The development of chromophore-carbon nanotube hybrids requires efficient and accurate methods to investigate their photophysical properties. Using the ability of the fluorescence labeling of surface species (FLOSS) technique to determine the density of covalently attached dyes to the surface of

Analytical derivatization (AD) increases the sensitivity of analysis by one to three orders of magnitude, stabilizes labile analytes and converts them into readily extractable products. Using a variant of this technique, we applied solid phase analytical derivatization (SPAD) to fully

Methods for the determination of carbonyl compounds of biological origin by high-performance liquid chromatography were improved by the use of new fluorescent derivatizing agents. Eight fluorescent hydrazides were either synthesized or obtained commercially and compared to dansyl hydrazine (1-dimethylaminonaphthalene-5-sulfonylohydrazide). Four
