The next step is to “further opti- mize the nanostructures of the conducting polymers and understand in more detail the cell-capturing mechanism,” says RIKEN unit leader Hsiao-hua Yu. “We are also currently working on a direct electrical readout of the captured cells, without needing to use a microscope.”
