Now, researchers at Winona State University, Minnesota, have created a design for a ‘glowscope’, a device that could democratise access to fluorescence microscopy – at least partly so. A fluorescence microscope views an object by studying how it reemits light that it has absorbed, i.e. These particles are called fluorophores; the object is infused with them before being placed under the microscope. So a tissue sample collected from a person could be injected with the Hoechst stain and placed under a fluorescent microscope. It’s one thing to set up a fluorescence microscope using products purchased on online marketplaces; actually obtaining all of the materials required is another.
