Nanotags pinpoint multiple cancer markers in live animals

Using nanoparticles designed specifically to produce a bright Raman spectroscopic signal, a team of investigators at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (Stanford University Center for Cancer Nanotechnology Excellence [CCNE]) has shown that it can simultaneously track as many as 10 different optical tags in a living animal.

Aptamer nanoflares for molecular detection in living cells

By combining a gold nanoparticle with a unique family of nucleic acids, researchers at Northwestern University have created a new type of intracellular reporting system that with a flash of light reveals the presence and quantity of a wide variety of biologically important molecules. These so-called nanoflares could provide cancer biologists with a highly sensitive method of tracking complex biochemical processes in real time without interfering with those processes.

Nanotubes destroy kidney tumors

By injecting multiwalled carbon nanotubes (MWCNTs) into tumors and heating them with a quick, 30-second zap of a laser, a multi-institutional team of researchers from the Wake Forest University School of Medicine (WFUSOM), Wake Forest University Center for Nanotechnology and Molecular Materials, Rice University, and Virginia Polytechnic Institute and State University has developed a new type of therapy that effectively kills kidney tumors in nearly 80% of treated mice. Researchers say that the findings, which were published in the Proceedings of the National Academy of Sciences of the United States of America, suggest a potential future cancer treatment for humans.

Nanoparticle-delivered suicide gene therapy effectively reduces ovarian tumor burden in mice

Nanoparticle delivery of diphtheria toxin-encoding DNA that expresses selectively in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect that this therapy could be tested in humans with advanced ovarian cancer within 18 to 24 months, according to a report in Cancer Research. If additional tests are successful, these finding could lead to a new treatment for ovarian cancer, which now causes more than 15,000 deaths each year in the United States. Because it is usually diagnosed at a relatively late stage, ovarian cancer is one of the most deadly forms of the disease.

Rapid detection and profiling of cancer cells in fine-needle aspirates

Using a new type of paramagnetic nanoparticle and a nuclear magnetic resonance (NMR) system built into a microfluidic device, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has created an assay system capable of detecting as few as two cancer cells in 1 microliter of biological fluid. In addition, the new assay requires little sample processing and produces results in less than 15 minutes.

Reversible cell-specific drug delivery with aptamer-functionalized liposomes

For cancer drug developers, finding an agent that kills tumor cells is only part of the equation. The drug also must spare healthy cells, and ideally its effects will be reversible to cut short any potentially dangerous side effects. Investigators from the University of Illinois at Urbana-Champaign report that they have assembled a new cancer drug delivery system that, in cell culture, achieves all of the above.

Molecularly targeted nanocarriers deliver the cytolytic peptide melittin specifically to tumor cells in mice, reducing tumor growth

When bees sting, they pump into their victims a peptide toxin called melittin that destroys cell membranes. Now, by encapsulating this extremely potent molecule within a nanoparticle, researchers at the Washington University School of Medicine in St. Louis have created a potential new type of anticancer therapy with the potential to target a wide range of tumors. This work was reported in the Journal of Clinical Investigation.

ASNM inaugral conference to discuss the latest in nanomedicine

Nanomedicine - the science and technology of diagnosing, treating and preventing disease to improve human health using nanotechnology - has the potential to revolutionize healthcare. Current and future products range from miniaturized "smart pills" that precision-target certain cancers to nanosensors that are capable of navigating through the body for early detection of disorders.

NSF grants funds to develop next-generation nano-CT imaging system

In 1991, Ge Wang produced the first paper on spiral cone-beam computed tomography (CT), now an imaging technique used in the mainstream of the medical CT field. Today, Wang, known as a pioneer in this field, and his colleagues have been awarded more than $1.3 million from the National Science Foundation (NSF) to develop the next-generation nano-CT imaging system, which promises to greatly reduce the required dose of radiation.
