The method of fabricating a flexible SPR film comprises the steps of depositing a metal film on a ductile poly (e-caprolactone), PCL-based film having a first length to form a composite PCL-based film; and stretching the composite PCL-based film such that the ductile PCL-based film undergoes an irreversible transformation to form the SPR film exhibiting a second length that is larger than the first length.
