Harvard researchers use nanoFETs to delicately probe cells
Chemists and engineers at Harvard University have used nanowires in order to make a new type of V-shaped transistor small enough to be used for sensitive probing of the interior of cells. The new device is smaller than many viruses and about one-hundredth the width of the probes which are… »

Biomimicry of nature used for creation of protein nanofabrics
Cells and tissues assemble and organize themselves within a matrix of protein fibers that ultimately determines their structure and function, such as the elasticity of skin and the contractility of heart tissue. These natural design principles have now been successfully replicated in the lab by bioengineers at the Wyss Institute… »

Researchers made DNA molecules that behave as spider robots
A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular “robot” made out of DNA to start, move, turn, and stop while following a DNA track. The molecular robot, nicknamed “spider”, shows… »

New nanoscopic material enables adults to regenerate cartilage
Amateur athletes, professional athletes and people whose joints have just worn out endure health problems, since humans are unable to regenerate cartilage once they are adults and often have to live with painful joints or osteoarthritis. Luckily, Northwestern University researchers are the first to design a bioactive nanomaterial that… »

NOMFET – an organic transistor that mimics a brain synapse
Scientists have great expectations that nanotechnologies will bring them closer to the goal of creating computer systems that can simulate and emulate the brain’s abilities for sensation, perception, action, interaction and cognition while rivaling its low power consumption and compact size. Nanotechnology researchers in France have developed a hybrid nanoparticle-organic… »

Better electronics? Nanoelectronic transistor combined with biological machine
The electronic devices could get a boost in operating efficiency if manmade devices could be combined with biological machines. Lawrence Livermore National Laboratory (LLNL) researchers have developed a versatile hybrid platform that uses lipid-coated nanowires to build prototype bio-nanoelectronic devices. Combined biological components in electronic circuits could enhance bio-sensing and… »

Nanotechnology puts an end to toxic whole-body chemoterapy?
Nanoparticles specially engineered by J. Manuel Perez and his colleagues from University of Central Florida, could someday target and destroy tumors as well as spare the patients from toxic, whole-body chemotherapies. Perez and his team used a drug called Taxol for their cell culture studies because it is one of… »

“Five-dimensional” disks promise storage of 10TB
A team from Swinburne University of Technology in Australia said that by harnessing nanoparticles and a “polarization” dimension to existing technology, storage can be massively boosted without changing the size of a current disc. For the first time researchers from the university’s Centre for Micro-Photonics have demonstrated how nanotechnology can… »
