Abstract: The present disclosure provides a method for preparing a biochip. The method includes steps of coating a chip with a first solution of biotin to form a biotin-coated chip, wherein the biotin in the first solution is in a first concentration ranging from 0.1 to 1 ?g/ml; providing the biotin-coated chip with a second solution of avidin to form an avidin/biotin-coated chip, wherein the avidin in the second solution is in a second concentration ranging from 0.1 to 100 ?g/ml; and providing the avidin/biotin-coated chip with a third solution of a biotinylated probe to form the biochip, wherein the biotinylated probed in the third solution is in a third concentration ranging from 1 to 3 ?g/ml.
