Presentation title:

Biosensors and its transducer surfaces which experience on thin films via sol-gel method

Abstract:

Biosensors are vital devices for healthcare, environmental monitoring, and food safety. Biorecognition layer where bioreceptors attach on a solid support plays a crucial role in determining the performance of biosensors like sensitivity, selectivity, and response time. Metal oxide thin films have good candidate for biorecognition layers in biosensors due to their unique properties. In our study, SiO₂-TiO₂ thin films, used fiber optic guiding layers of optical DNA biosensors, were fabricated by the sol-gel dip coating technique. Refractive index values of the films were measured using a Metricon 2010 prism coupler after immobilization of ssDNA (single strand DNA) and hybridization of target cDNA (complementary DNA). On the surface of each film, after immobilization and hybridization process, 12 different spots were taken for the measurement and calculation of the mean refractive index values. Increased refractive index values after each step showed the possibility that SiO₂-TiO₂ thin films can be used as a solid support in optical DNA biosensors. Additionally, our current studies on thin film biosensors will be outlined.
