Interlude Two Tools of the Nanosciences

Nanofabrication is building at the ultimate level of finesse. Nobel Laureate and Professor, Rice University In this chapter Tools for Measuring Nanostructures Tools to Make Nanostructures In the year 2000, when they look back at this age, they will wonder why it was not until the year 1960 that anybody began seriously to move in this direction. (See Figure 4.1.) So said Nobel Prize-winning physicist Richard Feynman in a 1960 address commonly considered to have launched nanotechnology, but even...

Shedding New Light on Cells Nanoluminescent Tags

Biologists have any number of reasons to be interested in the movements of particular groups of cells and other structures as they move through the body or even through a sample in a dish. Tracking movement can help them to determine how well drugs are being distributed and how substances are metabolized. But tracking a small group of cells as they move through the body is an essentially impossible task. A needle in a haystack is at least a chunk of dense metal in a mound of light biomass you...
