Yersinia pestis - Opis:
- An early, rapid and definite detection for the presence of biowarfare agents, pathogens, viruses and toxins is required due to their harmful effect to human population. Those potentially encountering the aforementioned include people involved in civil rescue and security, homeland security, military operations, as well as public transportation securities such as airports, metro and railway stations. This work informs the reader of an electrochemical genosensor with an integrated microsystem array combined with microtube fluidics that allows simultaneous detection of different biowarfare agents such as Bacillus anthracis, Brucella melitensis, Bacteriophage lambda, Francisella tularensis, Burkholderia mallei, Coxiella burnetii, Yersinia pestis, and Bacillus thuringiensis var. kurstaki. The chip electrode arrays were modified via coimmobilisation of a 1:100 (mol/mol) mixture of a thiolated probe and a polyethyleneglycol terminated bipodal thiol. Herein, PCR products from relevant biowarfare agents were detected reproducibly through a sandwich assay format with the target hybridised between a surface immobilised probe into the electrode and a horseradish peroxidase-labelled secondary reporter probe, which provided an enzyme based electrochemical signal. Cross-reactivity studies over potential interfering DNA sequences have demonstrated high selectivity using the developed platform producing high-throughput.
