EPCAM and neoplasm: designed nanofibers for circulating tumor cells.[30] Rather than encapsulating the drug, the authors design modifies the nanofibers with an epithelial cell adhesion molecule antibody to epithelial cell adhesion molecules; additionally, the design involves assembling electrode flexible electronic conduits composed of nanofibers and liquid metal‐polymer conductors, enabling nanofibers to specifically capture and kill peripheral cancer cells.
