Nb₂C and Ta₂C MXenes exhibit remarkable SERS performance with the enhancement factors of 3.0 × 10⁶ and 1.4 × 10⁶, which is synergistically enabled by the PICT resonance enhancement and electromagnetic enhancement.
The excellent SERS sensitivity endows Ta₂C MXene with the capability to sensitively detect and accurately identify the SARS-CoV-2 spike protein, which is beneficial to achieve real-time monitoring and early warning of novel coronavirus.
