Survismeter has been used to study physicochemical properties of TiO2 NPs.
TiO2 NPs are found to be mono dispersed in biological culture media.
Assessment of DNA-NP interaction is done and mechanism is proposed.
Hyperchromism observed in UV–visible studies indicates electrostatic interaction.
Quenching of EtBr fluorescence suggests intercalation of TiO2 NPs in DNA.
