We report fabrication of microstructures made of protein by femtosecond (fs) laser direct writing (LDW) that exhibit fluorescence. Although fs laser multi-photon cross-linking has been recently applied to fabricate microstructures of proteins, only limited types of proteins have been demonstrated for fabrication. Since fluorescence is a common tool to label or track cells for many biomedical applications, fluorescent proteinaceous microstructures might render a useful addition to those biomedical applications.
