Nanomedicine aims to develop smart approaches for treating cancer and other diseases improve patient survival quality of life. Novel nanoparticles as nanodiamonds (NDs) represent promising candidates overcome current limitations. In this study, NDs were functionalized with a 200 kDa hyaluronic acid-phospholipid conjugate (HA/DMPE), enhancing the stability in water-based solutions selectivity cells overexpressing specific HA cluster determinant 44 (CD44) receptors. These characterized by diffuse reflectance Fourier-transform infrared spectroscopy, Raman photoluminescence confirming efficacy functionalization process. Scanning electron microscopy was employed evaluate size distribution dry particles, while dynamic light scattering zeta potential measurements utilized ND behavior medium. Furthermore, biocompatibility uptake mediated CD44 receptors three different models human adenocarcinoma assessed performing cytofluorimetric assay confocal microscopy. HA-functionalized demonstrated advantage active targeting presence expressing on surface, suggesting higher drug delivery tumors over non-tumor tissues. Even CD44-poorly cancers could be targeted NDs, thanks their good passive diffusion within cells.

Cell migration is a crucial parameter for disease progression in cancer. Reactive oxygen species (ROS) levels are involved the regulation of process, however, exact role free radical generation and where it occurs unknown. Here we use diamond-based quantum sensing technique to detect radicals during cancer cell real time with subcellular resolution. We investigated metastatic MDA-MB-231 human breast cells observed formation after 16 h starvation 24 under low-serum conditions. Intracellular diamond dynamics were monitored at different points (0, 12, h), morphology was evaluated. Additionally, number focal adhesions analyzed as an indicator migratory potential cells. further measured nicotinamide adenine dinucleotide phosphate hydrogen NADPH oxidases 2 (NOX2) inhibition by apocynin. found that decreased treatment 36 μg/mL apocynin while ROS capacity increased. Our results evidence complexity redox migrating offer novel approach specifically locally interrogate pivotal players oxidative network behind success.
