A New Way To Detect Cancer Early

A New Way To Detect Cancer Early 

 

A prototype device employs the same magnetic phenomenon used to write data to computer hard drives.

A new system for detecting cancer proteins uses the same magnetic phenomenon that lets computer hard drives read and write data. The Stanford University researchers developing the system hope that it will detect cancer in its earlier stages, when it’s easier to treat. MagArray, a startup in Sunnyvale, CA, will commercialize the technology.

Ten Minute Blood Test To Identify Cancer Proteins

Ten Minute Blood Test To Identify Cancer Proteins 

 A microfluidic chip identifies 35 proteins in a drop of blood within 10 minutes.

Measuring proteins in the blood can help doctors determine patients’ cancer risk and monitor the health of the elderly and people with chronic diseases. But current methods for testing these proteins are too expensive and require too much blood to be performed regularly. A microfluidic chip in clinical trials does on a single chip in 10 minutes what normally takes multiple technicians hours to do–and with just a single drop of blood. Researchers hope to make bedside diagnostics based on blood proteins a reality by bringing down the cost of such tests by at least an order of magnitude.

MicroRNA In Blood May Help Detect Cancer And Other Diseases

MicroRNA In Blood May Help Detect Cancer And Other Diseases 

 

Tiny pieces of RNA are turning out to play a big role in health. Over the past few years, scientists have found that these molecules, called microRNAs, are involved in key functions in cells and are linked to the development of certain cancers and other diseases. A new study led by scientists at Nanjing University, in China, finds that microRNAs circulating in blood can serve as a molecular “fingerprint” for cancers and diabetes. The findings raise the possibility that a simple blood test could help clinicians tailor treatments to individual patients.
