Las nanoparticulas estan dispersas en agua? para medir su fluorescencia es necesario dispersarlas en otro disolvente?
1 answer-
This product is a 1% dispersion is water. The particles are composed of polystyrene, iron oxide, and fluoRed fluorescent dye. Diluting in other solvents is not necessary, water is a suitable diluent.
