Underwater-transparent nanodendritic coatings are easily fabricated by a three-step template process. After modification with anti-EpCAM, the coatings exhibit the capability for efficiently capturing rare number of cancer cells from whole blood. On the other hand, the unique underwater transparency enables the coatings to directly monitor captured cancer cells by optical imaging.
