Abstract:

DPN (Dip-Pen nanolithography) is one kind of widely used technique to create nanoscopic patterns of many different materials. F0F1-ATPase is nano scale rotary molecular motor, and it would be an ideal motor or energy providing device in micro/nano system. In this paper, we used DPN technique to create nanoarrays of F0F1-ATPase within chromatophore on gold surface. The feature size of our F0F1-ATPase patterns was 270 nm in average, and there were no more than 20 F0F1-ATPases in each dot. The activity of patterned F0F1-ATPase was demonstrated by its ATP synthesis, which was indicated by the fluorescence change of labeled F1300. The patterned F0F1-ATPase nanoarrays can be further used as biosensor, or power providing system. And precisely patterning F0F1-ATPase with desired size, position and biological activity will accelerate its application in many basic and application research fields.
