In the presence of PEG, the solution color changed some Surface plasmon resonance band at ~560 nm indicated the formation of spherical Light with ~38 J/cm 2 fluence and variations in the Curc:AuNPsĬoncentrations (38, 50, 75 and 100% dilutions) were studied. The in vitroĪntibacterial activity of Curc:AuNps was evaluated against Sa, Se, Pa, Ec, CfĪnd Kp using the broth dilution assay. The resulting solutions were characterizedīy UV-Vis and transmission electron microscopy (TEM). This solution was exposed to lightįrom a mercury metal halide lamp. Polyethylene glycol (PEG) in Mili-Q water. Solutions, 3.2 mg of HAuCl 4 was mixed with 1.5 mg Curcumin and To prepare Curcumin gold nanoparticles (Curc:AuNps) Staphylococcus aureus (Sa), Staphylococcus epidermidis (Se), PseudomonasĪeruginosa (Pa), Escherichia coli (Ec), Citrobacter freundii (Cf) and The aim the present study is to investigate the effect of the photodynamicĪction of LED-activated curcumin gold nanoparticles, on cell viability of Vehicle for curcumin delivery increases photodynamic ability. Therefore, The use of gold nanoparticles (AuNPs) as the Photosensitizer in photodynamic therapy (PDT), which is an alternative way to Linked References Pegylated Curcumin with Gold Nanoparticles: Antimicrobial Agent Evaluationīruna Henrique Teixeira 2, Camila Bueno Pacheco Pereira 1, Marcia Regina Franzolin 1, Lilia Coronato Courrol 2ġInstituto Butantan, Laboratório de Bacteriologia, São Paulo, SP, Brazil.ĢUniversidade Federal de São Paulo, Laboratório de Lasers e óptica Biomédica Aplicada, Departamento de Ciências Exatas e da Terra, Diadema, SP - Curcumin isĪ polyphenol derived from the Curcuma longa plant. Curcumin exhibitsĪ variety of therapeutic properties, including antioxidant, analgesic,Īnti-inflammatory, anticancer and antiseptic activities.
