Influenza is the infectious agent of the seasonal flu. Flu symptoms from influenza infection are similar to the symptoms caused by bacterial upper respiratory tract infections. This similarity causes the inappropriate diagnosis and prescription of antibiotics, leading to drug resistant bacterial strains. Moreover, the limitations of the current viral detection methods prevent the clinical diagnosis of influenza.
The objective of this project is to design a rapid and sensitive influenza diagnostic method based on the highly sensitive Nanostructured microelectrode biosensing assay.
The diagnostic method was designed by selecting probe sequences, controlling the quality of the probes and the sensing chips, and optimizing the deposition conditions. This diagnostic method was shown to be capable of differentiating influenza sequences from non-complementary sequences, detecting influenza sequences in the form of ~1000-nucleotide RNA molecules, sensing the target influenza RNA within a complex mixture of cell lysates, and achieving a clinically relevant detection limit.
