Abstract:
A method for producing a micro-carrier of bio-molecule, comprising:patterning pluralities of bar code on a mask using an integrated circuit process, wherein the bar code represents a desired bio-molecule; exposing the bar code to a substrate coated with photoresist using photolithography; etching and removing residual photoresist, wherein the bar code is formed on the substrate, and electroforming said substrate with the bar code to a nickel plate; placing a bead between said nickel plate on which the bar code has been electroformed and a second nickel plate, and compressing the bar code onto the surface of said bead to form a particle with a bar code; coating said bead with a layer of bio-molecule binding material; and combining said particle with the corresponding bio-molecule thereof to produce a micro-carrier with a label.
