Abstract

We have developed a fluorescent peptide conjugate (TrpNDIRGDfK) based on the coupling of cyclo(RGDfK) to a new tryptophan-tagged amino acid naphthalenediimide (TrpNDI). Confocal fluorescence microscopy coupled with fluorescence lifetime imaging (FLIM) mapping, single and two-photon fluorescence excitation, lifetime components and corresponding decay profiles were used as parameters able to investigate qualitatively the cellular behavior regarding the molecular environment and biolocalisation of TrpNDI and TrpNDI-RGDfK in cancer cells.
