(A) Schematic illustration of the developed protocol for antibody conjugation to the surface of a microfluidic chip. The functional groups that are directly involved in the reactions are shown in red color in the figure, (B) FTIR spectrum of microfluidic chip surface confirming the conjugation of the antibody to the surface using the developed protocol
