Fig. 1
a Silicone wafer (magnification, ×500,000). The silicone serves as a start material for the production of nanopores. b The silicone wafer is coated with gold by dipping method (magnification, ×200,000). c Nanopores are produced on the gold-coated silicone wafer suing photolithography process. The pores are non-homogenous but elongated in shape (magnification, ×200,000)

Fig. 2
The figure shows the nanopores as analyzed using AFM (a). The section analysis of 1-μm2 area of the wafer using AFM shows top view of the nanopores as indicated by the brown region and was used to analyze the depth of the pores (b). The particle analysis of 1-μm2 area of the wafer using AFM shows horizontal view of the nanopores as indicated by the red region and was used to analyze the length, width, and area of the pores in the wafers

Fig. 3
a A skeleton design of a bare metal stent composed of 87 mini cylindrical rods. b SEM pictures of the stent were used to estimate the length of the cylindrical rods. The stent design and the reference stent were used as a reference to calculate the pore volume of the nanopores
