Evaporation of the droplets as a function of time. (a) 25 mM NaH2PO4, 215 mM NaCl buffer. Dark blue: acquisition time 30 s, delay between exposure 30 s (30/30). Light blue: 10/50. (b) rHSA in buffer (a) droplet with a start concentration of 20 mg ml−1. Red: 30/30; yellow: 10/50 [data acquisition time/break (s)]. |
