According to one aspect of the invention, there is provided a method of forming a film with a lenticular lens array, the method comprising providing a substrate; providing a mold having a plurality of nano-scale to micro-scale cavities that form the lenticular lens array on the substrate; having the mold contact the substrate; and forming the lenticular lens array by allowing portions of the substrate to partially fill the plurality of cavities.


A substrate having compounds disposed thereon for immobilizing a functional molecule, each compound having a chain including: a moiety R that is chemically coupled to the substrate, the moiety R being selected from the group consisting of an ether, ester, carbonyl, carbonate ester, thioether, disulfide, sulfinyl, sulfonyl, and carbonothioyl; and an epoxide-containing moiety that is coupled to the moiety R by a linker including at least one nucleophilic group. Methods of preparing the substrate and use of the substrate are also disclosed
