Cells, 2023 The dynamics of neutrophil transendothelial migration was investigated in a model of experimental septicopyemia. Scanning ion-conductance microscopy allowed us to determine changes in morphometric characteristics of endothelial cells during this process.

Differences in bacteria nanomotion profiles and neutrophil nanomotion during phagocytosis
Frontiers in Microbiology, 2023 The main goal of this work is to highlight the connection between nanomotion and the metabolic activity of living cells. We therefore monitored the nanomotion of four different clinical strains of bacteria (prokaryotes) and the bacterial phagocytosis by ...

ROS Production by a Single Neutrophil Cell and Neutrophil Population upon Bacterial Stimulation
Biomedicines, 2023 The reactive oxygen species (ROS) production by a single neutrophil after stimulation with S. aureus and E. coli was estimated by an electrochemical amperometric method with a high time resolution. This showed significant variability in the response of a

Staphylococcus aureus Causes the Arrest of Neutrophils in the Bloodstream in a Septicemia Model
Microorganisms, 2022 Staphylococcus aureus induces the expression of VCAM-1, P- and E-selectins on the endothelial cells of the EA.hy926 cell line but, at the same time, causes the significant suppression of the force and work of adhesion between these receptors of ...

Dark-probe scanning near-field microscopy
New Journal of Physics, 2023 Scanning near-field optical microscopy (SNOM) is a well-known powerful optical technique for visualization of surface nanostructures and fields far beyond the diffraction limit and thus indispensable in material- and nanoscience.

Probing Italy: A Scanning Probe Microscopy Storyline
Micro, 2023 Starting from the late 1980’s, scanning probe microscopy has progressively diffused in Italy until today. In this paper, we provide a brief account of the main historical events and a current picture of the distribution of the active groups. A survey was

ARMScope – the versatile platform for scanning probe microscopy systems
Metrology and Measurement Systems, 2020 Scanning probe microscopy (SPM) since its invention in the 80’s became very popular in examination of many different sample parameters, both in university and industry. This was the effect of bringing this technology closer to the operator.

Scanning frequency comb microscopy—A new method in scanning probe microscopy
AIP Advances, 2018 A method for superimposing a microwave frequency comb (MFC) on the DC tunneling current in a scanning tunneling microscope (STM) is described in which a mode-locked laser is focused on the tunneling junction. The MFC is caused by optical rectification of
