dc.description.abstract | Results show that nanoparticles (NPs) can be biosynthesized at room temperature on the reductive and chelating surfaces of Portobello mushroom spores (PMS). Using this green approach TiOx, Ag, Au, Ag-TiOx and Au-TiOx NPs have been prepared. These were characterized by TEM, SIMS and FTIR-FTIR. TiOx/PMS, Ag-TiOx/PMS, Au-TiOx/PMS and Ag/PMS were active in bacterial inhibition towards Eschericia coli and Staphylococcus aureus, but Au/PMS was not active (suggesting a strong Au-PMS interaction). TiOx/PMS, Ag/PMS and Ag-TiOx/PMS were equally active in an antibacterial and an antifungal sense when tested against Asperillus and Candide. All samples (except Ag-TiOx/PMS and Au-TiOx/PMS) showed an interesting interaction with DNA. We report on the process of fine-tuning these antibacterial properties, progress on making these nanomaterials optically selfindicating and movement towards optical control of their antibacterial activity. Au-TiOx/PMS shows a surface plasmon resonance (SPR) with a maximum at 518 nm that might be useful in following its anti-bacterial properties (i.e. making the bionanomaterial self-indicating). The future of such green bio-nanomaterials is strong. | en_US |
