Nanoscale tech: Nanopore DNA sequencing status

DNA sequencing by passing a DNA strand through a “nanopore” to detect electrical changes as the strand of DNA is passed through it could speed up DNA sequencing more than 200 times. US physicists at the University of California, San Diego have made a detailed computer simulation of over 100,000 interacting atoms and shown theoretically …

Nanoscale tech: Nanotopography alone can cause Stem cell differentiation

Stem cells can be prompted to develop into bone, instead of muscle or cartilage tissue, if they are grown on a substrate etched with nanoscopic patterns – and no added chemicals – researchers have found. The discovery could lead to longer-lasting artificial implants that are nano-engineered to encourage suitable tissue to develop around them, experts …

Other tech; Lithium ion batteries can also help morph vehicles

Lithium ion batteries can be used for more efficient and larger shape changes than piezoelectrics. Lithium ion batteries expand and contract under tremendous stresses, a must for devices that will be changing the shape of, say, a stiff helicopter rotor that’s also exposed to aerodynamic forces. The electrically activated batteries can operate at low voltages …

Nanoscale, nanomaterials: Battery wire self assembled in viruses

By manipulating a few genes inside these viruses, the MIT team was able to coax the organisms to grow and self-assemble into a functional electronic device. The goal of the work, led by MIT Professors Angela Belcher, Paula Hammond and Yet-Ming Chiang, is to create batteries that cram as much electrical energy into as small …

Project that will try to screen for diseases with biomarkers

Researchers from the Australian Institute for Bioengineering and Nanotechnology at The University of Queensland, the Fred Hutchinson Cancer Research Centre (USA), the University of Washington (USA) and the Seattle Biomedical Research Institute (USA) are forming an international project that aims to investigate and test a set of unique, Australian-owned nanotechnologies that will accelerate advances in …
