Method for Fabricating Small-Scale, Curved Structures

Abstract

A method is proposed for fabricating small-scale, curved structures. Firstly, a calligraphy paper or filter paper is provided. Liquid-phase material droplets are applied to calligraphy paper or filter paper to form a desired pattern at a contact angle that can form convex curved small-scale structures.

What is claimed is: 
     
         1 . A method for fabricating small-scale, curved structures, comprising:
 providing a calligraphy paper or filter paper;   placing liquid-phase material droplets on mentioned calligraphy paper or filter paper to form a desired pattern; and   wherein mentioned desired pattern has a contact angle to form convex curved small-scale structures.   
     
     
         2 . The method of  claim 1 , wherein mentioned droplets are biomedical test droplets. 
     
     
         3 . The method of  claim 1 , wherein material of mentioned calligraphy paper is PVC (polyvinyl chloride). 
     
     
         4 . The method of  claim 2 , wherein pore size of mentioned calligraphy paper is from 3 to 30 microns and thickness of mentioned calligraphy paper is from 0.15 to 0.3 millimeter. 
     
     
         5 . The method of  claim 4 , wherein mentioned droplets are biomedical test droplets. 
     
     
         6 . The method of  claim 1 , further comprising a step of forming a patterned layer on mentioned calligraphy paper or filter paper prior to mentioned placing liquid-phase material droplets. 
     
     
         7 . The method of  claim 6 , wherein material of mentioned patterned layer comprises ink, carbon powder, toner or wax. 
     
     
         8 . The method of  claim 7 , wherein material of mentioned calligraphy paper is PVC (polyvinyl chloride), 
     
     
         9 . The method of  claim 8 , wherein pore size of mentioned calligraphy paper is from 3 to 30 microns and thickness of mentioned calligraphy paper is from 0.15 to 0.3 millimeter. 
     
     
         10 . The method of  claim 9 , wherein mentioned droplets are biomedical test droplets. 
     
     
         11 . The method of  claim 1 , further comprising a homogeneity test on mentioned desired pattern. 
     
     
         12 . The method of  claim 11 , wherein mentioned droplets are biomedical test droplets.
