Preparation of sonoactivated TiO2-DVDMS nanocomposite for enhanced antibacterial activity

•Under different pH systems, a series of modifiers were added to disperse the TiO2 even better.•The new porphyrin sensitizer-DVDMS was introduced for augmenting the sonosensitivity of TiO2.•The designed novel nanohybrid DFT exhibit excellent sonochemical responsiveness and bacterial eradication efficiency.
