Solvent assisted method of microcontact printing |
| 摘要 |
A method of microcontact printing comprises (a) providing an elastomeric stamp comprising a printing surface inked with an ink comprising surface-functionalizing molecules, (b) treating the inked printing surface of the stamp with solvent, and (c) contacting the treated inked printing surface of the stamp to a surface of a substrate. The printing surface of the stamp comprises a first relief pattern, or the surface of the substrate comprises a second relief pattern, or both of the surfaces comprise the relief patterns, and a pattern of surface-functionalizing molecules is transferred to the substrate according to one or both of the relief patterns. |

1. A method of microcontact printing comprising:
(a) providing an elastomeric stamp comprising a printing surface inked with an ink comprising surface-functionalizing molecules that forms a self-assembled monolayer; (b) treating the inked printing surface of the stamp with solvent to provide a treated inked printing surface; and (c) contacting the treated inked printing surface of the stamp to a surface of a substrate; wherein the printing surface of the stamp comprises a first relief pattern printing surface with the treated ink entirely thereon, or the surface of the substrate comprises a second relief pattern, or both of the surfaces comprise the relief patterns; and wherein a pattern of surface-functionalizing molecules is transferred to the substrate according to one or both of the relief patterns. |
