Bio-Robots and Drug Delivery Systems: Cilia and Micro-Needles

This podcast episode provides an overview of two distinct but related advancements in medical technology, primarily focusing on Drug Delivery Systems (DDS) and bio-robotics. The first major topic is the development of AggreBots, bio-robots created by Carnegie Mellon University that utilize organized ciliary movement for autonomous, directional propulsion, addressing the limitations of prior muscle-driven robots by enabling energy self-sufficiency and controlled movement. The second topic details a funding announcement for bionto, a Tohoku University biotech startup, which is developing a patch-type DDS that uses electric osmosis (EOF) and porous microneedles to non-invasively and rapidly deliver large amounts of medication or sample interstitial fluid. Both innovations represent breakthroughs in moving beyond conventional drug administration and bio-actuation methods, with future goals centered on targeted, efficient delivery within the body.
