Abstract:
Superhydrophobic substrate modifications are an effective way to improve SERS sensitivity by concentrating analyte molecules into a small surface area. However, it is difficult to manipulate low-volume liquid droplets on superhydrophobic substrates. Results To overcome this limitation, we deposited a hydrophilic Ti 3 C 2 T x film on a superhydrophobic ZnO nanorod array to create a SERS substrate with improved analyte affinity. Combined with its interfacial charge transfer properties, this enabled a rhodamine 6G detection limit of 10 −11 M to be achieved. In addition, the new SERS substrate showed potential for detection of biological macromolecules, such as microRNA. Conclusion Combined with its facile preparation, the SERS activity of ZnO/Ti 3 C 2 T x suggests it may provide an ultrasensitive environmental pollutant-monitoring and effective substrate for biological analyte detection.
