Abstract. The results of the development of a small-size device for spectral-luminescent properties studying of nanoscale porphyrins metal complexes promising for cancer luminescent diagnostics, are presented. The small-size device is based on a highly sensitive sensor-mini spectrometer type FSD-10/2. It is shown that the developed small-size portable device provides a large number of express-studies of spectral-luminescent characteristics of various nanoscale porphyrins metal complexes, in particular, the ytterbium and platinum complexes. The device spectral range of 200–1080 nm allows to explore a wide range of metal porphyrins complexes. At the same time a sufficiently high level of spectral resolution (up to 2–5 nm) is provided. From the luminescence intensity spectra it is possible to make some evaluation of the test compound applicability for early tumors luminescence diagnostics. The spectral-luminescent properties of some samples of ytterbium and platinum porphyrins complexes are studied. Thus, for platinum porphyrins complexes the luminescence maximum is observed in the 650 nm proximity, and for ytterbium porphyrins complexes it is in the 980 nm region.

Key words: porphyrin metal complexes, luminescent diagnostics, fluorescence, fiber-optic probe, mini spectrometer, small-size device, spectral express-diagnostics.
