Protoporphyrin IX (PpIX) conjugated gold nanoparticle (GNP) was synthesized, characterized, and used for the delivery of a hydrophobic photosensitizer to a cervical cancer cell line. The GNP conjugates have an average diameter of 7nm. The conjugated GNPs were made by a single coupling reaction. Protoporphyrin absorbs radiation at 630nm and catalytically(More)
PURPOSE This study aimed to determine the efficacy of thermotherapy in the presence of gold nanoparticles (GNPs) and microwave (MW) radiation at a frequency of 2450 MHz on the survival of Leishmania major promastigotes and amastigotes. MATERIALS AND METHODS L. major promastigotes (strain MRHO/IR/75/ER) were cultured in RPMI-1640 medium supplemented with(More)
BACKGROUND In this study, the photosensitivity of 5-aminolevulinic acid (5-ALA) conjugated gold nanoparticles (conjugate) has been investigated on the MeL-Rm cell line. METHODS After culture and proliferation of the Mel-Rm cell line, cell toxicity and the suitable cell incubation time of the conjugate were determined. Photosensitivity of the conjugate and(More)
Introduction When a liquid is irradiated with high-intensity and low-frequency ultrasound, acoustic cavitation occurs and there are some methods to determine and quantify this phenomenon. The existing methods for performing these experiments include sonochemiluminescence (SCL) and chemical dosimetric methods. The particles in a liquid decrease the(More)
PURPOSE This study aimed to determine the efficacy of thermotherapy resulting from the presence of gold-gold sulfide nanoshells (GGS) in radio frequency electromagnetic field (13.56 MHz) onthe survival of CT26 colon carcinoma cells. MATERIALS AND METHODS GGS was synthesized and after characterizing and determining the features, the RF-radiation effects on(More)
OBJECTIVES Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. MATERIALS AND METHODS Synthesis and characterization of GGS nanoshells were(More)
