Ag-Bi-I rudorffite nanoparticles as a new material for photovoltaics

Noble-metal nanoparticles and carbon-based nanostructures have become the most used subjects in contemporary nanoscience, as they hold great promise for many applications, particularly in nanomedicine. These nanomaterials can be used as platforms with high drug loading capacity and high ability for targeted delivery with localized potency. To keep developing new fabrication and functionalization routes for more efficient employment of the mentioned nanomaterials, controlling and monitoring their interaction with the cell material is necessary. Fluorescence imaging represents a powerful tool for studying cell properties. The optical resolution limit poses a great challenge for the detection and localization of nanomaterials in cell milieu. To preserve the physiological context and to employ non-invasive imaging techniques, the advantageous photophysical properties of the nanomaterials are being explored for probing cell-nanomaterial interaction. In this presentation, we will show the effects of energy transfer, photosensitization, and fluorescence dynamics of nanomaterials on imaging capability. The results from bioimaging of biofunctionalized gold nanoparticles and graphene with cancer liver cells will be presented, together with the preliminary data and future perspective.
