Abstract: A method for detecting human or animal blood traces on a surface is described. The method is fundamentally based on the reaction of luminol and includes the preliminary operation of atomizing an inorganic powder suspension, such as titania, silica, alumina, hydroxyapatite, or the like, onto the surface to be investigated, after which a composition of luminol, a peroxidic oxidizing agent and an alkaline agent in an amount providing a pH within the range of 10 to 14, is atomized on the surface. A kit for carrying out the detection method of the invention is also described.

Abstract: A silane-modified cyanine of Formula (I) includes the valence tautomers thereof: wherein R1 is a linear, saturated or unsaturated alkyl chain, having 1 to 30 carbon atoms, wherein one or more carbon atoms are optionally substituted by a 4-, 5- or 6-membered aromatic or non aromatic cyclic grouping of carbon atoms; R8 and R9 are independently selected from the group consisting of —OCH3, —OCH2CH3, —OCH2CH2CH3, —OCH(CH3)2, —OCH2CH2OCH3, —Cl, —Br, —I, Formula (II), Formula (III), —N(CH3)2, Formula (IV), Formula (V), methyl, ethyl, propyl, isopropyl. The synthesis method and the use as a fluorescent marker are for inorganic solid supports, for example silica nanoparticles, and/or for biomolecules such as peptides, antibodies, DNA, RNA, etc.
