Electrostatically actuated encased cantilevers
(Beilstein-Institut züur Forderung der Chemischen Wissenschaften, 2018-05)
Background: Encased cantilevers are novel force sensors that overcome major limitations of liquid scanning probe microscopy. By trapping air inside an encasement around the cantilever, they provide low damping and maintain ...
Mosaicos de cargas elétricas e grandes gradientes de potencial em superfícies dielétricas formados pela evaporação de líquidos
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2020-03-06)
This work presents a study on the charge transfer of the automatic micropipette and the glass microsyringe with the grounded and ungrounded metallic part when dripping with different liquids and also when applying different ...
Electrostatic potential as a tool to understand interactions between malaria vaccine candidate peptides and MHC II molecules
One of the most important problems in vaccine development consists in understanding receptor-ligand interactions between Class II Major Histocompatibility Complex molecules (MHC II) and antigenic peptides involved in ...
Studies on electrostatic interactions within model nano-confined aqueous environments of different chemical nature
(Springer, 2017-09)
We study the potential of mean force for pairs of parallel flat surfaces with attractive electrostatic interactions by employing model systems functionalized with different charged, hydrophobic and hydrophilic groups.We ...
Understanding the role of electrostatic interactions on the association of 5-fluorouracil to chitosan-TPP nanoparticles
(2022-05-05)
Judicious design strategies should be considered powerful tools to better control the properties of chitosan (CS) and tripolyphosphate (TPP) particles. This study focused on understanding the role of the charge properties ...
Electrostatic interaction due to patch potentials on smooth conducting surfaces
(American Physical Society, 2013-12)
We evaluate the electrostatic interaction energy between two surfaces, one flat and the other slightly curved, in terms of the two-point autocorrelation functions for patch potentials on each one of them, and of a single ...
Strategies for exploring electrostatic and nonelectrostatic contributions to the interaction of helical antimicrobial peptides with model membranes
(2016-01-01)
Linear antimicrobial peptides, short sequences up to 50 amino acids, rich in basic and hydrophobic residues, are able to form an amphipathic helix when adsorbed onto lipid membranes. Thanks to these characteristics they ...
Zeta Potential Mechanisms Applied to Cellular Immobilization: A Study with Saccharomyces cerevisiae on Dye Adsorption
(2021-01-01)
The wastewater discharge from the textile industry is a major threat to environmental safety, especially for developing countries. In this context, we proposed a biopolymer-based strategy to mitigate this issue. A new kind ...
