Scientists discover simple method to measure density of engineered nanoparticles in physiological fluids

Thousands of consumer products containing engineered nanoparticles — microscopic particles found in everyday items from cosmetics and clothing to building materials — enter the market every year. Concerns about possible environmental health and safety issues of these nano-enabled products continue to grow with scientists struggling to come up with fast, cheap, and easy-to-use cellular screening systems to determine possible hazards of vast libraries of engineered nanomaterials.

A fast, non-invasive method to genotype late-onset Alzheimer's disease

A fast, non-invasive method to genotype late-onset Alzheimer's disease

The apolipoprotein E gene ε4 allele is considered a negative factor for neural regeneration in late-onset Alzheimer's disease cases. [More]

Researchers exploit plasmonic nanoparticles to kill tumour cells

If you put your hand over a switched-on torch in the dark, it appears to glow red. This is because long-wavelength red light beams penetrate human tissue more effectively than short-wavelength blue light. [More]

Self-assembling DNA cages hold potential promise in drug delivery

Move over, nanotechnologists, and make room for the biggest of the small. Scientists at the Harvard's Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium. [More]
Researchers find effective strategy to eliminate cancer stem-like cells

Researchers find effective strategy to eliminate cancer stem-like cells

Combining nanodrug-based chemotherapy and cryoablation provides an effective strategy to eliminate cancer stem-like cells (CSCs) the root of cancer resistance and metastasis, which will help to improve the safety and efficacy of treating malignancies that are refractory to conventional therapies.

Researchers find ways to selectively pinpoint and target cancer cells

Researchers find ways to selectively pinpoint and target cancer cells

In current research related to improving cancer treatments, one promising area of research is the effort to find ways to selectively pinpoint and target cancer cells while minimizing effects on healthy cells. [More]
Local hyperthermia treatment induces mechanism of anti-tumor immune resistance

Local hyperthermia treatment induces mechanism of anti-tumor immune resistance

A combination of iron-oxide nanoparticles and an alternating magnetic field, which together generate heat, have activated an immune system response to tumors in mice according to an accepted manuscript by Dartmouth-Hitchcock Norris Cotton Center researchers in the journal Nanomedicine: Nanotechnology, Biology and Medicine released online on February 24, 2014.

Researchers find new technique to detect just a handful of lurking tumor cells

Beating cancer is all about early detection, and new research from the University of South Carolina is another step forward in catching the disease early. A team of chemists is reporting a new way to detect just a handful of lurking tumor cells, which can be outnumbered a billion to one in the bloodstream by healthy cells. [More]
Silver nanoparticles in dietary supplements, cosmetics and food packaging can cause damage to cells

Silver nanoparticles in dietary supplements, cosmetics and food packaging can cause damage to cells

Endocrine disrupters are not the only worrying chemicals that ordinary consumers are exposed to in everyday life. Also nanoparticles of silver, found in e.g. dietary supplements, cosmetics and food packaging, now worry scientists. [More]

Researchers create new probe that freezes cells to "see" at greater detail without damaging

It's an odd twist. For scientists to determine if a cell is functioning properly, they must destroy it. This is what happens in X-ray fluorescence microscopy when biological specimens are exposed to ionizing radiation, which provides images with a level of detail that conventional microscopes just can't match.

Engineers develop paper test that could improve diagnosis rates for cancer

Cancer rates in developing nations have climbed sharply in recent years, and now account for 70 percent of cancer mortality worldwide. Early detection has been proven to improve outcomes, but screening approaches such as mammograms and colonoscopy, used in the developed world, are too costly to be implemented in settings with little medical infrastructure.
