Rapid Detection of Acinetobacter baumannii Suspension and Biofilm Nanomotion and Antibiotic Resistance Estimation

Biomedicines
Objectives: To develop a system for the rapid detection of Acinetobacter baumannii 173-p1 antibiotic resistance (to ensure reliable fixation of bacteria on a cantilever without losing their nanomotion, to show that nanomotion is due to bacterial ...

Control theory for scanning probe microscopy revisited

Beilstein Journal of Nanotechnology, 2014
We derive a theoretical model for studying SPM feedback in the context of control theory. Previous models presented in the literature that apply standard models for proportional-integral-derivative controllers predict a highly unstable feedback ...

Micro-Sized pH Sensors Based on Scanning Electrochemical Probe Microscopy

Micromachines, 2022
Monitoring pH changes at the micro/nano scale is essential to gain a fundamental understanding of surface processes. Detection of local pH changes at the electrode/electrolyte interface can be achieved through the use of micro-/nano-sized pH sensors ...

Pathogenic Escherichia coli change the adhesion between neutrophils and endotheliocytes in the experimental bacteremia model

Microbial Cell
Septicemia caused by gram-negative bacteria is characterized by high death rate due to the endotoxin release. Since the septicemia depends not only on biochemical aspects of interactions in the system bloodstream, the study of mechanical interactions is ...

Optically induced forces in scanning probe microscopy

Nanophotonics, 2014
Typical measurements of light in the near-field utilize a photodetector such as a photomultiplier tube or a photodiode, which is placed remotely from the region under test.

Cunning Pathogen Tactics: Neutrophil Movement Influenced by Bacterial Attractants in the Experimental Model

Cellular Microbiology
To explore the peculiarities of neutrophil motility, two models of chemoattraction were created: a horizontal model, where a container with bacterial chemoattractant was attached laterally to the endotheliocyte monolayer, and a vertical model, simulating

Autonomous scanning probe microscopy investigations over WS2 and Au{111}

npj Computational Materials, 2022
Individual atomic defects in 2D materials impact their macroscopic functionality. Correlating the interplay is challenging, however, intelligent hyperspectral scanning tunneling spectroscopy (STS) mapping provides a feasible solution to this technically ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
