Cantilever resonance frequency and bending. (Left) Mass/stiffness ratios of each of the four cantilevers divided in three groups: clean chip, after functionalization by micro-spotting, and after the addition of BAM antibody . The values are an average of eight experiments (104, 108, 112, 116, 117, 118, 119, and 120). (Right) Average bending values (μm) of cantilever tip relative to the chip body surface. Values are averages obtained from five experiments (116, 117, 118, 119, and 120).
