An article published in the journal “Nature Nanotechnology” riporta the creation of arrays of nanoprobes small enough to be able to record the internal work of cardiac cells and primary neurons. A team of researchers from the Universities of Surrey and Harvard produced U-shaped nanowire field-effect transistor probes. The possibility of measuring intracellular signals offers new possibilities in the medical field but also technological developments related to human-machine interfaces.

An article published in the journal “Nature Biotechnology” describes a research that uses nanotechnologies based on the exploitation of DNA for medical purposes. A team of scientists from Arizona State University (ASU) and the National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences programmed nanorobots to cut tumorss’ blood supply.

A multi-disciplinary team of scientists and engineers from the MITRE Corporation and Harvard University has taken a step forward that may be the key to the creation of nanomachines. In an article published in the journal “Proceedings of the National Academy of Sciences”, the team led by Charles Lieber, a nanotechnology expert at Harvard University, explains the method of creation of a microscopic processor consisting of hundreds nanotransistors.

On our screens we see images at higher and higher definition, instead IBM created a little movie titled “A Boy and His Atom” using a sort of stop motion animation to create nearly 250 images by placing thousands of individual atoms.
