Abstract The mesenchymal state in cancer is usually associated with poor prognosis due to the metastatic predisposition and hyper-activated metabolism. Exploiting cell glucose metabolism we propose a new method detect mesenchymal-like cells. We demonstrate that uptake of glucose-coated magnetic nanoparticles (MNPs) by cells remains constant when medium increased from low (5.5 mM) high (25 concentration, while MNPs epithelial-like significantly reduced. These findings reveal glucose-shell...
