FIELD: measuring equipment.
SUBSTANCE: invention relates to a measuring technique and can be used in atomic force microscopy for diagnosing nanoscale structures. Magnetically transparent cantilever is connected to electrically conductive magnetically transparent probing needle, which vertex is movably connected by means of two embedded carbon nanotubes with magnetically transparent detachable and autonomous functioning glass sphere with through nanoscale pores, filled with upconverting nanoparticles and magnetic nanoparticles with identical orientation of core-shell structures, which are constantly in control electromagnetic fields. Remote control of excitation of upconverting nanoparticles of nucleus-shell structure and their independent movement along coordinate Z scanning of side walls of nanowells of a biological diagnostic object is carried out using an external excitation source of upconverting nanoparticles operating in the near infrared range and two controlled external oppositely directed synchronized electromagnetic fields.
EFFECT: possibility of scanning nanowells in coordinate Z, depth of which is tens of times greater than the length of the probing needle, electromagnetic wave having an optical wavelength acting on walls of nanowells with simultaneous measurement of electrical characteristics on this stimulating action at one point of the surface of the diagnostic object with coordinates X, Y without affecting adjacent sections.
