#Ultra-thin high-speed detector captures unprecedented range of light waves New research at the University of Maryland could lead to a generation of light detectors that can see below the surface of bodies walls and other objects.
Using the special properties of graphene a two-dimensional form of carbon that is only one atom thick a prototype detector is able to see an extraordinarily broad band of wavelengths.
A research paper about the new detector was published Sunday September 07 2014 in Nature Nanotechnology.
Lead author Xinghan Cai a University of Maryland physics graduate student said a detector like the researchers'prototype could find applications in emerging terahertz fields such as mobile communications medical imaging chemical sensing
however in part because it is difficult to detect light waves in this Range in order to maintain sensitivity most detectors need to be kept extremely cold around 4 Kelvin or-452 degrees Fahrenheit.
Existing detectors that work at room temperature are bulky slow and prohibitively expensive. The new room temperature detector developed by the University of Maryland team
and colleagues at the U s. Naval Research Lab and Monash University Australia gets around these problems by using graphene a single layer of interconnected carbon atoms.
Using a new operating principle called the hot-electron photothermoelectric effect the research team created a device that is as sensitive as any existing room temperature detector in the terahertz range
Graphene a sheet of pure carbon only one atom thick is suited uniquely to use in a terahertz detector
The concept behind the detector is simple says University of Maryland Physics Professor Dennis Drew.

UC Berkeley professor of mechanical engineering, has found a way to dramatically increase the sensitivity of a light-based plasmon sensor to detect incredibly minute concentrations of explosives.

The researchers noted that this is much more sensitive than the published results to date for other optical sensors."
"Optical explosive sensors are very sensitive and compact, "said Zhang, who is also director of the Materials science Division at the Lawrence Berkeley National Laboratory and director of the National Science Foundation Nanoscale Science and Engineering Center at UC Berkeley."
"The ability to magnify such a small trace of an explosive to create a detectable signal is a major development in plasmon sensor technology,
"The new sensor could have many advantages over current bomb-screening methods.""Bomb-sniffing dogs are expensive to train
"The sensor could also be developed into an alarm for unexploded land mines that are otherwise difficult to detect,
Unstable and hungry for electrons The nanoscale plasmon sensor used in the lab experiments is much smaller than other explosive detectors on the market.

Latest generation of plasmon sensors The sensor represents the latest milestone in surface plasmon sensor technology,
The ability to increase the sensitivity of optical sensors had traditionally been restricted by the diffraction limit,
The new device builds upon earlier work in plasmon lasers by Zhang's lab that compensated for this light leakage by using reflectors to bounce the surface plasmons back and forth inside the sensor similar to the way sound waves are reflected across the room
Zhang said the amplified sensor creates a much stronger signal than the passive plasmon sensors currently available

#Nanotechnology takes on diabetes A sensor which can be used to screen for diabetes in resource-poor settings has been developed by researchers
A low-cost, reusable sensor which uses nanotechnology to screen for and monitor diabetes and other conditions, has been developed by an interdisciplinary team of researchers from the University of Cambridge, for use both in clinics and home settings.
The sensors use nanotechnology to monitor levels of glucose, lactate and fructose in individuals with diabetes or urinary tract infections
Earlier this year, clinical trials of the sensors were carried out at Addenbrooke's Hospital to monitor glucose levels in 33 diabetic patients.
The sensors developed by the Cambridge team are made using laser light, which organises metal nanoparticles into alternating layers in thin gel films to produce the sensors in a matter of seconds.
When glucose, lactate or fructose concentrations are high in a sample, the sensor changes colour.
The exact concentration can be determined by visually comparing the colour to a reference chart, or the image can be processed automatically by a smartphone application.
the sensors showed improved performance over commercial glucose test strips read by an automated reader,
Additionally, the sensors can be produced at a fraction of the cost of commercially-available test strips.
A single sensor would cost 20 pence to produce, and can be reused up to 400 times,
The use of lasers means that the sensors can be manufactured easily at scale.""These sensors can be used to screen for diabetes in resource-poor countries,
where disposable test strips and other equipment are simply not affordable, "said Ali Yetisen, a Phd candidate in the Department of Chemical engineering & Biotechnology,
"The value of these reusable sensors will be realised when they are mass produced and adopted as a diagnostic tool for routine diabetes screening,
in rapid succession, improved the black coating used for thermal sensors and developed an original and patented method for depositing the coating.
For a flat sensor, the actual average temperature is about 80°C, and in summer the temperature can reach 200°C. Regularly exposed to air and moisture,
the sensor must last for 25 years on a building, which is not so easy.""The durability of our materials at temperatures exceeding 360°C could also be of interest to thermal power plants,
