Complex, three-dimensional (3-D) structures are regularly constructed using a reliable commercial method of 3-D laser micro- and nanoprinting. In a recent study, Frederik Mayer and co-workers in Germany and Australia have presented a new system in which a microfluidic chamber could be integrated on a laser 3-D lithography device to construct multimaterial structures using more than one constituent material. The new method can eliminate the existing need to transfer between lithography techniques and chemistry labs for a streamlined manufacturing process.
