A new nanotech "wiretap" can enter living cells and monitor their activities in real time, scientists say. Scientists used silicon nanowires to create hairpin-shaped conducting transistors that are smaller than a typical virus. The transistors are able to float freely inside the cells and "listen in" on crucial biological functions. When put to the test inside cultured chicken heart cells, the transistors recorded changes in the cells' heartbeat-driving electrical output. (source: news.nationalgeographic.com)
