Researchers develop technique to concentrate, manipulate and separate a wide class of swimming bacteria

The technique is based on the transmission of tiny electric current in a very thin film sample cell containing a colony of bacteria. The current produces electrolysis that changes the local pH level in the vicinity of the electrodes.

Assessing exposure to airborne nanomaterials

New methods and tools for measuring exposure to airborne engineered nanomaterials will be required to protect the health of workers in nanotechnology-related jobs, estimated to total 10 million people by 2014, according to two occupational health experts writing in the inaugural issue of the journal Nanotoxicology.

Potential of nanotechnology in medicine

Scientists are working now to create novel nanostructures that serve as new kinds of drugs for treating cancer, Parkinson's and cardiovascular disease; to engineer nanomaterials for use as artificial tissues that would replace diseased kidneys and livers, and even repair nerve damage; and to integrate nanodevices with the nervous system to create implants that restore vision and hearing, and build new prosthetic limbs.

Improvement of cancer-targeting therapy, using nanocarriers for intractable solid tumors by inhibition of TGF-beta signaling

Administering a small amount of a potent but potentially toxic anticancer agent along with nanoparticles loaded with a second anticancer agent produced a dramatic inhibition of tumor growth in normally intractable cancers. These findings suggest a new approach to treating malignancies such as pancreatic cancer and diffuse gastric cancer.

Magnetic nanocrystals used to carry tumor-killing drugs

Imagine using a focused magnetic field to concentrate anticancer drugs in and around tumors, and then turning off the magnetic field so that the drugs then leave the body.

Targeted nanoparticles image early tumors

A well-established fact in cancer therapy is that early tumor detection improves the odds that a patient will survive the disease. Now, using nanoparticles targeted to the tiny blood vessels that surround even the smallest tumors, researchers at the Siteman Center for Cancer Nanotechnology Excellence (CCNE) have developed a radioactive imaging agent that was able to identify human tumors in rabbits.
