Detecting lung cancer early with sugar-sensing nanotech
Jul 01, 2024 (Nanowerk News) For such a common disease, lung cancer can be hard to spot. In the early stages you probably won’t even know you’ve got a problem. But by the time you investigate that persistent cough, your livelihood may already hinge on a range of expensive, invasive...
Can a computer chip have zero energy loss in 1.58 dimensions?
Jul 01, 2024 (Nanowerk News) What if we could find a way to make electric currents flow, without energy loss? A promising approach for this involves using materials known as topological insulators. They are known to exist in one (wire), two (sheet) and three (cube) dimensions; all with different possible...
A combination of magnetic nanoparticles and chemotherapy drugs achieves greater efficacy against cancer cells
Jul 01, 2024 (Nanowerk News) The path to a cure for cancer is not unique, as the disease is an extremely complex process. Multiple factors are involved in the process of effectively eliminating a tumour and therefore, being able to have different strategies against cancer is key in this regard....
