Mimicking Nature: Fiber Based Microprobe  by Daria Monaenkova, Marius Chyasnavichys and Taras Andrukh

This image of a butterfly feeding and a nanofiber yarn absorbing a microdrop illustrates a promising application of electrospun nanofiber yarns, an emerging technology being developed by researchers at Clemson. The fiber based probe is designed to absorb droplets of fluid as small as the eye of an ant. This probe could have important biomedical applications, where the extraction and analysis of tiny amounts of fluid from glands, pores, or, ideally, from cells are necessary for accurate and early diagnosis of diseases. The probe under development could sample biofluid without causing pain to the patient! The probe design was inspired by nature, specifically by butterflies which are able to suck very viscous nectar. The nanofiber yarn is able to absorb about half of its own weight in liquid, or possibly more depending on the porosity of the yarn.
