Effect of calcium and magnesium on phosphatidylserine membranes: experiments and all-atomic simulations.
Puzzling results suggest that although these two cations have a similar affinity for PS(-) lipids, they induce substantial structural differences in lipid bilayers containing each of these cations. Expand
A theoretical and experimental approach to the compaction process of DNA by dioctadecyldimethylammonium bromide/zwitterionic mixed liposomes.
Phase diagrams (aggregation and re-entrant condensation phenomena) have confirmed the experimental concentration domains and the isoneutrality conditions and the influence of helper lipid in the compaction process, as well as the optimum choice among those herein chosen. Expand
Silver nanoparticles synthesized with Rumex hymenosepalus extracts: effective broad-spectrum microbicidal agents and cytotoxicity study
Abstract We synthesized silver nanoparticles using Rumex hymenosepalus root extract (Rh). Nanoparticles were subjected to a purification process and final product is a composite of Rh and silverExpand
Charge reversal in anionic liposomes: experimental demonstration and molecular origin.
The robustness of the mechanism to physiological amounts of 1:1 salt suggests a significant impact in processes involving ion-amphiphile interaction in salty water (typical, e.g., of biophysics). Expand
Effect of surface charge on colloidal charge reversal.
It is proved that ionic correlations are behind the appearance of colloidal charge reversal phenomena (especially near the macroion surface), and the effect of the surface charge density on the charge reversal phenomenon is understood. Expand
Interaction between poly(ethylene glycol) and two surfactants investigated by diffusion coefficient measurements.
Dynamic light scattering (DLS) and fluorescence recovery after pattern photobleaching (FRAPP) were used to study the interaction of low molecular weight poly(ethylene glycol) (PEG) with micelles ofExpand
Synthesis of Gold Nanoparticles Using Mimosa tenuiflora Extract, Assessments of Cytotoxicity, Cellular Uptake, and Catalysis
Cell viability and cytotoxicity were evaluated in human umbilical vein endothelial cells (HUVEC), and a moderate cytotoxic effect at 24 and 48 h was found, however, toxicity does not behave in a dose-dependent manner. Expand
Silver Nanoparticles Synthesized with Rumex hymenosepalus: A Strategy to Combat Early Mortality Syndrome (EMS) in a Cultivated White Shrimp
Early Mortality Syndrome (EMS) or Acute Hepatopancreatic Necrosis Syndrome (AHPNS) is a disease produced by gram-negative bacteria Vibrio parahaemolyticus (V. parahaemolyticus), which has causedExpand
Au@Ag Core@Shell Nanoparticles Synthesized with Rumex hymenosepalus as Antimicrobial Agent
The results indicate that AgNPs and Au@AgNPs affect the lag phase and growth rate of Escherichia coli and Candida albicans in a dose-dependent manner, with a better response for Au@agNPs. Expand
Core-Shell Au@Ag Nanoparticles Synthesized with Polyphenols as Antimicrobial Agents
In this work, we used a sequential method of synthesis for gold-silver bimetallic nanoparticles with core@shell structure (Au@AgNPs). Rumex hymenosepalus root extract (Rh), which presents highExpand
