There is an urgent need for fast, sensitive, and specific detection methods to identify nanoparticles, micro-organisms, bio agents, and toxins in water, blood, food, aerosols and other specimens. This generally involves a laboratory which is expensive, time consuming, and requires skilled personnel. Yet many applications actually require a compact, fast and automated detection system for point-...

[1] As more information about global aerosol properties has become available from remotely sensed retrievals and in situ measurements, it is prudent to evaluate this new information, both on its own and in the context of satellite retrieval algorithms. Using the climatology of almucantur retrievals from global Aerosol Robotic Network (AERONET) Sun photometer sites, we perform cluster analysis t...
