Visualization of plasmon shift and ΔRGB pattern of the sensor after incubation with five different phytopathogenic bacteria. a Optical image of sensor strips after incubation with five different phytobacteria for 3 h. A sensor strip containing King’s B liquid culture media was included as a control. the RGB value of each “receptor” in the control strip is subtracted from its homologous “receptor” in the test strip (incubated with bacteria), and this differential RGB value is called ΔRGB. b ΔRGB pattern of the five tested phytobacteria obtained with the plasmonic nose after 3 h of incubation. The nanoparticle shape in the “olfactory receptor” is indicated at the top. hpi: hours post incubation
