title = "Smartphone detection of Escherichia coli from wastewater utilizing paper microfluidics",
abstract = "Smartphone detection of E. coli from wastewater was successfully demonstrated using paper microfluidics. Three channels of each paper chip were pre-loaded with BSA-conjugated and anti-is. coft-conjugated beads with varying amount, for negative control, low- and high-range E. coli detection, respectively. Dipping a paper chip into wastewater (or pipetting) led E. coli antigens to travel through paper fibers while effectively filtering out contaminants. E. coli antigens caused immunoagglutination of antibody-conjugated beads (but not BSA-conjugated beads) that were still confined within the paper fibers. This immunoagglutination was quantified by evaluating Mie scattering from the digital images taken at an optimized angle and distance with a smartphone. The detection limit was single-cell-level and the total assay time was less than one minute.",
