Programmable Fractal Nanostructured Interfaces for Specific Recognition and Electrochemical Release of Cancer Cells

Topographic recognition of cancer cells is triggered by fractal gold nanostructures (FAuNSs), leading to dramatically enhanced recognition capability and efficient release of cancer cells with little damage. The unique characteristic of FAuNSs is the similar fractal dimension of their surface and that of a cancer cell. The design of fractal nanostructures will open up opportunities for functional design of bio-interfaces for highly efficient recognition and release of disease-related rare cells, which will improve detection in a clinical environment.
