Integrated MEMS/NEMS Resonant Cantilevers for Ultrasensitive Biological Detection
Figure 8
Comparison of the tested biotin-to-avidin reaction induced frequency shifts between the cantilever (a) without the PEG modification and (b) with the PEG-silane modification. By the PEG-saline modification method, the suppression of nonspecific adsorption effect on the detection performance is clearly indicated.
