Direct laser writing is a nanofabrication method used to develop three-dimensional nanostructures with almost arbitrary geometry. The fabrication of nanophotonic devices has been the major application of this technology to date. However, recent growth in the adoption of this technology and even commercialization of direct laser writing systems has extended the access of this nanofabrication method to a broader range of researchers including those in the fields of biology and biomimetics. In this review chapter the direct laser writing method and its recent application in developing biomimetic photonic materials are introduced.
