Researchers clear hurdle on path toward gene-therapy treatment for disease

One of the most difficult aspects of working at the nanoscale is actually seeing the object being worked on. Biological structures like viruses, which are smaller than the wavelength of light, are invisible to standard optical microscopes and difficult to capture in their native form with other imaging techniques.

New nanomaterial could improve therapeutics and imaging in cancer treatment

Scientists from UCLA’s California NanoSystems Institute and Korea’s Yonsei University have developed an innovative method that enables nanomachines to release drugs inside living cancer cells when activated remotely by an oscillating magnetic field.

Tel Aviv University researcher develops nano-methods for treating cancer tumors with heat and magnets

Though a valuable weapon against cancerous tumors, radiation therapy often harms healthy tissue as it tries to kill malignant cells. Now, Prof. Israel Gannot of Tel Aviv University’s Department of Biomedical Engineering is developing a new way to destroy tumors with fewer side effects and minimal damage to surrounding tissue.

Novel bee venom derivative forms a nanoparticle ’smart bomb’ to target cancer cells

August 1, 2010 by admin · Leave a Comment 

New research in the FASEB Journal shows that a peptide derived from bee venom can deliver liposomes bearing drugs or diagnostic dyes to specific cells or tissues

The next time you are stung by a bee, here’s some consolation: a toxic protein in bee venom, when altered, significantly improves the effectiveness liposome-encapsulated drugs or dyes, such as those already used to treat or diagnose cancer. This research, described in the August 2010 print issue of the FASEB Journal (http://www.fasebj.org), shows how modified melittin may revolutionize treatments for cancer and perhaps other conditions, such as arthritis, cardiovascular disease, and serious infections.

New technology targets cancer prevalent in young women

CHICAGO — You can teach an old drug new chemotherapy tricks. Northwestern University researchers took a drug therapy proven for blood cancers but ineffective against solid tumors, packaged it with nanotechnology and got it to combat an aggressive type of breast cancer prevalent in young women, particularly young African-American women.

Evidence that nanoparticles in sunscreens could be toxic if accidentally eaten

June 22, 2010 by admin · Leave a Comment 

Scientists are reporting that particle size affects the toxicity of zinc oxide, a material widely used in sunscreens. Particles smaller than 100 nanometers are slightly more toxic to colon cells than conventional zinc oxide. Solid zinc oxide was more toxic than equivalent amounts of soluble zinc, and direct particle to cell contact was required to cause cell death. Their study is in ACS’ Chemical Research in Toxicology, a monthly journal.

Scientists are reporting development and successful testing of a sensor that can instantly tell whether someone has Type I diabetes. It could also be used by emergency room doctors to determine whether a patient has developed diabetic ketoacidosis, a potentially serious complication that happens when diabetics do not take enough insulin. Someday the technology may also be used by diabetics, in their own homes, to determine whether they need more insulin. A report on the sensor appears in ACS’ Analytical Chemistry, a semi-monthly journal.

A $145-million Federal Government effort to harness the power of nanotechnology to improve the diagnosis, treatment, and prevention of cancer is producing innovations that will radically improve care for the disease. That’s the conclusion of an update on the status of the program, called the National Cancer Institute Alliance for Nanotechnology in Cancer. It appears in ACS Nano, a monthly journal published by the American Chemical Society.
