New method combines 3D laser lithography with microfluidic publication in Science Advances Multicolored fluorescent security feature in computer design (left) and its individual levels under the laser scanning microscope (right). (Picture: Frederik Mayer, KIT) Three-dimensional structures on the micro- and nanometer scale have enormous potential for numerous applications. Researchers from the Karlsruhe Institute of Technology (KIT) and Carl Zeiss AG are now presenting an efficient and precise method for printing such structures from various materials in the journal Science Advances : They have integrated a microfluidic chamber into a 3D laser lithography device. With this system they produced multi-colored fluorescent security features that can protect banknotes, documents and branded products from counterfeiting. (DOI: 10.1126 / sciadv.aau9160) From components for data processing with light via optical microlenses, mechanical metamaterials, artificial frameworks for cell cultures to security features for bills or branded products – three-dimensionally printed micro- and nanostructures are conquering […]
