Researchers Plant Optical ‘Bug’ in Cancer Cells: Detachable photonic nanocavity probes reveal chemical changes...

What if you could plant a listening device in a single cancer cell, a bug that would follow the cell’s movements, eavesdrop on its metabolism and tell you what it’s up to? A group of Stanford University researchers has made a start with a minuscule optical-cavity splinter small enough to insert in single cells and light enough remain embedded as the cells move about and multiply. Gary Shambat and colleagues in Jelena Vuckovic’s Nanoscale and Quantum Photonics Lab built up a gallium arsenide wafer studded with three layers of indium arsenide quantum dots. They then etched away the supporting substrate, leaving a tapering, 200-micrometer-long beam tipped with a blade 20 micrometers long, 400 to 650 nanometers wide, and 220 nanometers thick. The business end of the blade looks like a strut from an infinitesimal Meccano Erector set: it’s pierced by 20 holes (averaging 120 nm a...
