We present an experimental and analytical study of a novel paper-based device (μPAD) for isotachophoretic sample focusing. Guided by simple heat transfer model, we further developed wax printing fabrication to enable the creation shallow channels, which are critical in providing sufficient dissipation Joule heat, thus use high electric fields short analysis time. This results that is self-contained on piece filter paper does not require any specialized enclosures or cooling devices combat...
Microfluidic paper-based analytical device that utilizes the native high electroosmotic flow in nitrocellulose to achieve stationary isotachophoresis focusing.
In the absence of amplification methods for proteins, immune-detection low-abundance proteins using antibodies is fundamentally limited by binding kinetic rates. Here, we present a new class surface-based immunoassays in which protein-antibody reaction accelerated isotachophoresis (ITP). We demonstrate use ITP to preconcentrate and deliver target surface decorated with specific antibodies, where effective utilization focused sample achieved modulating driving electric field (stop-and-diffuse...
Microfluidic paper-based analytical devices (μPADs) rely on capillary flow to achieve filling, mixing and delivery of liquids. We investigate the use electroosmotic (EO) pumping as a mechanism for dynamic control in devices. The applied voltage can accelerate or decelerate baseline capillary-driven velocity, well be used create tunable valve that reversibly switches off an electrically controlled manner. method relies simple fabrication allows repeated actuation, providing high degree...
We present a new method for accurate detection of sample location in peak mode isotachophoresis (ITP). The technique is based on the design microchannel with multiple constrictions and detecting passage ITP interface through these constrictions. achieve this by monitoring electric current across channel, which exhibits sharp decreases as moves more rapidly higher density show that cross-correlation between signal predefined step function an effective changes slope curve real-time robust to...
