Abstract

A time-resolved multi-spectroscopic image analyzer (TRMSIA) for nonlinear biochemical and reaction diffusion system was developed. The reaction diffusion behavior of Belousov-Zhabaotinsky(BZ) reaction as a probe reaction was studied using this system. The TRMSIA consisted of a light source, multi-spectroscopic part, binocular microscope with a high resolution CCD detector, and computer part. The change in the concentration can be quantitatively measured by absorbance at 10 different wavelengths. It can measure wave velocity by line-profile process using the high-speed time-resolved spectroscopy. As a result, we can analyze quantitatively the dynamics of chemical waves under various conditions with a simple procedure. The TRMSIA-fluorescencce system also proved to be versatile analysis for the biochemical systems, such as the luminous becteria.
