The main direction of the laboratory's scientific activity is fundamental and applied research for proteomics and medical diagnostics with the use of nanotechnology-based devices. The research is carried out using high-tech equipment based on molecular detectors: atomic force microscopes and a nanowire biosensor. Electron microscopy, mass spectrometric analysis and magnetron sputtering are also employed.
Atomic force microscopy (AFM) provides a fundamental possibility to visualize and count single protein macromolecules and their complexes. By AFM, the following studies of biological objects are performed:

  • AFM visualization of single biological macromolecules and their complexes on an atomically smooth chip surface.

  • Development of fundamental principles of detection of single biomolecules in low-concentration solutions using a combination of AFM and biospecific fishing methods.

  • Development and fabrication of AFM nanobiochips with an array of sensor areas for medical proteomics.

  • Determination of physicochemical properties of single molecules of enzymes (single-molecule enzymology) by AFM.

  • Development of a combination of an atomic force microscope with a mass spectrometer for the identification of objects, adsorbed or immobilized on the chip surface.

APPLIED RESEARCH

  • Development of bioanalytical complexes on the basis of an atomic force microscope for the diagnosis of infectious and oncological diseases at early (asymptomatic) stage. The main units of the complex are represented by an automated atomic force microscope and AFM chips (the chips are fabricated in collaboration with JIHT RAS). On the surface of the chips, an array of sensor areas is formed by magnetron sputtering; each of these areas can contain various types of probe molecules (antibodies, aptamers) against the target molecules to be detected. To date, the efficient detection of biomarkers of diseases in serum using a laboratory prototype of such an AFM-based bioanalytical complex was demonstrated. For the identification of biomolecules on the surface of the AFM chips, a unique system, combining the AFM with mass spectrometry analysis was developed; this system allows one to significantly expand the amount of data obtained.

  • Development of bioanalytical complexes on the basis of highly sensitive nanowire molecular detectors for the diagnosis of infectious and oncological diseases at the level of single viral and microbial particles. The development is performed in collaboration with ISP SB RAS. The laboratory prototype of the complex is a completely Russian development. The efficiency of the detection of biomarkers of diseases in real-time with the use of the nanowire biosensor was demonstrated and confirmed. The prospects of applied research are determined, among other things, by the fact that the manufacturing of chips for the nanowire biosensor is carried out using standard CMOS technology, which is routinely used for the manufacture of microcircuits. Thus, this type of bioanalytical complex is oriented at a large-scale application in routine clinical medical diagnostics.
