High Sensitivity SERS Substrate with Femtosecond Laser-Printed Nanohole Arrays

High Sensitivity SERS Substrate with Femtosecond Laser-Printed Nanohole Arrays

This article presents a novel method for fabricating repeatable and uniform surface-enhanced Raman scattering (SERS) substrates. The proposed method consists of two steps: (1) the fabrication of nanohole arrays using advanced femtosecond laser-induced two-photon polymerization (TPP) technology; and...
