We present a method to modify carbon-fiber microelectrodes (CFME) with porous carbon nanofibers (PCFs) to improve detection and to investigate the impact of porous geometry for dopamine detection with fast-scan cyclic voltammetry (FSCV). PCFs were fabricated by electrospinning, carbonizing, and pyrolyzing poly(acrylonitrile)--poly(methyl methacrylate) (PAN--PMMA) block copolymer nanofiber frameworks. Commonly, porous nanofibers are used for energy storage applications, but we present an application of these materials for biosensing which has not been previously studied.

Confined ionic liquids in hydrophilic porous media have disrupted lattices and can be divided into two layers: An immobile ion layer adheres to the pore surfaces, and an inner layer exhibits faster mobility than the bulk. In this work, we report the first study of ionic liquids confined in block copolymer-based porous carbon fibers (PCFs) synthesized from polyacrylonitrile--polymethyl methacrylate (PAN--PMMA). The PCFs contain a network of unimodal mesopores of 13.

- Researchers developed nanorods of a zirconium-based metal-organic framework (MOF), PCN-222, using a method that involved competing ligands to control crystal growth for use in reverse osmosis membranes.
- They modified the MOF by binding myristic acid to change its channel dimensions, which was characterized using gas sorption and NMR techniques.
- The modified MOF was incorporated into thin-film nanocomposite membranes, resulting in a significant increase in water flux (up to 95%) while still effectively rejecting salts, attributed to optimized water transport pathways.
