Differences in bacteria nanomotion profiles and neutrophil nanomotion during phagocytosis

open access: yesFrontiers 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

open access: yesBiomedicines, 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

open access: yesMicroorganisms, 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

open access: yesNew 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

open access: yesMicro, 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

Ultrafast scanning probe microscopy [PDF]

open access: yesApplied Physics Letters, 1993
We have measured the response of the tunneling gap of a scanning tunneling microscope to excitation by a subpicosecond electrical pulse. Combining ultrashort laser pulses techniques with scanning tunneling microscopy (STM), we have obtained simultaneous 2-ps time resolution and 50-Å spatial resolution. This is a 9 orders of magnitude improvement in the

Scanning Probe Microscopy: From Living Cells to the Subatomic Range

open access: yes, 2010
In this chapter the reader will be introduced to scanning probe microscopy of samples varying by seven orders of magnitude in size (Fig. 13.1). The largest samples presented are living cells, measuring some hundreds of micrometers.

Combined Kelvin probe force microscopy and secondary ion mass spectrometry for hydrogen detection in corroded 2024 aluminium alloy [PDF]

open access: yes, 2013
The capability of Kelvin probe force microscopy (KFM) to detect and locate hydrogen in corroded 2024 aluminium alloy was demonstrated. Hydrogen was introduced inside the 2024 alloy following a cyclic corrosion test consisting of cycles of immersion in 1 ...
