Microfluidic devices, with their potential for portability and rapid analysis times, can bring cost-effective flexibility to modern analytical chemistry applications. However, the design and fabrication of microchips can involve trade-offs between cost, flexibility of configuration, and ideal surface properties or performance. To circumvent these drawbacks, we have developed a hybrid platform consisting of simple microfabricated … Read more
Platinum wire electrodes are commonly used to apply voltage to a fluidic channel. Although the approach is relatively simple, proper preparation of the electrode is very important to prevent field concentrations in the channels. Field concentrations can cause a multitude of problems, including bubble formation, cell lysing, localized heating, chemical reactions, and clogging of channels.
The manipulation of biological samples for diagnostic purposes requires reproducibility and simplicity to be useful in practice. As microfluidic devices transition towards use in medical diagnostics, traditional handheld syringe pumps can be too bulky and laborious for medical procedures that require quick turnaround times. Here, we discuss the evaluation of a portable breadboard platform that … Read more
LabSmith’s LabPackage makes it easy to build, control and monitor simple and complex microfluidic manipulations. This experiment was designed to help you train your laboratory team and test competency on performing a pinched electrokinetic microfluidic injection techniques. It can also be used to test equipment, chips and reagents to ensure that they are working properly. … Read more
He, M.; Herr, A.E. “Microfluidic Polyacrylamide Gel Electrophoresis with In-situ Immunoblotting for Native Protein Analysis.” Analytical Chemistry, 2009, 81, 8177-84. Abstract We introduce an automated immunoblotting method that reports protein electrophoretic mobility and identity in a single streamlined microfluidic assay. Native polyacrylamide gel electrophoresis (PAGE) was integrated with subsequent in situ immunoblotting. Integration of three … Read more
Abstract For domestic and military security, an autonomous system capable of continuously monitoring for airborne biothreat agents is necessary. At present, no system meets the requirements for size, speed, sensitivity, and selectivity to warn against and lead to the prevention of infection in field settings. We present a fully automated system for the detection of … Read more
