title: A polyamine-modified near-infrared fluorescent probe for selective staining of live cancer cells.
abstract: We report the synthesis of novel polyamine-modified near-infrared (NIR) probes, which show excellent water-solubility and good optical properties. One probe was taken up efficiently by living cancer cell lines whereas no staining of the non-cancer cells was observed.
