Abstract: Various examples are provided related to electrochemical phosphate/pH (P/pH) sensors, systems and related methods. In one example, a P/pH sensor includes a substrate and collocated phosphate (P) electrode and pH electrode formed on a surface of the substrate. The P electrode includes a cobalt (Co) sensing window disposed on a first copper (Cu) sensor pad; and the pH electrode includes an antimony (Sb) sensing window disposed on a second Cu sensor pad. The P/pH sensor can include a reference electrode, and may also include other sensor electrodes such as, e.g., a nitrate electrode.

Abstract: Various examples of methods and systems related to nanofibrous microstructures including carbon nanofibrous microelectrode arrays are provided. In one example, a method includes electrospinning photosensitive nanofibers on a patterned substrate; immersing the photosensitive nanofibers in a refractive index matching medium; and exposing the immersed photosensitive nanofibers to ultraviolet (UV) light through the patterned substrate or through a front side photomask. In another example, a microelectrode array includes a carbon thin film (CTF) trace pattern including a plurality of CTF electrode pads; and a plurality of carbon nanofiber (CNF) pillars disposed on the plurality of CTF electrode pads.
