Purification: A centrifuge amenable to automation featuring a precise positioning of the rotor and temperature control, RobotCen (Herolab) with an AF 8.50.3 rotor with a maximum capacity of 8×50 mL, is utilized. For subsequent sonication and particle redispersion, a probe sonicator UP200St (Hielscher, 200W, 26kHz) and a bath sonicator Sonorex Digitec DT 255 H-RC (Bandelin) are used.
