β-cyclodextrine coated zinc oxide decorated graphene oxide nano hybrid for photocataylytic, antibacterial, and antifungal applications

Polymer encapsulated zero dimensional/2D hybrids are considered as an efficient multipurpose nanohybrids. Herein, we report a two-step fabrication of β-cyclodextrine (β-CD) stabilized zinc oxide nanoparticles supported over 2D graphene oxide (GO) sheets. The nanocomposite showed band gap in the semiconductor region (∼5.6 eV) which has been confirm by Tauc plot derived from UV–visible spectrum. Fourier transformed infrared (FTIR) spectra of the composites implied its polymer attachment and partial reduction of GO. Time dependent dye degradation has been performed in present of light which showed significant efficacy within 3 h. Moreover, for bacterial and antifungal versatility, the nanohybrids has been tested against both the gram positive and gram negative bacterial strain resulting death of the strains due to generation of reactive oxygen species from the nanohybrid. To effectively prevent bacterial and mold growth, propagation, and survival in medical devices, these results suggest that the nanohybrid could be an ideal alternative for antibacterial, antifungal, and catalytic surface coatings which have an obvious impact not only in biomedical sectors but also in durable fabric coating applications.
