Sol-gel materials as possible devices for tissue biomonitoring

Sol-gel techniques became very popular recently due to theirs high chemical homogeneity, lower processing temperatures, possibility of controlling of the size and morphology of particles. We proposed to use the method of hydrolyzing TEOS and emerging different dyes into the solution. Different organic and inorganic dyes will be checked for pH and temperature measurement. Optical absorption spectra are measured, depending of the pH and temperature. The first laboratory tests will be reported. The final compound can be used as an optrode for fiberoptic sensor for tissue biomonitoring.
