Roach, P. C. J., Ramsden, D. K., Hughes, J. and Williams, P. (2003) Development of a conductimetric biosensor using immobilised Rhodococcus ruber whole cells for the detection and quantification of acrylonitrile. Biosensors and Bioelectronics, 19 (1). pp. 73-78. ISSN 09565663

A conductimetric biosensor for the detection of acrylonitrile in solution was designed and characterised using whole cells of Rhodococcus ruber NCIMB 40757, which were immobilised into a disc of dimethyl silicone sponge (ImmobaSil™). The biosensor described was capable of the detection and quantification of acrylonitrile in aqueous solution, having a linear response to concentrations between 2 and 50 mM (106–2650 ppm) acrylonitrile. The biosensor has been shown to be reproducible with respect to the data obtained over a number of days, and retains stability for a minimum period of at least 5 days before recalibration of the biosensor is required
