Abstract

Thrombi, e.g. blood clots, in circulatory system pose acute health risk, globally. This research investigated roles of biodegradable starch slurry in advancing biomass machining efficiency. Hard clots (fibrin-rich) prepared from rabbit blood were exposed in vitro concomitantly to ultrasound (1 MHz) and starch slurry. Starch slurry particles (diameter ∼250 nm) yielded a 200% increase in material removal (sonothrombolysis) efficiency. Mechanistic participation of starch, a non-Newtonian material, at the interface of biomass-ultrasonic radiation is discussed. Overall in subtractive biomanufacturing, the role of biodegradable slurry is critical for enhancing material removal efficiency.
