DISSOCIATIVE LUMINESCENT NANOSENSOR Russian patent published in 2011 - IPC G01N21/62 B82B1/00 

FIELD: instrument making.

SUBSTANCE: nanosensor comprises semi-conductor nanocrystals (quantum points, QP) joined by means of coordination joint to molecules of organic dye into complex, in which own luminescence of QP is not available. Nanosensor comprises hydrophobic QP and molecules of hydrophobic organic dyes, extracting ions of metals and (or) ions of hydrogen from water medium into hydrophobic medium, forming complexes with them. At that nanosensor may be placed into thin hydrophobic polymer film, allowing for diffusion of metal ions and hydrogen ions, or may be arranged in hydrophobic liquid medium, having phase difference with analysed sample.

EFFECT: improved sensitivity and simplified procedure of nanosensor making.
