    Radioactive Nanoparticles Developed That Target Cancer Cells

    Cancers of all types become most deadly when they metastasize and spread tumors throughout the body. Once cancer has reached this stage, it becomes very difficult for doctors to locate and treat the numerous tumors that can develop. Now, researchers at the University of Missouri have found a way...

    Nanoparticles Stop Multiple Sclerosis In Mice

    A breakthrough new experimental treatment that uses nanoparticles covered with proteins to trick the immune system, managed to stop it attacking myelin and halt disease progression in mice with relapsing remitting multiple sclerosis (MS). The researchers say the approach may also be applicable...

    Nanoparticles Can Hinder Intracellular Transport

    Scientists at the Centre of Cancer Biomedicine at the Norwegian Radium Hospital are the first to show that uptake and accumulation of nanoparticles in cells can disrupt important intracellular transport pathways. The researchers discovered that the nanoparticles interrupt the transport of vital...

    Resistant Cancers 'Opened Up' Curcumin Nanoparticles

    Pre-treatment with curcumin, a component of the spice turmeric, makes ovarian cancer cells more vulnerable to chemotherapy and radiotherapy. Researchers writing in BioMed Central's open access Journal of Ovarian Research found that delivering the curcumin via very small (less than 100nm)...

    Hitting Cancer Where It Hurts Using Gold Nanoparticles

    Taking gold nanoparticles to the cancer cell and hitting them with a laser has been shown to be a promising tool in fighting cancer, but what about cancers that occur in places where a laser light can't reach? Scientists at the Georgia Institute of Technology have shown that by directing gold...
