We present a fibre optic biosensor for SARS-CoV-2 detection based on the lossy-mode-resonance (LMR) [6] effect, generated in a single-mode fibre with a thinned cladding and coated by thin-film dielectric with appropriately selected optical properties and thickness. The detection of selected viral structural proteins in the tested sample is ensured by specific bioreceptors. As a result of the interaction with the SARS-CoV-2 antigen, optical response in the short-wave-IR range is observed, and the detection limit does not exceed 1.3*10^2 copies/ml, when converted to the viral load concentration - sufficiently for virus detection even in the first days after infection.
This paper covers research results on development of the cantilevers beams test structures for interconnects reliability and robustness investigation. Presented results include design, modelling, simulation, optimization and finally fabrication stage performed on 4 inch Si wafers using the ITE microfabrication facility. This paper also covers experimental results from the test structures characterization.
