FFT peak amplitude change percentage of PSi modified by three different types of lectin (ConA, WGA, and UEA) at the presence of different concentrations of (A) E. coli and (B) S. aureus. Control tests: fresh PSi as control 1, GA-modified PSi (without lectin) as control 2 and DI water on ConA-modified PSi as control 3. (R-squared values: 0.9955 for E. coli-ConA, 0.9435 for E. coli-WGA, 0.9709 for E. coli-UEA, 0.9093 for S. aureus-ConA, 0.9950 for S. aureus-WGA, 0.9394 for S. aureus-UEA).
