Patent ID: 7101660

Claim:
A method for fabrication of a colorimetric resonant reflection bio sensor structure comprising: (a) applying a liquid or semi-solid material that is capable of being transformed or cured into a flexible solid over a rigid master structure; (b) transforming the liquid or semi-solid material into a flexible master structure, wherein the flexible master structure has the rigid master structure embossed into a first surface of the flexible master structure; (c) peeling the flexible master structure from the rigid master structure; (d) placing the first surface of the flexible master structure onto a liquid or semi-solid layer, wherein the liquid or semi-solid layer is on a rigid substrate; (e) transforming or curing the liquid or semi-solid layer into a solid layer; (f) peeling the flexible master structure from the solid layer; and (g) applying a high refractive index dielectric film or reflective material over the solid layer, whereby a colorimetric resonant reflection biosensor structure is fabricated.
