Femtosecond Laser-patterned and Au-coated Iron Surfaces as SERS Platforms for Multiple Analytes Detection

We report a single-step approach for fabricating nanogrooves and ripple-like surface structures on iron (Fe) substrate using femtosecond laser irradiation in acetone and different laser processing conditions. Subsequently, these laser-patterned Fe surfaces were used as SERS sensors post deposition of a thin gold (Au) film. The Au coated laser-patterned Fe surface structures exhibited superior detection limits for the dye methylene blue (5 nM) and a pesticide (thiram, 10 µM) with enhancement factor (EFs) of ~106.
