Introduction: The photo-thermal therapy by nanoparticles has been recently known as an efficient strategy for the cancer treatment. Carbon nanotubes (CNTs) have been extensively studied in biomedical application due to the easy uptake and high permeability in the cells, biocompatibility in biological environments and also their unique electrical, thermal properties. They genera...

Background: Cancer is a complex disease with high rate of mortality. At present, Radiation therapy is one of the most common procedures to overcome this situation. The deficiency of conventional method is the lack of fatal dose transmission into the malignant tissue. Hence, uncertain dose may cause regeneration of cancer cells, and relapse of the disease and invasion of the cancer cells to ...

Objective(s): Photo-thermal therapy (PTT) is a therapeutic method in which photon energy is converted into heat to induce hyperthermia in malignant tumor cells. In this method, energy conversion is performed by nanoparticles (NPs) to enhance induced heat efficacy. The low-cytotoxicity and high optical absorbance of NPs used in this technique are very important. In the present study, titanium di...

several methods have been employed for cancer treatment including surgery, chemotherapy and radiation therapy. today, recent advances in medical science and development of new technologies, have led to the introduction of new methods such as hormone therapy, photodynamic therapy (pdt), treatments using nanoparticles and eventually combinations of lasers and nanoparticles. the unique features of...

The anisotropy of thermal lensing and the photo-elastic effect is characterized for diode-pumped Nd:KGd(WO4)2 crystals cut along the Np and Ng optical indicatrix axes and along its optical axis, O = Ng+43°, at a laser wavelength of 1067 nm. Distortions in the spatial profile of output laser beam are analyzed. The thermal lens is astigmatic; the orientation of its principal meridional planes, A ...

A combination of chemo- and photo-thermal therapy (PTT) has provided a promising efficient approach for cancer therapy. To achieve the superior synergistic chemotherapeutic effect with PTT, the development of a simple theranostic nanoplatform that can provide both cancer imaging and a spatial-temporal synchronism of both therapeutic approaches are highly desired. Our previous study has demonstr...
