Quick-freeze/deep-etch transmission electron microscope (TEM) images of a solution of peptides that form peptide nanotubes. There are also vesicles budding off of a nanotube and micelles in the area. Peptide nanotubes may provide new biomaterials for materials science and biology research (see Zhang, p. 1171). Peptide nanotubes prepared by Sylvain Vauthey and Steve Santoso. Artwork rendered by Erin Boyle.
Governments around the world are investing in nanotechnology in the hopes that applications in the biotechnology and chemical industry will help turn faltering economies around.
The current commercial path for nanotechnology ventures mirrors the early evolution of the biotechnology industry, allowing similar strategies toward both technology commercialization and investment opportunities.
Long-lived fuel cells lacking diffusional electron mediators have been created that convert simple and abundant sugars into electricity with >80% efficiency.
Expressing insecticidal proteins from sources other than Bacillus thuringiensis in crop plants should reduce the likelihood for development of insect resistance to toxins.
