METROLOGICAL ASPECTS OF SCANNING PROBE MICROSCOPY DOI: https://doi.org/10.22184/1993-8578.2026.19.1.32.35
Observing atoms and molecules has become a routine operation in scanning tunneling microscopy since its invention in 1982. Atomic force microscopy allows high-resolution observation of the atomic lattice of crystalline samples. After minimizing the force impact, it was possible to obtain images of atoms and vacancies in atomic force microscopy. The appeal of SPM is its ability to produce images of the micro and nanoworld with record-breaking quality and detail under normal conditions. Hovewer, the question of the limits of SPM remains unanswered. On the one hand, the answer pertains to metrology, on the other, to the fundamental questions of modern physics.

A STRUCTURAL MODEL OF ELECTROSPUN MEMBRANES AND THE GENERATION OF SYNTHETIC SEM IMAGES BASED ON IT DOI: https://doi.org/10.22184/1993-8578.2026.19.1.36.45
A geometric model of electrospun membranes is proposed, describing the spatial arrangement of nanofibers and their layer-by-layer deposition on a collector. The model enables the generation of three-dimensional membrane structures with prescribed fiber parameters and the creation of synthetic SEM images. These images reproduce key features of experimental data and can be used for testing image processing algorithms.

ULTRAMICROSCOPY: POTENTIAL AND APPLICATIONS IN SCIENCE AND TECHNOLOGY DOI: https://doi.org/10.22184/1993-8578.2026.19.1.46.54
The paper examines the capabilities of modern ultramicroscopy – an optical method based on visualizing light scattering from individual nanoobjects. The principles of the method and its differences from classical microscopic and light-scattering techniques are discussed. Specific practical examples demonstrate the wide range of applied problems solved using ultramicroscopy: determining the size and numerical concentration of nanoparticles (including metallic, oxide, and organic ones); estimating density and porosity of nanoparticles; studying aggregation processes and determining stability threshold of colloidal systems (using asphaltenes as an example); detecting nanobubbles; and monitoring purity of liquids. It is demonstrated that this method, combining high sensitivity, the ability to work with native samples, and rapid measurement, is a powerful tool for nanoindustry, materials science, oil and gas industry, and analytical control.

DEPOSITION OF PHOTONIC CRYSTAL FILMS FOR USE IN THE ULTRAVIOLET SPECTRAL REGION DOI: https://doi.org/10.22184/1993-8578.2026.19.1.56.66
This work studies highly ordered photonic crystal films deposition from monodisperse polystyrene colloidal particles with a diameter of 100 nm, targeting the ultraviolet spectral range. We employed and compared two established self-assembly techniques: vertical lifting of the substrate from a colloidal solution and centrifugation (spin-coating). Possibility of varying the number of deposited layers (from a monolayer to several tens) and obtaining different crystallographic orientations of the photonic crystal face-centered cubic lattice relative to the substrate (mainly {111} planes and sometimes {100} planes parallel to the surface) was demonstrated. The obtained films are proposed as cost-effective templates for ultraviolet and soft X-ray nanolithography, fundamental substrates for all-dielectric ultraviolet metasurfaces and nanoantennas, as well as porous matrices for optical sensors in microfluidic systems.

GAS SENSOR BASED ON REGISTRATION OF LECITHIN ORGANIC FILM SWELLING BY ATOMIC FORCE MICROSCOPY DOI: https://doi.org/10.22184/1993-8578.2026.19.1.68.78
Modern gas sensor designs often use a polymer or organic base (film), either pure or filled with nanoparticles of various types. Gas detection can be based on various physical principles: electrical resistance, optical and magnetic properties, etc. A frequently asked question is whether the volume of the sensor film changes (specifically, swells) upon absorption of the gas being detected. This work presents a model study investigating the swelling kinetics of a lecithin-based sensor film upon stimulation with chloroform vapor.

Based on the analysis of unique frames from the world’s first space scanning probe microscope SMM-2000S, which captures changes in the relief of a gold mirror under outer space influence with nanometer precision, a hypothesis was proposed and confirmed in experiments on Earth about the existence of a mechanism for the self-repair of material surfaces in space by sunlight.

INFLUENCE OF INCUBATION OF HORSERADISH PEROXIDASE SOLUTION ON THE HUMAN BODY ON THE ADSORPTION PROPERTIES AND ACTIVITY OF THE ENZYME: DIFFERENCES IN NORMAL STATE AND IN CARDIOVASCULAR PATHOLOGY DOI: https://doi.org/10.22184/1993-8578.2026.19.1.20.31
By atomic force microscopy (AFM) and spectrophotometry (SP), the effect of incubating a horseradish peroxidase (HRP) solution near the wrist of a patient with cardiovascular disease (CVD), as well as near the wrist of a healthy volunteer, on the adsorption properties and activity of this enzyme has been studied. After the incubation, adsorption of HRP aggregates onto freshly cleaved mica, along with the monomeric form of the enzyme, was observed near the wrist of the patient with CVD. No adsorption of HRP aggregates was observed in the case of the healthy volunteer, nor with the control enzyme sample. However, the enzymatic activity of HRP relative to the control sample increased in both cases. Given the wide use of HRP in medical diagnostics and the importance of peroxidases as CVD biomarkers, these experimental findings may be useful in developing new diagnostic systems for human diseases, including CVD and inflammatory conditions.
