Certified reference materials (CRM) composed of propyl (11383-2019) and isopropyl (11384-2019) alcohols solutions were created for validation of measurement procedures and control of measurement errors of measurement results of mass concentrations of toxic substances (alcohol) in biological objects (urine, blood) and water. Two ways of establishing the value of the certified characteristic – mass consentration of propanol-1 or propanol-2 have been studied. The results obtained by the preparation procedure and comparison with the standard are the same within the margin of error.

A device was developed for searching of optimal parameters for the treatment of biological objects by an alternating magnetic field, where the optimal parameters are determined through automated analysis of the dependencies of the physical characteristics of biological liquids obtained from those biological objects on the frequency and strength of the field.

A low-coherence interference microscope arrangement based on a common path shearing interferometer is proposed to obtain differential phase patterns of biological objects. The phase stepping method is used to reconstruct such patterns. Results are presented for experiments to study human blood erythrocytes.

A microwave radio thermometer for determining the temperature of local sections inside a biological medium is described. The basic operating principle is a modification of the zero-measurements method.

We consider peculiarities in the use of an interference microscope in the research of biological objects (cells) and measurement of the parameters of homogeneous, nonhomogeneous, and dynamic biological micro-objects.

The potential for the study and determination of the optical constants of strongly scattering biological objects using spectroscopic analysis of repeated attenuated total internal reflection (ATR) is considered. The optical circuits of repeated attenuated total internal reflection adapters intended for joint operation with infrared-range spectrophotometers are presented.

We give an analysis of the state-of-the-art and trends in development of instrumental methods for detection and amplification of the physical fields of biological objects in different wavelength ranges.

We consider a method for determing the electrical conductivity of a biological object in an aqueous medium from the distortion it introduces into the electric field associated with a current.

A classification is made of the main biological problems associated with the registration of working ferromagnetic particles injected into, by special methods (or attached to) biological tissues. A method using eddy current transducers is proposed, and apparatus described for recording and measurement of the biological object being studied.

We propose a simple device for scanning moving surfaces of biological objects. The device is based on the use of eddy-current sensors made in the form of an Archimedean spiral, and can be used to measure the movement parameters for different parts of the body in humans or animals.
