Rapid fingerprinting of bacterial species using nanocavities created on screen-printed electrodes modified by β-cyclodextrin.

ABSTRACT: Rapid and precise identification of infectious microorganisms is important across a range of applications where microbial contamination can cause serious issues ranging from microbial resistance to corrosion. In this paper a screen-printed, polymeric β-cyclodextrin (β-CD) modified electrode, affording nanocavities for inclusion of the analytes, is shown as a disposable sensor capable of identifying bacteria by their metabolites. Three bacterial species were tested: two from the Pseudomonas genus, Pseudomonas fluorescens (P. fluorescens) and Pseudomonas aeruginosa (P. aeruginosa), and Serratia marcescens (S. marcescens), a member of the family, Enterobacteriaceae. On biofilm formation each species gave distinct, reproducible, redox fin
