Plasmon sensors of ultra-small concentrations of chemical substances have been developed in the laboratory of the University (Russia). The sensors are used in medicine, pharmaceuticals, safety systems and R&D to improve the sensitivity of IR spectroscopy devices. The detector installed in the system enables to increase 100-10000 detectability for a wide range of organic and inorganic substances. The authors are looking for partners for commercial agreements and technological cooperation.
Traditional methods of IR spectroscopy use unstructured (spectrally-non-selective) substrates. Due to the lack of structure, substrates of this type have a low sensitivity to chemicals. Moreover, due to the use of specially prepared substrates with gold nanomaterials formed on their surfaces, it becomes possible to increase the IR absorption signal several times more at specific wavelengths, increasing the sensitivity of the devices by orders of magnitude.
Innovative aspects are that a new substrate design for IR spectroscopy can significantly increase the resolution of such devices. The development of laboratory staff allows to work with a wider range of substances in comparison with foreign counterparts. The main advantages of the technology are the high resolution of the developed devices and their successful operation in the area of the detection of a wide range of chemicals.
