Abstract
Provided is a method of making microarrays that includes providing a substrate with discrete first microfeatures that have a first profile, and depositing vapor-coated materials onto the first microfeatures to form second microfeatures having a second profile that is substantially different from the first profile. Also provided is a method of adding a replication material to the vapor-coated microfeatures to form a mold. Microarrays made by this method can be used as substrates for surface-enhanced Raman spectroscopy (SERS).
