Gene therapy: utilizing nanotechnology in fighting against Chlamydia

Scientists in Canada have developed a new method for preventing and treating chlamydia. Chlamydia, caused by Chlamydia trachomatis, is a common sexually transmitted disease that can infect women with cervicitis and in both men and women with urethritis and proctitis. The team of researchers from the University of Waterloo treats chlamydia through gene therapy using nanotechnology.

NSF awards Indiana University $4 million to advance medical nanotechnology

Only a year after establishing the intelligent systems engineering program in the Indiana University School of Informatics, Computing and Engineering, the university has been awarded a five-year, $4 million grant from the National Science Foundation to advance nanoscale devices to improve human health, including fighting cancer.

Self-assembling nanomaterial offers pathway to more efficient, affordable harnessing of solar power

New nanomaterials developed by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York (CUNY) could provide a pathway to more efficient and potentially affordable harvesting of solar energy. Early research suggests these materials could create more usable charges and increase the theoretical efficiency of solar cells up to 44 percent.

New immune system understanding may lead to safer nanomedicines

Doctors would like to use all sorts of nanoparticles in the body, for example to construct detailed images of anatomy and disease, and to deliver cancer-fighting drugs deep within tumor tissue. However, millions of years of evolution have equipped the body to identify and reject foreign particles, even nanoparticles. And so one major challenge in the use of nanomedicine has been the immune system's unfortunate efficiency in responding to what it sees as infection, at best clearing nanoparticles before they can accomplish their goals, and at worst, leading to dangerous immune overreaction that creates side effects and serious risks.

Targeting headaches and tumors with nano-submarines

New method of transporting drugs published in Nature Nanotechnology Scientists at the Mainz University Medical Center and the Max Planck Institute for Polymer Research (MPI-P) have developed a new method to enable miniature drug-filled nanocarriers to dock on to immune cells, which in turn attack tumors.
