AbstractInterdigital sensors have been widely used for non-destructive applications. New types of planar interdigital sensors have been fabricated with different coating materials to assess the response to Lipopolysaccharide, LPS. All the coatings were selected and optimized to be stable in water, as the measurements take place in water media. Moreover, the coatings have been designed to have available carboxylic or amine functional groups. The use of these functional groups is a widely used technique to specifically binding of biomolecules. The coated sensors were then immobilized with Polymyxin B(PmB) which has the specific binding properties to LPS. This paper will highlight the fabrication process and initial investigations on the sensors' performance based on Impedance Spectroscopy. © 2011 IEEE.
