Almost as sensitive as a dog's nose

New sensor for SERS Raman spectroscopy

02-09-2013

Scientists at ETH Zurich and the Lawrence Livermore National Laboratory (LLNL) in California have developed an innovative sensor for surface-enhanced Raman spectroscopy (SERS). Thanks to its unique surface properties at nanoscale, the method can be used to perform analyses that are more reliable, ...

Why gold nanoparticles can penetrate cell walls

Gold nanoparticles with special coatings can deliver drugs or biosensors to a cell's interior without damaging it

26-08-2013

Cells are very good at protecting their precious contents — and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective way of doing so, discovered in 2008, is to use nanoparticles of pure ...

‘Forensic fingers’ for crime scene investigation

14-08-2013

A team of scientists in the United States has developed a wearable fingertip sensor to enable crime scene investigators to rapidly detect explosives and gunshot residue. Traditional forensic analysis is typically carried out in a central laboratory, which requires time-consuming processes such as ...

Sensors monitor cells at work

03-07-2013

Transport proteins are responsible for moving materials such as nutrients and metabolic products through a cell's outer membrane, which seals and protects all living cells, to the cell's interior. These transported molecules include sugars, which can be used to fuel growth or to respond to ...

Nanotechnology helps track and improve drug action in pancreatic cancer

13-06-2013

UK and Australian scientists have been able to show ways in which we can markedly improve drug targeting of solid tumours, using tiny 'biosensors' along with new advanced imaging techniques. In real time and in three dimensions, these technologies can show us how cancers spread and how active ...

A safe route to a needle-free diabetes sensor

11-06-2013

Research reports a new metal oxide semi-conductor (MOS)-based breath test for diabetes that can be produced safely and at a low cost, without employing flame spray pyrolysis. Flame spray pyrolysis is the usual method for making MOS-based sensors, but it can involve unsafe processing procedures ...

Self-powered herbicide biosensor

31-01-2013

A self-powered biosensor that can detect herbicides in water has been developed by US scientists. Most commercial herbicides act by inhibiting photosynthesis in plants. Unfortunately, photosynthetic aquatic microorganisms and aquatic plants are also similarly affected, which is why herbicides are ...

Sensor technology for efficient and portable gas detection devices

25-01-2013

Gas sensors developed in a European project now enable the implementation of cheaper and smaller instruments with equal or higher speed and sensitivity than current laboratory-grade instruments. Production of super-sensitive and portable measuring devices is made possible by a photo-acoustic gas ...

Destination China as Level Sensors and Transmitters Markets Make a Comeback

Increased investments in manufacturing and greater automated production to fuel demand in emerging economies

14-11-2012

Multiple advantages will fuel the continued dominance of non-contact level sensors in the global level sensors and transmitters markets. Overall, the market will make a recovery on the back of revived projects that were shelved or postponed during the economic recession. However, economic turmoil ...
