Researchers at Rice's Laboratory for Nanophotonics (LANP) said the single-molecule sensor is about 10 times more powerful that previously reported devices."
"Ours and other research groups have been designing single-molecule sensors for several years, but this new approach offers advantages over any previously reported method,
"The ideal single-molecule sensor would be able to identify an unknown moleculeven a very small oneithout any prior information about that molecule's structure or composition.

#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,
