RESUMO
We have systematically investigated the humidity sensing performance and cytotoxic activity of TiO2 nanoflowers synthesized by hydrothermal method. Our result reveals that TiO2 nanoflower based sensor devices show good performance at room temperature with a maximum sensitivity of â¼815% along with a response time of â¼143 s and a recovery time of â¼33 s. Our findings also evaluate the cytotoxic effect of TiO2 nanoflowers on human HepG2 cell lines. The cells are cultured in DMEM medium with varying concentrations of TiO2 nanoflowers for 24, 48 and 72 hours respectively. The results indicate that TiO2 nanoflower doses time dependently suppress the proliferation of HepG2 cell lines.
