Biocompatible gold nanoparticles (AuNPs) are particularly interesting for photo-thermal therapy (PTT) of cancer treatment because their ability to convert light into heating efficiently. Nevertheless, the random accumulation AuNPs in tissues, mainly determined by retention time bloodstream, is one main limiting factors use PTT applications. For this reason, efficient targeting and monitoring se...
Patients with metastatic breast cancer have a five-year survival rate of 27% compared to 98% for localized cancer, and the presence of even a few cancer cells in lymph nodes, known as isolated tumor cells or nanometastases, significantly increases the risk of relapse in the absence of aggressive treatment. Therefore, diagnosis and treatment of lymphatic metastases in early breast cancer plays a...
HIV is a retrovirus which belongs to the family of lentiviruses. From the beginning of the HIV epidemic almost 75 million people have been infected and about 36 million people have died of HIV. Globally, 35.3 million people were living with HIV at the end of 2012. Gold nanoparticles (A. indica-GNPs) were synthesized from leaf extract of Azadirachta indica by microwave assistance. Surface chemis...
PURPOSE Gold nanoshells (NSs) have already shown great promise as photothermal actuators for cancer therapy. Integrin αvβ3 is a marker that is specifically and preferentially overexpressed on multiple tumor types and on angiogenic tumor neovasculature. Active targeting of NSs to integrin αvβ3 offers the potential to increase accumulation preferentially in tumors and thereby enhance therapy effi...
Colorectal cancer has high morbidity and mortality rate, with a level of metastasis recurrence due to the poor therapeutic effects. Photodynamic therapy (PDT) as an emerging clinical modality for treatment provides remarkable advantages over existing treatments by generating reactive oxygen species (ROS) through light irradiating photosensitizers (PSs) in presence oxygen. PDT can induce immunit...
Introduction Radiolabeled gold nanoparticles play an important role in biomedical application. The aim of this study was to prepare iodine-131 (131I)-labeled gold nanorods (GNRs) conjugated with cyclic RGD and evaluate its biological characteristics for targeted imaging of integrin αvβ3-expressing tumors. Methods HS-PEG(5000)-COOH molecules were applied to replace CTAB covering the surface of...
Objective. The objective of the present study is to synthesize and optimize bovine serum albumin nanoparticles coated with ofloxacin drug nano conjugate and evaluation of control release and anti bacterial activity against clinical isolate of Pseudomonas aeruginosa,Methods.Simple coacervation technique was implemented for preparation of BSA nanoparticles and optimization was carried out with va...
