What is it about?
The biosensors are determined as miniaturized integrated devices that include a biological component (antibody, enzyme, receptor protein, nucleic acid, whole cells or portions of tissue) as a sensing element connected to a sensor for detecting a signal. 1D ZnO thin layers obtained by magnetron sputtering react to different bacterial quantity and could be used as bacterial biosensors.

Why is it important?
The sensitivity of 1D ZnO thin layers is from 2-3 bacteria till thousands. It was more indicative to measure the electro potential, than the resistivity of the films. The reaction of the ZnO thin film was strongly dependent on bacterial quantity regardless of the bacterial cell wall structure.https://www.researchgate.net/publication/278414283_Microbial_Sensors_Based_on_Nanostructures/figures
Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. New bacterial sensors could be constructed.
