Supramolecular Au(I)-Cu(I) Complexes as New Luminescent Labels for Covalent Bioconjugation.

Two new supramolecular organometallic complexes, namely, [Au6Cu2(C2C6H4CHO)6(PPh2C6H4PPh2)3](PF6)2 and [Au6Cu2(C2C6H4NCS)6(PPh2C6H4PPh2)3](PF6)2, with highly reactive aldehyde and isothiocyanate groups have been synthesized and characterized using X-ray crystallography, ESI mass spectrometry, and NMR spectroscopy. The compounds obtained demonstrated bright emission in solution with the excited-state lifetime in microsecond domain both under single- and two-photon excitation. The luminescent complexes were found to be suitable for bioconjugation in aqueous media.

Macroporous methacrylate-based monoliths as platforms for DNA microarrays.

Macroporous monoliths with different surface functionalization (reactive groups) were utilized as platforms for DNA analysis in microarray format. The slides based on a copolymer glycidyl methacrylate-co-ethylene dimethacrylate (GMA-EDMA) have been chosen as well known and thoroughly studied standard. In particular, this material has been used at optimization of DNA microanalytical procedure.
