The IEEE Spectrum blog has an entry today titled "Revolutionary nanotechnology: wet or dry?": Somewhere along the line, the advocates for molecular nanotechnology seem to have lost interest in actually seeing molecular manufacturing come to pass if it meant that the concepts of the mechanically engineered approach (Dry) are abandoned in favor of a biologically engineered method (Wet).
The microgravity tower will allow scientists to study, in a reduced-gravity environment, many diverse phenomena in many fields including nanomaterials, new materials, fire-safety, metallurgy, biotechnology and combustion.
Researchers have successfully manipulated nanomaterials to create a new drug-delivery system that promises to solve the challenge of the poor water solubility of today's most promising anticancer drugs.
Consumer Report has been testing sunscreens for its July issue. Of the eight products tested for nanoparticles, all contained them, but the tests found no correlation between their presence and sun protection.
