Further, a biosensor integrated with microfluidics for liver cancer biomarker testing has been proposed, where resonance shifts of 14.2 GHz and 19 GHz have been detected for (0.02524 μg/mL) and (5 mu/mL) corresponding to Gamma-glutamyl transferase (GGT)-II and Alpha-Fetoprotein (AFP), respectively [126]. This evidence concerns the gene AFP and liver cancer.
