Destroying cancer cells by incorporating an artificial biological computer

A complex piece of DNA that acts as a biological computer when it is inserted into cells determines whether or not the cell is a specific type of cancer cell, and if so, initiates the suicide of that cell.

Nanotechnology using designed peptides to build supramolecular structures on surfaces

An algorithm helps design peptides that will self-assemble on a given surface to produce a supramolecular structure of desired geometry.

Engineered bacteria provide new tool for nanotechnology protein design

Engineered bacteria that incorporate unnatural amino acids at multiple positions provide a new tool that may facilitate designing proteins to fold more predictably into molecular machinery components.

New electron diffraction method for nanotechnology determines nanostrucutres in days instead of years

Automated diffraction tomography provides rapid determination of structure of zeolite to atomic precision.

Mechanical force splits molecule that cannot otherwise be split

Ultrasound was used to pull on polymer chains attached to opposite sides of a chemically almost inert molecular ring, splitting it into its two components.

Electric motor made from a single molecule (video)

Electrons from a scanning tunneling microscope cause a molecule of butyl methyl sulfide to rotate about a single sulfur atom attached to a copper surface.

First direct measurement of force generated by an individual synthetic molecular machine

News articles by Jon Cartwright on the Chemistry World news site and by Michael Berger at Nanowerk describe a significant molecular machine milestone achieved by the research groups of David A. Leigh (winner of the 2007 Foresight Institute Feynman Prize in Nanotechnology for Theory) and Anne-Sophie Duwez. The research was reported in Nature Nanotechnology [abstract].… Continue reading First direct measurement of force generated by an individual synthetic molecular machine

Molecular information theory points to robust molecular communications

Those interested in issues of communication at the nanoscale will be interested to learn that the first volume of the new journal Nano Communication Networks, from Elsevier, edited by Ian Akyildiz, is available free of charge. The volume comprises four issues dated March through December of 2010. Just to pick one article out of dozens… Continue reading Molecular information theory points to robust molecular communications
