DNA nanosensors

News: Sensor Technology    September 30, 2011
Not all sensors are electronic, or at least if you expand the scope of sensor technology, measurement techniques (which is what sensor technology is about) can also be chemical or physical, among other things. In this case, the sensor is built from DNA and it’s called a DNA nanosensor. The idea behind this particular nanosensor [...]

Tiny generators for tiny sensors

News: Sensor Technology    April 5, 2010
Nanosensors – sensor devices built at the nanoscale (1/100,000 the width of a human hair) – need energy to run. Nanobatteries are one approach under development. Another technology is nanogenerators, nanoscale devices that create electricity from the mechanical energy provided by the environment such as wave action, wind motion, and body movement. Researchers at the [...]

Ultimate sensitivity: Nanosenors

News: Sensor Technology    March 23, 2010
Everything electronic gets smaller, including sensors. Sensors are the devices that gauge your car’s tire pressure. They feel your fingers pinching an iPhone screen. They’re everywhere in modern technology, and soon they will be ultrasensitive and all but invisible – as nanosensors. There are many companies and academic laboratories working on the incorporation of nanotechnology [...]

New: Single molecule sensor array

News: Cell Biology    March 8, 2010
If there is a spectrum that can be detected by sensors, from very small to very big, then the sensor array built by engineers at the Massachusetts Institute of Technology (MIT, Cambridge, USA) can stake a claim for the very smallest – a single molecule. The array uses carbon nanotubes, which are rapidly becoming the [...]
