The invention that first enabled researchers to see clear images of living cells was the phase-contrast microscope, which won its inventor, Frits Zernike, a Nobel Prize in 1932. Prior to Zernike's ...

BOSTON - Researchers have developed a new algorithm for recovering the 3D refractive index distribution of biological samples that exhibit multiple types of light scattering. The algorithm helps ...

The use of high-resolution bright-field microscopy is essential for cellular-scale biological research, but this technique has limitations due to low image contrast. Using dyes on the sample can ...

A miniaturized implantable optical device, which is thin enough to lie within the subdural space of a primate brain, can be created using an integrated circuit that provides both fluorescence imaging ...
