Lab-on-a-Chip Pathogen Sensors for Food Safety

There have been a number of cases of foodborne illness among humans that are caused by pathogens such as Escherichia coli O157:H7, Salmonella typhimurium, etc. The current practices to detect such pathogenic agents are cell culturing, immunoassays, or polymerase chain reactions (PCRs). These methods are essentially laboratory-based methods that are not at all real-time and thus unavailable for ...

comprehensive performance study of magneto cantilevers as a candidate model for biological sensors used in lab-on-a-chip applications

in recent years, demand for biological sensors which are capable of fast and accurate detection of minor amounts of pathogens inreal‑time form has been intensified. acoustic wave (aw) devices whose performance is determined by mass sensitivity parametersand quality factor are used in biological sensors as platforms with high quality. yet, current aw devices are facing many challengessuch as the...

Lab-on-a-chip for Urology

In an effort to make a diagnosis of diseases, to assess the treatment outcomes and to evaluate the prognosis, many investigators are currently dedicating themselves to identifying disease markers more easily through a minimally-invasive method using human samples. This has eventually improved the results of critical analysis of individual steps of the various methods. Nevertheless, much scienti...

Optical Multiplexing of Multiple Fluorescence Sensors for Compact Lab-on-a-chip Systems

Frequency domain multiplexing combined with optical waveguides provides a low cost and efficient approach to optical detection in arrayed microfluidic chips by eliminating detection components and improving acquisition time. A waveguide test chip fabricated in PDMS demonstrates 4:1 multiplexing in the readout by utilizing multilayer waveguides.
