摘要：
The present disclosure relates, according to some embodiments, to methods, devices, and systems for fluid delivery to a subject using pumps, for example, non-gassing, direct current (DC), electro-osmotic pumps. In some embodiments, delivery of an aqueous fluid may be achieved by contacting the aqueous liquid with an electro-osmotic pump comprising (i) a cathode (e.g., a cathode comprising porous carbon coated with a cerium oxide-comprising coating), (ii) an anode (e.g., an anode comprising porous carbon coated with a cerium oxide-comprising coating), and (iii) a ceramic membrane (e.g., a ceramic membrane formed by fusing uncoated silica spheres, phosphosilicic-acid-coated fused silica spheres, or borosilicic-acid-coated fused silica spheres, wherein the fused spheres are randomly packed between the cathode and the anode) and/or optionally applying (a) a constant potential difference or constant voltage between the anode and the cathode of from about 0.1 V to about 3 V between the anode and the cathode of from about 0.1 V to about 3 V such that the aqueous liquid is pumped or (b) constant current to cause a potential difference between the anode and the cathode of from about 0.1 V to about 3 V such that the aqueous liquid is pumped.
