Researchers have published a new DNA nanotech method that uses essentially one tile that self-assembles into a variety of larger three-dimensional shapes.
A developing understanding of non-Watson-Crick interactions places RNA nanotech on a firmer foundation.
It’s very early days as yet, but Japan is moving forward toward the goal of molecular-level machinery to control nanotechnology-based robotic devices for medicine. In the U.S. and Europe, the poorly-informed sometimes ridicule the prospect of such nanotech robots, but visionary goals are apparently okay in Japan. See the report and video at MSNBC from… Continue reading Japan takes lead in medical nanorobots
Bistable rotaxanes might be pressed into service as valves so that nanoparticles only release drugs in desired target areas.
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.
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.
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.
In a virtuoso demonstration of nanotechnology, researchers used a scanning tunneling microscope (STM) to build walls of carbon monoxide molecules to confine electrons on a copper surface so that they resonate like a drum.
