nanoparticles promising future cancer therapy

4 March, 2019 – 4:32 am |

Abstract Recently, the use of gold nanoparticles as potential selective tumor radiosensitizer has been proposed as a major advance in radiotherapy. Experiments in living cells and in vivo have demonstrated the effectiveness of metal nanoparticles when combined with low energy X-ray radiation (below 1 MeV Linac conventional radiation). Other DNA studies have performed in order […]

Nano particles to kill Cancer

3 March, 2019 – 4:32 am |

Using lasers and nanoparticles, scientists at Rice University have discovered a new technique to single person and destruction of diseased cells with small explosions. The scientists used a laser to create “nanoburbujas” zapping gold nanoparticles inside cells. In tests on cancer cells, they found they could adjust the laser to create or small, glowing bubbles […]

Titanium Dioxide Nanoparticles Catalyze Brain Tumor Death

28 November, 2018 – 4:32 am |

U.S. scientists Department of Energy (DOE) Argonne National Laboratory and the University of Chicago Medical Center’s Brain Tumor Center have developed a way to target cancer cells of the brain using inorganic titanium dioxide nanoparticles bonded to antibodies. Thousands of people die from malignant brain tumors each year, and the tumors are resistant to conventional […]

Magnetic Nanoworms and Nanocrystals Deliver siRNA to Tumors

3 November, 2018 – 4:32 pm |

Small pieces of nucleic acid known as short interfering RNA, or siRNA, can disable the production of specific proteins, a property that makes them one of the most promising new classes of anticancer drugs in development. In fact, at least two siRNA-based therapies against cancer, both delivered to tumors in nanoparticles, have begun human clinical […]

Therapeutic nanoparticles give new meaning to sugar-coating medicine

27 October, 2018 – 4:32 am |

A research team at the National Institute of Standards and Technology to study sugar-coated nanoparticles for use as cancer therapy has discovered a possible delicate balancing act that makes the particles more effectively than conventional thinking says they should be. Like the individuals in the crowd while respecting the personal space of others work because […]

New discovery reveals fate of nanoparticles in human cells

12 October, 2018 – 4:32 am |

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered what happens to nanoparticles when they enter biomimetic human cells. They found that the important proteins that form the outer layer of the nanoparticles are degraded by an enzyme called cathepsin L. Scientists now have to take into account this phenomenon and […]

World’s first nanofluidic device with complex 3-D surfaces

30 April, 2018 – 4:32 am |

Analysts at the Commerce Department’s State Institute of Standards and Technology and Cornell School have capitalized on a method for manufacturing integrated circuits at the nanometer level and used it to develop a strategy for engineering the very first nanoscale fluidic device with complicated three-dimensional surfaces. As explained in a paper published online today in […]
