Diagnostics of Escherichia coli Using Fabry-Perot Interference in Silicon Nanostructures of Various Morphologies

This paper explores the potential for diagnosing bacterial presence in biological fluids using
\nFabry–Perot interference in silicon nanostructures with different morphologies. It compares the bacterial
\ndetection capabilities of porous silicon films and silicon nanowires, specifically focusing on the detection
\nof Escherichia coli bacteria. The reflectance spectra of these nanostructures exhibit interference fringes
\nresulting from Fabry–Perot interference. By analyzing changes in the effective optical thickness of the
\nsilicon nanostructures after bacterial deposition, the study concludes that silicon nanostructures with
\nvarying morphologies can be effectively used for bacterial detection
