Lensless fluorometer (IMAGE)
Caption
Researchers developed a fluorescence detection system (right) that can provide highly sensitive detection of deadly microorganisms in drinking water, without using any lenses. They are now converting the technology into a lensless dip-in handheld system (left) that could be useful for testing water quality in the traditional natural stone spouts widely used by people in Kathmandu Valley in Nepal (background).
