Real-time label-free affinity biosensors for enumeration of total bacteria based on immobilized concanavalin A
This work presents the results of the use of flow injection surface plasmon resonance and impedimetric affinity biosensors for detecting and enumerating total bacteria based on the binding between E. coli and Con A, immobilized on amodified gold electrode. The single analysis time for both techniques was less than 20 min. Dissociation between the immobilized Con A and the E. coli using 200 mM of g
