A spectrophotometric flow-based method for the determination of nickel in recreational waters is proposed. In this scenario, strategy was to devise a miniaturized and automatic system based on sequential injection analysis, aiming an expeditious, real-time low-cost determination. For determination, dimethylglyoxime used as color reagent due its selectivity nickel. Considering expected low conce...

Optogenetics has emerged as an exciting tool for manipulating neural activity, which in turn, can modulate behavior in live organisms. However, detecting the response to the optical stimulation requires electrophysiology with physical contact or fluorescent imaging at target locations, which is often limited by photobleaching and phototoxicity. In this paper, we show that phase imaging can repo...
