Biosensors based on the principles of surface plasmon resonance (SPR) are the effective tool for providing monitoring of pathogenic microorganisms because of their specificity, sensitivity, easy use and short time of analysis. We have developed a portable immunosensor based on SPR and detected Salmonella typhimurium presence and concentration in model solutions. In addition, the methodology of transducer surface pre-treatment has been improved that provides higher sensitivity of the biosensor.
