Spatially Resolved Electrochemical Performance in a Segmented Planar SOFC

Spatially resolved electrochemical sensing of chemical gradients.

Chemical gradients drive a diverse set of biological processes ranging from nerve transduction to ovulation. At present, the most common method for quantifying chemical gradients is microscopy. Here, a new concept for probing spatial and temporal chemical gradients is reported that uses a multi-layer microfluidic device to measure analyte concentration as a function of lateral position in a mic...

The spatially resolved refractometer.

PURPOSE To investigate factors controlling the aberrations of the eye, including accommodation, wavelength, and the apodization of the optics of the eye by cone directional selectivity. METHODS We constructed a new implementation of the Spatially Resolved Refractometer (SRR). This is an instrument, based on the Scheiner principle, that allows the rapid psychophysical measurement of the comple...

Integrated circuit-based electrochemical sensor for spatially resolved detection of redox-active metabolites in biofilms

Despite advances in monitoring spatiotemporal expression patterns of genes and proteins with fluorescent probes, direct detection of metabolites and small molecules remains challenging. A technique for spatially resolved detection of small molecules would benefit the study of redox-active metabolites that are produced by microbial biofilms and can affect their development. Here we present an in...
