a Water content of 0.5 wt% HA dissolved in increasing water:GFSH ratio over a period of one week. Red dotted line indicates the equilibrium water content attained at 60% RH. b Area under the force vs. displacement retraction curve (red stars) and maximum force measured during retraction (green squares) exhibiting recovery of sample adhesiveness for 0.5 wt% HA in GFSH upon cycling of relative humidity between 60% and 80%. Error bars represent standard deviation. Confocal microscopy of 0.5 wt% HA in GFSH when c freshly sprayed samples on day 0, d followed by spraying with water for 3 seconds, and e then sprayed with water for 10. Scale bars: 100 µm.
