New confocal microscopy technique enables 3D visualization of colloidal crystal interiors

A team of New York University researchers has created a new way to visualize crystals by peering inside their structures, akin to having X-ray vision. Their new technique—which they aptly named “Crystal Clear”—combines the use of transparent particles and microscopes with lasers that allow scientists to see each unit that makes up the crystal and … Read more

New water-soluble spray makes fingerprints visible in seconds

Scientists have developed a water-soluble, non-toxic fluorescent spray that makes fingerprints visible in just a few seconds, making forensic investigations safer, easier and quicker. Latent fingerprints (LFPs) are invisible prints formed by sweat or oil left on an object after it’s been touched. Traditional forensic methods for detecting fingerprints either use toxic powders that can … Read more
