* Microsystem for electrochemical impedance spectroscopy analysis;
* Development of low-conductive growth media;
* Selective phages T4 infection of host cell;
* Paramagnetic beads functionalization with phages and phage-magnetic bacteria capture and concentration.
The detection principle is based on solution conductivity variations that are generated by the viral infection of host cells, their burst for phage progeny release and the concomitant dump of endoplasmic material. As case study, the method targeted Escherichia coli, a common hygiene indicator [2] proof-of-concept results are here presented.
