Диагностика Escherichia coli с помощью интерференции Фабри-Перо в кремниевых наноструктурах различной морфологии

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