TiO2: Au (Titanium Dioxide Conjugated Gold) Crystals as the Biomimetic Oxidase for Rapid and Sensitive Oxalate Detection Combining with Bionic E-Eye

K. Gayathiridevi | G. Pasupathi

Abstract: TiO2: Au (Titanium dioxide conjugated Gold) crystal is a new materials was grown from aqueous solution. Solubility of the crystal has a positive temperature coefficient facilitating growth by slow cooling. Transmission electron microscopy and scanning electron microscopy are used to study the morphological studies of the crystals. Second harmonic generation (SHG) conversion efficiency of up to 2.56 times that of a phase matched conjugate crystal was achieved when the (TiO2: Au) crystal was rotated about c axis, by 9.1 in the clockwise direction. Furthermore, the method was tested by the artificial urine samples, indicating its greater performances for monitoring and diagnosis of urolithiasis in point-of-care applications.

Keywords: oxalate, TiO2-Au conjugate crystals, bionic E-eye and urolithiasis
