New research shows that a portable, battery-operated fluorescence microscope, which costs $240, stacks up nicely against devices that retail for as much as $40,000 in diagnosing signs of tuberculosis.

Gathering 3-dimensional image data is a staple of automated microscopy. Imaging cells in a single plane in biological science is not possible because of inherent unevenness across the sample or the ...
