Colorimetric Detection of <i>Escherichia coli</i> O157:H7 with Signal Enhancement Using Size-Based Filtration on a Finger-Powered Microfluidic Device

Colorimetric Detection of <i>Escherichia coli</i> O157:H7 with Signal Enhancement Using Size-Based Filtration on a Finger-Powered Microfluidic Device

Although immunomagnetic separation is a useful sample pretreatment method that can be used to separate target pathogens from a raw sample, it is challenging to remove unbound free magnetic nanoparticles (MNPs) for colorimetric detection of target pathogens. Here, size-based filtration was exploited...
