Marine Sponges a Good Source of Bioactive Compounds in Anticancer Agents”

摘要

Magnetic nanoparticles are a class of nanoparticle which can be manipulated using magnetic field. Such particles commonly consist of magnetic elements such as iron, nickel and cobalt and their chemical compounds. While nanoparticles are smaller than 1 micrometer in diameter (typically 5–500 nanometres), the larger micro beads are 0.5–500 micrometer in diameter. The magnetic nanoparticles have been the focus of much research recently because they possess attractive properties which could see potential use in catalysis including nanomaterial-based catalysts, biomedicine, magnetic resonance imaging, magnetic particle imaging, data storage, environmental remediation, nano fluids[ and optical filters. Nanoparticles play an increasing role in pharmaceutics and medicine. from physical and biological interest to applications in clinics. Magnetic Nanoparticles can be conjugated with any protein, drug and gene, and by that magnetic nano particles serve as contrast agent for MR imaging by changing the MRI signal. Additionally, they serve as a therapeutic tool by improving drug delivery to the target organ. This technology is of high interest for the pharmaceutical-industry. Magnetic nanoparticles enable in-vivo tracking of drugs, proteins and cells in many research fields, such as stem cell therapy, oncology, cordiovasculartherosclerosis, inflammation etc.
