Extended Data Fig. 3: SEBS organogel encapsulation enabled preservation of droplet networks in physiological environments.
From: A microscale soft ionic power source modulates neuronal network activity
a, Schematic showing the SEBS organogel encapsulation. b, Photographs of a droplet power source formed from 500 nL droplets and encapsulated in an organogel cube. Comparison with a one-penny coin (20.3 mm diameter). c, The encapsulated droplet power source is soft and can withstand repeated bending and twisting by hand. d, The open-circuit voltages are shown for droplet power sources encapsulated in organogel after 30 min immersion in phosphate buffered saline (pH 7.4, Gibco) or rabbit blood (New Zealand white rabbit strain, Envigo).
