Biofouling-Resistant Impedimetric Sensor for Array High-Resolution Extracellular Potassium Monitoring in the Brain

Biofouling-Resistant Impedimetric Sensor for Array High-Resolution Extracellular Potassium Monitoring in the Brain

Extracellular potassium concentration, [K⁺]o, plays a fundamental role in the physiological functions of the brain. Studies investigating changes in [K⁺]o have predominantly relied upon glass capillary electrodes with K⁺-sensitive solution gradients for their measurements. However, such electrodes are unsuitable for taking spatio-temporal measurements and are limited by the surface area of thei...

A novel supramolecular metallogel-based high-resolution anion sensor array.

A novel anion sensor array based on supramolecular metallogels has been developed. It could accurately identify CN(-), SCN(-), S(2-) and I(-) in water. Interestingly, this sensor array is based on a novel design approach termed "competitive coordination control AIE mode" to develop anion-responsive gels which need only one synthesized gelator G1.

High-Resolution Displacement Sensor Using SQUID Array Amplifier

We describe the design and operation principle of a new displacement sensor with a substantial improvement in resolution over what is currently possible. The potential for significant improvement in the measurement of displacement has profound implications for several high-impact gravitational physics and particle physics projects: the detection of gravitational waves, the test of the equivalen...
