Cyanine dyes were prepared as optical contrast media for supporting the surgery of the lamina limitans interna (LLI) of the retina and other structures of the human eye. Their absorption spectra were adapted both to the spectral sensitivity of the human eye and to standard illumination. The contrast could be further amplified by the application of the strong fluorescence of the dyes used. The binding of the dyes to various surfaces was studied. No toxic effects could be detected for the applied dyes.

[email protected] The nanocarriers showed remarkable fluorescence, high singletoxygen quantum yields, and a strong photothermal effect. Flow cytometry suggested that the nanocarriers were efficiently internalized by cancercells. Near infrared thermal imaging and fluorescence self-imaging showed that the i.t. injected [email protected] mainly remained in the tumors, but the intravenous (i.v.) nanocarriers were distributed
