Cancer Stent Treatment Device Using Nanotechnology

摘要

This application is for a device using aptamers, multiwalled carbon nanotubes (MWCNTs) filled with nanosized iron oxide particles immobilized magnetically on a stent by a magnet and then subsequently killing circulating tumor cells (CTCs) attached to the aptamers by heating the carbon nanotubes with near infrared (NIR) lasers and then release from the stent by removing the permanent magnet and subsequent excretion of the MWCNTs.
