Comparison of SAW frequency shifts for different targets. Here, 1 is the response of target DNA (1 µg/mL) having 15 bases, 2 is the response of non-target DNA (1 µg/mL) having 15 bases with one mismatch base, 3 is the response of non-target DNA (1 µg/mL) having 15 bases with two mismatch bases, 4 is the response of non-target DNA (1 µg/mL) having only 4 bases, 5 is the response of non-target DNA (1 µg/mL) having only 3 bases, 6 is the response of target DNA (100 ng/mL) having 15 bases, 7 is the response of target DNA (10 ng/mL) having 15 bases, 8 is the response of target DNA (1 ng/mL) having 15 bases, 9 is the response for BSA, 10 is the response for PBS buffer, adapted with permission from [156].
