Efficacy and toxicity of plasmonic photothermal therapy (PPTT) using gold nanorods (GNRs) against mammary tumors in dogs and cats.

Plasmonic photothermal therapy (PPTT) was introduced as a promising treatment of cancer. This work was conducted to evaluate the cytotoxic effect of intratumoral (IT) injection of 75μg gold nanorods (GNRs)/kg of body weight followed by direct exposure to 2 w/cm near infra-red laser light for 10min on ablation of mammary tumor in 10 dogs and 6 cats. Complete blood count (CBC), liver and kidney function were checked before the start of treatment and one month after injection of GNRs.

Investigation of factors affecting the synthesis of nano-cadmium sulfide by pulsed laser ablation in liquid environment.

Pulsed laser ablation in a liquid medium is a promising technique as compared to the other synthetic methods to synthesize different materials in nanoscale form. The laser parameters (e.g.

Tissue distribution and efficacy of gold nanorods coupled with laser induced photoplasmonic therapy in ehrlich carcinoma solid tumor model.

Gold nanorods (GNR) within tumor microregions are characterized by their ability to absorb near IR light and emit heat in what is called photoplasmonic effect. Yet, the efficacy of nanoparticles is limited due to intratumoral tissue distribution reasons. In addition, distribution of GNRs to normal tissue might result in non specific toxicity.
