3D-Printed Microfluidic Device for the Detection of Pathogenic Bacteria Using Size-based Separation in Helical Channel with Trapezoid Cross-Section
TL;DR: A facile method has been developed to detect pathogenic bacteria using magnetic nanoparticle clusters (MNCs) and a helical microchannel device with or without a sheath flow and the limit of detection was found to be 10 cfu/mL in buffer solution and 100”cfu-mL in milk.
Journal ArticleDOI
Silicon nanowire biosensors for detection of cardiac troponin I (cTnI) with high sensitivity.
TL;DR: Highly sensitive and label-free detection of cardiac troponin I (cTnI), a biomarker for diagnosis of acute myocardial infarction, using silicon nanowire field-effect transistors using honeycomb-like structure to offer improved electrical performance and increased sensing area.
Journal ArticleDOI
Ultrarapid detection of pathogenic bacteria using a 3D immunomagnetic flow assay.
TL;DR: The 3D immunomagnetic flow assay described here provides the fastest high-sensitivity, high-capacity method for the detection of pathogenic bacteria in a large-volume food sample.
Journal ArticleDOI

TL;DR: A facile and sensitive analytical method for the detection of pathogenic bacteria captured by antibody-conjugated magnetic nanoparticles and separated from analyte samples by applying an external magnetic field exhibited high sensitivity toward low concentrations of Salmonella bacteria.
Journal ArticleDOI
Highly sensitive diagnostic assay for the detection of protein biomarkers using microresonators and multifunctional nanoparticles.
TL;DR: Several biomarkers, including interleukin-6, interferon-γ, and alpha-fetoprotein, were selectively detected using arrays of eight silicon microcantilevers, which is superior to the clinical threshold of the biomarkers.
