c-myc mRNA has been established as a potential biomarker for detecting cancer, thanks to its critical function as a tumor suppressor or oncogene. Abnormal mRNA expression, in particular, is often seen during the development of early stage colon cancer. As a result, sensitive and specific detection of c-myc mRNA offers a potential way to make an early diagnosis of cancer, and has potential for the development of precision medicine.
Dr Themis Prodromakis, Reader in Nanoelectronics, University of Southampton, discusses how nanotechnology will play a major role in today’s contemporary life. The article has been published in The Conversation.
Researchers from Stanford University have developed a new technique that enables 3D imaging of tissues and cells under the skin in real time. This latest study has the potential to improve the diagnosis and treatment for blindness and certain forms of cancer.
From the tension of contracting muscle fibers to hydrodynamic stresses within flowing blood, molecules within our bodies are subject to a wide variety of mechanical forces that directly influence their form and function. By analyzing the responses of single molecules under conditions where they experience such forces we can develop a better understanding of many biological processes, and potentially, develop more accurately acting drugs. But up until now experimental analysis of single molecule interactions under force have been expensive, tedious and difficult to perform because it requires use of sophisticated equipment, such as an atomic force microscope or optical tweezers, which only permit analysis of one molecule at a time.
Researchers have developed a new technique for killing bacteria in seconds using highly porous gold nanodisks and light, according to a study published today in Optical Materials Express, a journal published by The Optical Society. The method could one day help hospitals treat some common infections without using antibiotics, which could help reduce the risk of spreading antibiotics resistance.
Researchers at the University of Cincinnati were excited when they realized that a new nanostructure, with higher properties for technological use, may allow doctors to observe and eliminate cancerous cells.
Researchers at the Houston Methodist Research Institute have developed a unique drug that effectively removes lung metastases in mice. This latest breakthrough may radically redefine the treatment of metastatic triple negative breast cancer.
Atherosclerosis is a disease that causes a buildup of plaque in arteries. The disease is an invisible and prolific killer, but its ability to hide in the body and create havoc may soon be lost. A new nanoparticle has been developed by scientists, that acts as if it were a high-density lipoprotein (HDL). The nanoparticle can light up as well as treat the plaques that clog the arteries. This therapy technique can potentially assist to prevent strokes and heart attacks.
Liposomes are an existing drug delivery vehicle, but they are detected by the immune system. Researchers from the universities of Basel and Fribourg have demonstrated that specially synthesized liposomes do not produce any reaction in human and porcine sera, as well as pigs.
Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.
