Project title<\/b>:\u00a0Core-shell nanoparticles functionalized with bio-active antimicrobial molecules<\/p>\n

Summary<\/b>:<\/p>\n

As bacteria adapt quickly, current antibiotics become ineffective, leading the era of antibiotics to a close end. Patients in critical care units and those with indwelling devices are the most prone to severe infections, caused by resistant and biofilm related pathogens, which cause more than 70% of the deaths in these patients. Utilizing high amounts of antibiotics impose severe adverse effects against the patient (all antibiotics have different values of toxicity, which can be life-threatening in high concentrations) and also against environment. In this context, clinicians and researchers seek for efficient alternatives to obtain advanced antimicrobials, such as those of natural origin, or innovative synthetic antibiotics able to reduce the selection of resistant bugs, while avoiding harmful effects both against the host and environment. Nanostructured materials functionalized with natural compounds or synthetic antibiotics proved their potential of being efficient against most clinically relevant microorganisms, including resistant bacteria (superbugs) and biofilm-embedded microbes. Core-shell nanosystems could maximize the amount of bioactive compound functionalized\/embedded in the antimicrobial system, to increase its stability, control its release and thus prolong the effect. The\u00a0aim<\/strong>\u00a0of this project is to obtain and investigate the antimicrobial and anti-biofilm effect of uniform core shell magnetite nanoparticles containing bioactive molecules includen in\/on the obtained shell: plant-derived compounds or antibiotics, against relevant laboratory and clinically isolated bacteria strains.<\/p>\n
