(Phys.org) —A combined team of researchers from Portugal and Spain has found that it might be possible to use nanographene oxide to help improve the tumor killing capability of chemo, radiotherapy or laser treatments in ...
Biomolecular 'nanocarriers' formed by the careful assembly of protein subunits are common in nature and perform a range of essential roles in biological processes, powered by the biological energy carrier adenosine-5'-triphosphate ...
