Portable centrifugal microfluidic system for diagnostics in resource-limited settings

2016 IEEE Healthcare Innovation Point-of-Care Technologies Conference, HI-POCT 2016

Phaneuf, Christopher P.; VanderNoot, Victoria A.; Koh, Chung-Yan K.

The threats of disease outbreaks and exposure to biothreat agents, both accidental and intentional, demand field-deployable technology capable of rapid, sensitive, and accurate diagnosis. In order to address these public health concerns, we present a portable centrifugal microfluidic platform and demonstrate sensitive detection protein antigens, host response antibodies, and nucleic acids down to single digit starting copies. The nucleic acid detection utilizes an isothermal amplification via loop-mediated isothermal amplification (LAMP). The platform, which is composed of a compact optical system for laser induced fluorescence (LIF) detection, a quiet brushless motor, and an efficient non-contact heater, offers an easy-to-use system capable of performing sensitive biodetection in a constrained-resource environment.

Modular Automated Processing System (MAPS) for analysis of biological samples

Gil, Geun-Cheol G.; Throckmorton, Daniel J.; Brennan, James S.; Schoeniger, Joseph S.; VanderNoot, Victoria A.; Fruetel, Julia A.; Branda, Steven B.

We have developed a novel modular automated processing system (MAPS) that enables reliable, high-throughput analysis as well as sample-customized processing. This system is comprised of a set of independent modules that carry out individual sample processing functions: cell lysis, protein concentration (based on hydrophobic, ion-exchange and affinity interactions), interferent depletion, buffer exchange, and enzymatic digestion of proteins of interest. Taking advantage of its unique capacity for enclosed processing of intact bioparticulates (viruses, spores) and complex serum samples, we have used MAPS for analysis of BSL1 and BSL2 samples to identify specific protein markers through integration with the portable microChemLab{trademark} and MALDI.
