Linear dose dependency of MSC detection employing ICP-MS. NMSC = 0–100,000 MSCs labeled with cNP = 10 nM of Au NPs for 48 h were mixed with NHL = 106 unlabeled HL-60 cells. Then, the number NMSC,detect of MSCs in the mixture was determined via ICP-MS. The dashed line represents the expected results under optimal conditions. The Au noise background level and therefore the detection limit was corresponding to NMSC,limit ~ 400 labeled cells
