Background Gold nanorods (GNRs) display unique capacity to absorb and scatter near infrared light, which arises from their peculiar composition of surface plasmon resonances. For this reason, GNRs have become an innovative material of great hope in nanomedicine, in particular for imaging and therapy of cancer, as well as in photonic sensing of biological agents and toxic compounds for e.g. biomedical...
Gold nanorods (GNRs) coated with silica shells, modified with polyethylene glycol (PEG) and finally functionalized with cell penetrating peptides (CPPs) are tested in cellular uptake and cell viability. Different silica shell thicknesses (5 and 30 nm) were chosen and samples were characterized both morphologically by TEM and DLS and optically by spectrophotometry. A murine macrophagic cellular line...
Several attempts were performed to use efficient organic dyes for DSSCs as building integrated (BIPV) windows, that could substitute the more expensive Ru complexes. For this particular application, transparency in the 500 – 600 nm region is a stringent demand that in most cases implied the use a co-sensitizing NIR dye in addition to a dye sensitizer in the visible region. We employed also gold nanorods...
