Today, 3D nanostructured biofilm manufacturing technology, considered as one of the most attractive frontier techniques in micro and nano manufacturing, has gained a wide application in many fields such as biomedicine and environmental science. As a result, studies on the manufacturing of low-cost, high-yield, standardized, high-resolution and high-precision 3D biomaterials will become the commanding height in the development of next-generation medical devices.
    Traditional methods to produce 3D nanostructured biofilms can be categorized into two kinds, the physical/chemical methods including self-assembly, thermally induced phase separation, etc. and mechanical methods including micro injection molding and etching, etc. These methods are commonly seen in labs since there still exists many technical difficulties through the research process, which are:
  (1)low yield and low production rate resulting that the manufacturing rate needs to be improved;
  (2)low structural stability, low consistency and low flux resulting that the manufacturing standardization ability needs to be improved;
  (3)poor precision on geometric structure and insufficient 3D manufacturing capability resulting that the manufacturing precision needs to be improved;
  (4)complicated manufacturing process and expensive processing facilities。
    Accordingly, the transformation of biomedical research achievements into practical applications requires special equipment with high degree of automation and mechanization, for reducing the equipment cost and professional requirements on the manufacturing staff, to satisfy the vast demands from a large number of users.
    Nano Imprint Technology (NIT) is a low-cost pattern transfer technology used in the batch production of nanostructured patterns. By performing mechanical approaches for one-time forming in mold casting, NIT has no limitation in photon diffraction and electro scattering, does neither need traditional processes of atomic deposition and growth, masking and etching, etc. Therefore, by virtue of its simplicity in manufacturing process, NIT has tremendous advantages to produce 3D nanostructured thin films with periodical patterns.
    This project aims at developing a low-cost, high yield roll-to-roll 3D nanostructured biofilm rapid prototyping equipment, to satisfy the requirements of a vast number of 3D nanostructured biofilms. During the development of the proposed equipment, a series of key problems such as the high-speed precision roll-to-roll motion control, manufacturing of the low-cost high-resolution mold cavity insert, optimization of biocompatible materials will be sequentially solved in order to produce large-area 3D nanostructured biofilms in a high-speed, low-cost way.
