UV-Vis spectroscopy, X-ray photoelectron spectroscopy (XPS) and confocal microscopy were employed for the characterization of the gel particles. Loading of the tris(bipyridyl)ruthenium(II) complexes and the uniformity of the particle size were confirmed. We have studied the Belousov-Zhabotinsky (BZ) reaction in these gel particles. Chaotic oscillating behavior has been observed. Extended Abstract Status: Not Uploaded | ||
