Article Synopsis
  • - Magnetic nanoparticles (MNPs) are tiny particles (1 to 100 nanometers) made from magnetic materials, possessing unique properties that differ from larger forms; they are increasingly used in various fields such as medicine and technology.
  • - Their small size and magnetic behavior allow for manipulation with external magnetic fields, making them useful for targeted medical applications like drug delivery and imaging, while also being explored for environmental and energy-related uses.
  • - Despite the growing applications of MNPs, there are important concerns about their safety, such as potential toxicity and how they interact with cells, which is becoming a focus of both research and clinical studies.

Introduction: Despite years of efforts to develop new antibiotics for eradicating multidrug-resistant (MDR) and multi-virulent Methicillin-Resistant (MRSA) and Vancomycin-Resistant (VRSA) infections, treatment failures and poor prognoses in most cases have been common. Therefore, there is an urgent need for new therapeutic approaches targeting virulence arrays. Our aim is to discover new anti-virulence therapies targeting MRSA and VRSA virulence arrays.

This work demonstrates the synthesis and characterization of Fe nanoparticles surrounded by a citrate (CIT) matrix prepared at various temperatures and concentrations of metal, capping agent and reducing agent at standard conditions. We study the effect of reactant ratio and reaction temperature on the magnetization of the produced nanoparticles and their crystal structure. We found that for optimal metal concentrations, magnetic saturation increases with increase in the concentration of capping and reducing agents but decreases as the temperature of the reaction increases.

Article Synopsis
  • Enterococcus faecalis is a highly resistant bacterium commonly found in root canal infections, prompting research into innovative disinfection methods like photoinactivation with visible light.
  • This study focused on how femtosecond laser irradiation affects vancomycin-resistant Enterococcus faecalis V583, assessing the impact of wavelength and energy density on bacterial viability and growth.
  • The results revealed that wavelengths of 430 nm and 435 nm at a fluence of 1000 J/cm significantly reduced the bacteria's viability by nearly 98% and emphasized the need to optimize laser parameters for effective bacterial inactivation.
