria on Biohybrid Bacteria-Driven Microswimmers.
abstract: A surface patterning technique and a specific and strong biotin-streptavidin bonding of bacteria on patterned surfaces are proposed to fabricate Janus particles that are propelled by the attached bacteria. Bacteria-driven Janus microswimmers with diameters larger than 3 μm show enhanced mean propulsion speed. Such microswimmers could be used for future applications such as targeted drug delivery and environmental remediation.
