Abstract „Biologically inspired fiber-based nanofluidics: from biology to materials science to engineering“

Butterfly proboscis is a flexible fiber serving as a feeding device for almost 160,000 species of butterflies and moths. Evolution, organization and functionality of this feeding device are poorly understood, though its materials and fluid engineering design is attractive especially for making artificial probes. Using X-ray phase contrast imaging, high speed optical imaging and magnetic probes we were able to discover complex mechanisms of fluid/proboscis interactions. Theoretical studies of wettability of complex shaped proboscises allowed us to understand the role of surface morphology and chemistry of these complex-shaped multifunctional fibers. Using the basic principles of proboscis functioning, we designed and produced flexible fiber-based probes for analysis of minute amount of fluids. Yarns made of nanofibers with double porosity have extraordinary ability to probe, deliver, and sense different fluids. Some bioengineering applications of fiber-based probes will be shown.
