Combining silicon nanostructures and thermoresponsive polymer brushes, a new nanoscale Velcrolike device is created by Hsiao-hua Yu, Hsian-Rong Tseng, Shyh-Chyang Luo, and co-workers on page 1547. At body temperature, these polymer brushes stick to the tumor cells and capture them with enhanced efficiencies (lower part of the image). When cooled, they release these cells with great viability (upper part of the image), allowing scientists to examine these cells.
