Abstract
The present invention discloses a set of the nano/micro structured objects capable of interlocking each other, which comprises a first part and a second part. A plurality of protrusions arranged in a matrix are disposed on a surface of the base plate of the first part contacting the second part, and a plurality of cavities are formed on a corresponding surface of the second part. The cross-sectional areas of a portion of each of protrusions and cavities are decreased towards the first part. A plurality of nano-scaled needle objects are formed on the side walls of the each protrusion or each cavity. When the first part and the second part are combined, each of the protrusions is inserted into one of the cavity and the needle objects of the protrusion bunt the inner surface of the cavity or the outer surface of the protrusion.
