Fabrication and application of polymer based microfluidic devices

Creator:: Koesdjojo, Myra T.
Abstract:: The concept of reducing laboratory operations in scale such that they fit on a microfluidic chip has been met with great enthusiasm. Lab-on-a-chip devices promise to be cost effective to operate due to reduced reagent consumption, have the potential to offer shorter analysis times due to their short path lengths,...

Colorimetric analysis of creatinine in whole blood and urine in a novel paper/polycaprolactone microfluidic device

Creator:: Pommerenck, Joel, Heist, Christopher A., and Remcho, Vincent T.
Abstract:: A novel approach for the colorimetric detection of creatinine in a paper/polycaprolactone hybrid microfluidic device using alkaline3,5-dinitrobenzoate (DNB) is described. The reaction parameters of reagent concentration, alkalinity, and analysis time are optimized for fast reaction times and high color yield. Microfluidic devices incorporating this assay are designed and fabricated to...

Improvements in synthesis and response techniques of ion-selective sensors

Creator:: Pylypiuk, Nataliia
Abstract:: Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...

Design, fabrication and application of a microfluidic nanofiltration module for separation and purification of macromolecules and nanoparticles

Creator:: Rundel, Jack T.
Abstract:: A microfluidic nanofiltration module has been designed, fabricated and applied to the continuous-flow, pressure-driven, post-synthetic purification of macromolecules and nanoparticles via diafiltration using a commercially available organic solvent resistant nanofiltration membrane, STARMEM 122. This module will readily interface with other microscale components within a "nanofactory" for the rapid synthesis, purification...
