Portable test kits represent an advance in disease diagnosis, as their
ready availability increases chances of earlier detection and treatment.
This type of technology is constantly evolving, and sometimes
inspiration can come from surprising sources. Such is the case with
research carried out by a Swiss team, which has borrowed from the
mechanics behind the firefly's glow to develop a sensitive molecule
When things in our body go awry, through disease or infection, for example, the types of molecules in our breath can change. These variations have presented researchers around the world with a very real opportunity to detect various conditions, including lung cancer, with unprecedented ease. The latest scientists to start sniffing around this emerging form of medical diagnosis is a team from the University of Adelaide, who are developing a laser instrument inspired by dog's nose that can screen breath samples for signs of unrest.
Today's smartphones come chock-full of technological capability, intended to help us with everything from taking holiday snaps, finding our way around a new town or staying connected with people around the world. As it turns out, the hardware inside is starting to show huge promise in the world of medical diagnostics, with smartphones repurposed as blood-scanning microscopes, HIV testers and sleep apnea detectors. The latest advance in this area comes in the form of a fiber optic sensor for smartphones that monitors bodily fluids, a tool that could be used for biomolecular tests such as pregnancy or diabetes monitoring.
Researchers at the Universidad Carlos III de Madrid (UC3M) and the
Institute Ramón y Cajal for Health Research (IRYCIS) have created a new
device that significantly cuts down the time required to perform a skin
biopsy. It doesn't require any specialized skills to use, and could open
the door to faster skin cancer diagnoses.
