University of Wisconsin-Madison scientist develops a new pin-sized sensor that can detect dangerous chemicals
The scientists at the University of Wisconsin-Madison in the US have developed a novel sensor that can be used in smartphone-sized devices to detect dangerous chemicals based on a unique fingerprint of absorbed and emitted light. Devices called spectrometers are light-splitting instruments that have long been both bulky and expensive, preventing their use outside the ..

Massachusetts Institute of Technology develops optical imaging system ‘DOLPHIN’ for finding tiny tumours
In USA, the researchers at the Massachusetts Institute of Technology (MIT) have developed an imaging system which could be deployed to find tiny tumours, as small as a couple of hundred cells, deep within the body. They used their imaging system, named “DOLPHIN,” which relies on near-infrared light, to track a 0.1-millimetre fluorescent probe through ..
The Indian Space Research Organisation (ISRO) is planning to launch a full-fledged niche Earth observation (EO) satellite — called the Hyperspectral Imaging Satellite (HySIS). The HySIS satellite has critical chip called an “optical imaging detector array’” indigenously developed by ISRO. ‘Hyspex’ imaging will enable distinct identification of objects, materials or processes on Earth by reading the spectrum ..

ISRO to launch a full-fledged niche Earth observation (EO) satellite “HySIS” to enable distinct identification of objects from space
ISRO will soon launch a full-fledged niche Earth observation (EO) satellite called the Hyperspectral Imaging Satellite (HySIS) by using a critical chip it has developed. The purpose of the HySIS satellite is to enable distinct identification of objects from about 600 km in space. The Vis-NIR Hyperspectral payload of HySIS satellite is a hyperspectral imaging ..

At present, one isotope gold Au-198, (half-life 2.7 days) is used in some cancer treatments and for treating other diseases. Recently, an international team, led by University of Western Australia and Griffith University, has described how using two imaging techniques can allow scientists to see where gold complexes used in potential chemotherapeutic treatments end up ..
