The biosensor «sees» several gas molecules in a billion molecules of water

Russian scientists have created prototype sensor with a biopolymer film capable of recording hydrogen sulphide in concentrations of 1:1,000,000,000. The luminescent sensor system is based on protein complexes, due to the introduction into the biopolymer matrix of chemically bound phosphor CY3 and myoglobin protein. The authors of the development are scientists from the Far Eastern Federal University and the Far East Branch of the Russian Academy of Sciences (RAS).

The sensitivity of the new molecular biosensor is three times higher than that of conventional sensors. Bioluminofor glows in the presence of a few molecules of a toxic substance in a billion water ones. Due to this fact, the sensor may be used not only for environmental monitoring of water areas and water intake facilities, but also in the field of biomedicine.

For example, the sinsor is able to stimulate long-term memory, has an antispasmodic property and is considered one of the important molecular cardioprotectors. A new hypersensitive system opens up opportunities for more detailed studies.

The biosensor currently is being tested in the laboratory.
