Deposition of hydrophilic Ti₃C₂T_x on a superhydrophobic ZnO nanorod array for improved surface-enhanced raman scattering performance.

ABSTRACT:

Background

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 Ti₃C₂T_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
