A novel polyamine-modified near-infrared fluorescent probe has been developed that allows for selective labeling of living cancer cells in presence of non-cancer cells.
mercapto-functionalized cellulose membranes with preformed Fmoc-amino acid 3-bromopropyl esters yielded membrane-bound amino acids connected via a stable thioether and a cleavable ester bond. This synthesis strategy allows the highly parallel preparation of peptides that can be solubilized from the solidsupport. We apply this approach to the synthesis of novel peptide–cyanine dye conjugates which are
