Efficient Determination of Butylated Hydroxyanisole Using an Electrochemical Sensor Based on Cobalt Oxide Nanoparticles Modified Electrode

A simple and reliable electrochemical sensor based on cobalt oxide nanoparticles modified glassy carbon electrode (GCE/CoOxNPs) for determination of butylated hydroxyanisole is presented here. The nanoparticles were fabricated by electrodepositing method. The modified electrode shows excellent catalytic activity toward butylated hydroxyanisole oxidation in pH 12.0 phosphate buffer solution (PBS...

Phthalates as Emerging Pollutants in Water Environment: Control & Treatment Strategies

An Integrated ISFET Sensor Array

A monolithically integrated ISFET sensor array and interface circuit are described. A new high-density, low-power source-drain follower was developed for the sensor array. ISFETs were formed by depositing Au/Ti extended-gate electrodes on standard MOSFETs, then thin silicon nitride layers using catalytic chemical vapor deposition and/or SU-8 protective layers were formed on the extended-gate el...
