Slide Coating Takes Temperature on Microscope Slides

May-04-18 An innovative new coating allows researchers to take the temperature of slides while also viewing the sample.

Developed by a team from the University of Buffalo, the coating consists of two layers of gold with a layer of acrylic glass between them. The coating was fabricated to contain ‘exceptional points,’ which are the specific areas where unusual light behavior will occur. A laser will be necessary to use the coating, but co-lead author Ruogang Zhao says a common helium-neon laser could be easily integrated into most microscopes.

Researchers have been trying to combine thermal imaging and microscopy for decades, but the images were usually too low-resolution to use. The new technology, complete with high-resolution images, could significantly streamline the research process.
