Building Flower-like Silver Nanomaterials
This picture is a scanning electron microscope image of flower-like silver nanomaterials. Previous research has shown that highly roughened particles, like the silver "flower-like" nanostructures in the image, have optical properties that make them useful for biological tests, including medical diagnostics. Until recently, researchers haven't been sure how to make these particles with these rough outer surfaces.
