Our current understanding of how the brain works is very poor. The electrical signals travel around the brain and throughout the body, and the electrical properties of the biological tissues are studied using electrophysiology. For acquiring a large amplitude and a high quality of neuronal signals, intracellular recording is a powerful methodology compared to extracellular recording to measure the voltage or current across the cell membranes.
A new and highly efficient technique has been developed for gene transfer by a group of researchers from the University of Rochester Medical Center (URMC) and the Rochester Institute of Technology (RIT).
EPFL researchers have shown that a law of physics having to do with electron transport at nanoscale can also be analogously applied to the ion transport. This discovery provides insight into a key aspect of how ion channels function within our living cells.
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.
