In this paper, we proposed long-lifetime and high-sensitive measurement using fluorescent intensity by compensation of photo-bleaching with the difference compensation for cell measurement. Photo-bleaching of fluorescence is one of the most crucial factors to cause measurement error in physiological measurement. In our approach, difference of fluorescent intensity between imaging time is compensated...
Design and characterization of a new generation of single-photon avalanche diodes (SPAD) array, manufactured by ST-Microelectronics in Catania, Italy, are presented. Device performances, investigated in several experimental conditions and here reported, demonstrate their suitability in many applications. SPADs are thin p-n junctions operating above the breakdown condition in Geiger mode at low voltage...
The 1, 2-bis(quinoline-2-Carboxamido)-4-chlorobenzene (H2Clbqb) was used as an excellent ionophore in the construction of a cadmium(II)-selective PVC-based membrane sensor. The influences of membrane compositions on the potentiometric response of the electrodes have been found to substantially improve the performance characteristics. The best performance was obtained with a membrane composition of...
