Nanotechnology: thinking small.
Nanotechnology--building devices on the atomic scale--may unleash some big scientific advances early in the new millennium. Last January in Arlington, Virginia, nearly 100 representatives from academia, industry, and government laid out the general goals for the next decade of nanotechnology research by U.S. government agencies. Some predict that the potentially rich opportunities in this field...

متن کاملThinking big with small molecules
Synthetic chemistry has enabled scientists to explore the frontiers of cell biology, limited only by the laws of chemical bonding and reactivity. As we investigate biological questions of increasing complexity, new chemical technologies can provide systems-level views of cellular function. Here we discuss some of the molecular probes that illustrate this shift from a "one compound, one gene" pa...
متن کاملThinking Small: Progress on Microscale Neurostimulation Technology.
OBJECTIVES Neural stimulation is well-accepted as an effective therapy for a wide range of neurological disorders. While the scale of clinical devices is relatively large, translational, and pilot clinical applications are underway for microelectrode-based systems. Microelectrodes have the advantage of stimulating a relatively small tissue volume which may improve selectivity of therapeutic sti...
متن کاملVisualizing coronary atherosclerosis in vivo: thinking big, imaging small.
Over the past decade, a keen interest has developed in the imaging of atherosclerosis in patients in vivo. One approach is the direct intracoronary visualization with ultrasound, angioscopy, or more recently, magnetic resonance imaging (MRI). Another, more practical approach is non-invasive imaging with ultrasound, MRI, or radionuclide tracers. In this issue of the Journal, Hamilton et al. (1) ...
