ES&T publication by Charlie and Prof.Posner was highlighted on Nanowerk

A team led by Jonathan D. Posner, Bryan T. McMinn Endowed Associate Professor at UW, developed a colorimetric assay – similar to a swimming pool test kit – that tests for the presence or absence of nanoparticles in biological and environmental relevant samples with sufficient sensitivity as part per billion concentration levels.

Mark and Kevin published their work on Nucleic Acid detection using Isotachophoresis and Loop-mediated isothermal amplification in Lab on a Chip

Nucleic acid amplification tests are the
 gold standard for many infectious disease
diagnoses due to high sensitivity and specificity, rapid operation, and low limits of detection. Despite the advantages of nucleic acid amplification tests, they currently offer limited point-of-care 
(POC) utility due to the need for complex instruments and laborious sample preparation. We report the development… Read more »

Charlie, Jay and Mark published their work on colorimetric detection of catalytic reactivity of nanoparticles in complex matrices in ES&T

There is a need for new methodologies to quickly assess the presence and reactivity of nanoparticles (NPs) in commercial, environmental, and biological samples since current detection techniques require expensive and complex analytical instrumentation. Here, we investigate a simple and portable colorimetric detection assay that assesses the surface reactivity of NPs, which can be used to… Read more »

Babak and Kelly published their work on improvement in detection limit of lateral flow assays using isotachophoresis in Analytical Chem

Lateral flow immunoassays (LFA) are one of the most prevalent point-of-care (POC) diagnostics due to their simplicity, low cost, and robust operation. A common criticism of LFA tests is that they have poor detection limits compared to analytical techniques, like ELISA, which confines their application as a diagnostic tool. The low detection limit of LFA… Read more »

Babak and Kelly published their work on Isotachophoretic Preconcenetration on Paper-Based Microfluidic Devices in Analytical Chem

Paper substrates have been widely used to construct point-of-care lateral flow immunoassays (LFIA) diagnostic devices. Paper based microfluidic devices are robust and relatively simple to operate, compared to channel microfluidic devices, which is perhaps their greatest advantage and the reason they have reached a high level of commercial success. However, paper devices may not be… Read more »

Dr.Moran & Prof. Posner published a work on the Role of solution conductivity in reaction induced charge auto-electrophoresis

Catalytic bimetallic Janus particles swim by a bipolar electrochemical propulsion mechanism that results from electroosmotic fluid slip around the particle surface. The flow is driven by electrical body forces which are generated from a coupling of a reaction-induced electric field and net charge in the diffuse layer surrounding the particle. This paper presents simulations, scaling,… Read more »
