Protein has been widely used for fabricating patterned structures since it is one of the most important macromolecules in living organisms,and protein patterns possess potential applications in many fields such as medical diagnosis,tissue engineering,biosensors,and medical screening.At present,there are two fashions to fabricate protein patterns:one is grafting the protein to the microstructure which is prepared by micro-fabrication techniques;the other one is achieving the patterned protein structures directly.Here we provide an overview on current status of the fabrication techniques and the applications of the protein patterns,and then give an outlook on the development of the fabrication techniques and the prospective applications of the protein patterns in future research.
