The fabrication set-up used for two-photon polymerization of proteins.
A thin albumin-protein structure that has been polymerized in aqueous solution following a spiral track. The width of the lines is about 1 micrometer. The smallest features achieved have been about 700 nm. Proteins can be utilized, e.g. to direct the grow
April 12, 2007 VTT Technical Research Centre of Finland, Tampere University of Technology and Nanofoot Finland Oy have developed a direct-write three-dimensional forming method of biomaterials. The methodology enables fabrication of nano and micrometer scale structures that can be used as parts of tissue engineering scaffolds. The project is funded by the BioneXt Tampere Research Programme.
