Low cost, ultra-thin films of reduced graphene oxide-Ag nanoparticle hybrids as SERS based excellent dye sensors

- Low cost rGO-Ag thinfilm has been prepared by simple liquid/liquid method.
- This interface method is a simple method preferable to other expensive techniques.
- These hybrids rGO-Ag thin films are used for SERS studies for the first time.
- The enhancement factor for R6G is ∼2.3 × 108 with nM detection.
- This rGO-Ag ultrathinfilm substrate can serve as a low cost fluorescent dye sensor.
