FIG. 2.

In-air and in-water resonance spectra of MPS-insulated PZT/glass PEMS.

FIG. 3.

A photograph of the polycarbonate fluidics cartridge with the array PEMS mounted in the center. White arrow indication array PEMS location in the semicirculate flow chamber.

Image of FIG. 4.
FIG. 4.

(a) Resonance frequency shift vs time of anti-BA- and BSA-coated PEMS array in BA suspensions of various concentrations, and (b) resonance frequency shift vs time of anti-BA coated PEMS array in BA suspensions in the presence of excess SA and PA cells. Arrows in (a) indicate the times of suspension injection into the flow chamber.

Image of FIG. 5.
FIG. 5.

SEM micrograph of PEMS sensor surface after exposure to (a) sample A , and (b) sample D with a of SA and PA mixture. The solid arrows in (b) indicate BA spores which are cigar-shaped as shown in (a) while the dashed arrows indicate SA cells which are spherical.
