Outline of Final Research Achievements

The ultra-high-speed sensor for a quantitative analysis of free radicals has been proposed for micro-chemical analysis, quantitative analysis of active oxygen species and monitoring the deterioration of functional materials. In this work, the parametric method of electron spin resonance has been proposed. The electron spin resonance spectrum by proposed method is obtained with the voltage sweep. The sensor is implemented by employing the standard LSI technology (CMOS 180nm) and evaluated. The spectra of commercially available radicals such as DPPH and TEMPOL are successfully obtained by the prototyped free-radical sensors.
