Abstract

A grating-coupled planar optical waveguide sensor is presented for sensing of bacteria by evanescent waves. The waveguide design results in increased depth of penetration into the sample volume, which makes it suitable for detecting micrometer-sized biological objects. We tested the sensor’s performance by monitoring the adhesion of Escherichia coli K12 cells to the sensor surface.
