Sonochemically produced polydopamine nanocapsules with selective antimicrobial activity.
نویسندگان
چکیده
A facile, versatile, and one-pot sonochemical synthesis of polydopamine (PDA)-nanocapsules from dopamine is reported. The nanocapsules (227 ± 25 nm) can encapsulate hydrophobic substances while retaining the reactivity of PDA toward nucleophilic reactions, enabling facile surface modification for different applications. PDA nanocapsules are nontoxic to mammalian cells while Cu-containing PDA capsules demonstrate strong (99.9%) and rapid (15 min) bactericidal activity.

Background: Gallic acid (GA) is one of the polyphenolic compounds with antioxidant, antimicrobial and radical scavenging activities, which plays a main role in human health against cancer and cardiovascular diseases. GA concentration can be quantitatively measured in food, medicinal plants and body fluids. Materials and Methods: In this study, MnO2 nanosheets were prepared by reducing potassium...
متن کاملProduction of Nanocapsules Using Salvia Leriifolia Leaf Extract and Assessing Effects of the Extract and Nanocapsules Containing the Extract on Microbial Properties in Sausages During the Shelf Life
Background and Objectives: Researches have shown that converting bioactive compounds to nanoscales increases their effectiveness due to their size surface area. Therefore, use of antimicrobial compounds at nanoscales can progress their effectiveness, decreasing their necessary concentrations. Salvia leriifolia, with valuable secondary metabolites such as flavonoids and alkaloids, includes a hig...
متن کاملTriclosan resistance reversion by encapsulation in chitosan-coated-nanocapsule containing α-bisabolol as core: development of wound dressing
The use of nanoparticles may be particularly advantageous in treating bacterial infections due to their multiple simultaneous mechanisms of action. Nanoencapsulation is particularly useful for lipophilic drugs. In this scenario, triclosan is considered a good candidate due to its lipophilicity, broad-spectrum activity, and safety. In the present study, we have developed and characterized an ant...
متن کاملPolylactic Acid—Lemongrass Essential Oil Nanocapsules with Antimicrobial Properties
Polylactic acid was combined with lemongrass essential oil (EO) to produce functional nanocapsules (NCs). The obtained polylactic acid nanoparticles showed antimicrobial activity both with and without the presence of lemongrass oil; however, the presence of EO improved the activity of the NCs. The presence of lemongrass assisted the formation of well-separated NCs and also provided enhanced ant...
