Ocellatin-PT antimicrobial peptides: High-resolution microscopy studies in antileishmania models and interactions with mimetic membrane systems
(John Wiley & Sons Inc, 2016-12)
Although the mechanism of action of antimicrobial peptides (AMPs) is not clear, they can interact electrostatically with the cell membranes of microorganisms. New ocellatin‐PT peptides were recently isolated from the skin ...
Oligomer-stabilized silver nanoparticles for antimicrobial coatings for plastics
(Elsevier, 2020-10)
The development of composite materials consisting of metal nanoparticles embedded in macromolecular compounds, obtained via in-situ reduction process has attracted research interest. Silver nanoparticles (AgNPs) have been ...
Self-Assembly Stereo-Specific Synthesis of Silver Phosphate Microparticles on Bacterial Cellulose Membrane Surface For Antimicrobial Applications
(Elsevier Science, 2018-09)
In situ self-assembly stereo-specific synthesis of silver phosphate (AgP) microparticles (MPs) in one side bacterial cellulose (BC) membrane surface and loading of ciprofloxacin provides BC scaffolds with a broad-spectrum ...
Synthesis and characterization of Nd(OH)3-ZnO composites for application in photocatalysis and disinfection
(2020-07-15)
Nd(OH)3-ZnO composites were synthesized with three content of Neodymium (1, 3 and 5 wt%) and characterized in terms of their structural, morphological, vibrational, optical, surface, photocatalytic and antimicrobial ...
Antimicrobial and protective effects of non-thermal plasma treatments on the performance of a resinous liner
(2020-09-01)
Objective: Overcoming substantial shortcomings of soft liners as physico-chemical changes and liner-biofilm-related infections remains a challenge in the rehabilitation treatment. In this study, protective non-thermal ...
Silica-based bioactive solids obtained from modified diatomaceous earth to be used as antimicrobial filler material
(Elsevier Science, 2017-05)
It is well known that microbiological spoilage in indoor surfaces has a negative impact on human health. Antimicrobial functionalized materials are intensely studied. The present work seeks the synthesis of eco-friendly ...
Are desensitizing toothpastes equally biocompatible and effective against microorganisms?
(2017-09-01)
The aims of this study were evaluate cytotoxicity, genotoxicity, antimicrobial activity of desensitizing toothpastes compared to a common one and the surface roughness of tooth enamel submitted to brushing with these ...
Race for Applicable Antimicrobial Dental Implant Surfaces to Fight Biofilm-Related Disease: Advancing in Laboratorial Studies vs Stagnation in Clinical Application
(Amer Chemical Soc, 2022-08-08)
Across years, potential strategies to fight peri-implantitis have been notoriously explored through the antimicrobial coating implant surfaces capable of interfering with the bacterial adhesion process. However, although ...
Electrostatic immobilization of antimicrobial peptides on polyethylenimine and their antibacterial effect against Staphylococcus epidermidis
(Elsevier B.V., 2018-04-01)
Staphylococcus epidermidis is a gram-positive bacterium, and one of the most prevalent causes of nosocomial infections due to its strong ability to form biofilms on catheters and surgical implants. Here we explore the ...
Characterization of biosynthesized silver nanoparticles from Streptomyces aqueous extract and evaluation of surface-capping proteins involved in the process
(Elsevier, 2021-04)
Microbial mineralization offers an efficient alternative to obtain metallic nanoparticles. The aim of this work was to synthesize green silver nanoparticles (AgNPs) using the metal resistant strain Streptomyces sp. M7. In ...
