Super-hydrophobic and super-hydrophilic microscopic surfaces are created using microscopic and repeated geometric patterns (tiny cylindrical posts and channels). These features can be fabricated to work collaboratively on the same surface to promote fluid flowing in some areas or prevent fluid flowing in other areas of a device. The video below shows a collaboration of micro surfaces working together on the same device.
Polymer micro molding is a scalable and economic method of manufacturing devices with microscopic surfaces. Applications requiring these types of surfaces include, bacteria prevention, cellular adhesion, tissue adhesion, tissue or cartilage growth promotion, frictional drag reduction, wear reduction, and seal and barrier strength applications. These surfaces also no longer require secondary coating applications which prevent handling and possible surface contamination, simplify sterilization methods, and save device costs.
