Sensors and Actuators A: Physical published Yin’s paper on Bioinspired flexible microfluidic shear force sensor skin

There is a need to gather rich, real-time tactile information to enhance robotic hand performance during haptic exploration and object manipulation. Measuring shear forces is useful for grasping and manipulating objects; however, there are limited effective shear sensing strategies that are compatible with existing end effectors. Here, we report a bioinspired and flexible, resistive microfluidic… 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 »
