▎ 摘　　要

NOVELTY - The sensor has a biological sensor main body connected with a wire screen print electrode. The electrode is fixed with a ferro ferric oxide/reduction oxidation graphene sodium alginate compound layer and a teracycline nucleus acid aptamer layer. USE - Core acid aptamer based teracycline detecting biological sensor. ADVANTAGE - The sensor is convenient to manufacture, and has low manufacturing cost and high stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a core acid aptamer based teracycline detecting biological sensor manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a core acid aptamer based teracycline detecting biological sensor manufacturing method.
