Claim:
1. A method of fabricating a composite PDMS microstructure, comprising: performing a defining step for defining a patterned area having 3-mercaptopropyl trimethoxysilane (MPTMS) on a PDMS substrate; performing a depositing step by placing the PDMS substrate having MPTMS into a vacuum chamber for a deposition time so as to deposit a plurality of Au atoms on the patterned area of the PDMS substrate by a vacuum coating process; and performing a cleaning step for cleaning the PDMS substrate using water so as selectively retain the Au atoms on the patterned area of the PDMS substrate; wherein the vacuum coating process is an evaporation process; wherein the evaporation process comprises: wherein the deposition time is smaller than or equal to 30 minutes.
