Detection of Escherichia coli K12 in Water Using Slot Waveguide in Cascaded Ring Resonator

Escherichia coli (E. coli) bacteria can cause serious fatal health problems in human, thus early and quick pathogen detection of these bacteria is a crucial issue in hospitals, food industry, and pharmaceutical companies. Detection of E. coli K12 in drinking water source can be considered of water p...
