TI - Magnetic biosensor for the detection of Yersinia pestis JO - Journal of microbiological methods VL - 68 SN - 0167-7012 CY - New York, NY PB - Elsevier M1 - PreJuSER-57204 SP - 218 - 224 PY - 2007 N1 - Record converted from VDB: 12.11.2012 AB - A novel type of magnetic-beads based magnetic biosensor is described for the detection of Yersinia pestis. Experiments were performed with the antigen fraction F1 of these bacteria. The magnetic sensor platform offers easy and reliable detection of Y. pestis by the use of magnetic beads for labelling and quantification in a single step due to their paramagnetic features. The system uses antiYPF1 antibodies as capture element on ABICAP columns as core element of the magnetic sensor. Several immobilization methods for antibodies on polyethylene were exploited. The established biosensor has a linear detection range of 25-300 ng/ml Y. pestis antigen F1 and a detection limit of 2.5 ng/ml in buffer and human blood serum. The presented sensor system is small, simple, portable and therefore usable as off-lab detection unit for medical and warfare analytes.
