NANOTECHNOLOGY:
Tweezers for the Nanotool Kit

Chad A. Mirkin

All advances in nanotechnology will continue to rely on the development of new analytical tools for making, manipulating, and probing structures on the nanometer length scale. Scanning probe techniques have revolutionized the field but must be complemented by analogs for macroscopic tools--such as tweezers, pipettes, and pens. A new analytical device--"nanotube nanotweezers"--described by Kim and Lieber (page 2148) is likely to become an integral part of the nanotechnologist's tool kit for manipulating structures with nanoscopic dimensions.
