A new type of electron microscope allows nanotech researchers to look at the nanostructures they produce and identify individual atoms and how they are bonded to other atoms.

In “Nanotech Puts Cancer In The Cross Hairs” at Forbes.com, Josh Wolfe describes the approaches of a number of companies developing nanotechnology-based treatments for cancer. Although only a snapshot of an area of intense activity, this overview highlights a number of the important issues. Unfortunately, when it comes to treating cancer, modern medicine is still… Continue reading Many companies trying to treat cancer using nanotechnology
All this week, NanoBusiness Vice President Aatish Salvi debates nanotechnology with the Center for Technology Assessment’s George Kimbrell over at the LA Times online. An excerpt from the former: Realizing the benefits of nanotechnology will take time. That should come as no surprise. Nanotech is trying to solve some of the hardest and most meaningful… Continue reading LA Times features nanotechnology debate
By combining the features of a scanning tunneling microscope (STM) and an atomic force microscope (AFM)–two of the most useful nanotech tools–in a single instrument, IBM scientists have measured the forces necessary to move single cobalt atoms and single carbon monoxide molecules across metal surfaces.
Researchers at IBM are developing DNA nanotechnology to assemble nanoelectronic components into arrays in a bid to replace current lithographic methods of making computer chips.
A properly sized nanoparticle linked to a peptide that binds specifically to cartilage proved an effective drug delivery method when injected into the knees of mice.
Stanford University scientists have achieved new, detailed understanding of how a polymer folds into a unique three-dimensional structure by using an “optical trap” to precisely unfold a functional RNA molecule.
Japanese scientists have succeeded in chemically attaching proteins specifically to the tips of multiwalled carbon nanotubes, avoiding contaminating attachments to the sides of the nanotubes.
Among the most useful tools for nanotechnology are various scanning probe tips for surface modification.
An interview by Nanotechnology.com of the director of the Center for Nanoscale Chemical-Electrical-Mechanical Manufacturing Systems got our attention. I’d give you a URL for this interview but it doesn’t seem to be on the web, only in email. An excerpt: The molecular gate toolbit: This is a toolbit that uses efficient electrokinetic transport in long… Continue reading Top-down nanotechnology reaches downward
