Neutron capture therapy using 157Gd (Gd-NCT) is currently under development as a cancer radiotherapy. Melanoma cells were treated with gadolinium-loaded chitosan nanoparticles (Gd-nanoCPs) for Gd-NCT. Smaller Gd-nanoCPs had higher Gd content and better cellular association of Gd and thereby made

The blood-brain barrier is a highly selective anatomical and functional interface allowing a unique environment for neuro-glia networks. Blood-brain barrier dysfunction is common in most brain disorders and is associated with disease course and delayed complications. However, the mechanisms underlying
