“…The serum concentration of SAA in normal subjects is o10 mg mL À1 or 12.2 AE 15.0 mg mL À1 , whereas during the onset of swine flu infection, it is significantly elevated to 49.4 AE 14.1 mg mL À1 . [6][7][8] The selection of an immobilization matrix is one of the crucial steps in the development of a biosensor. Various nanomaterials, such as metal oxides, 9,10 metal sulfides, 11 rGO, 12 CNTs, 13 porous carbons, 14 g-C 3 N 4 , 15 etc., have been used as immobilization matrices for the fabrication of biosensors.…”
