Considerable attention has been paid to the chemical and mechanical properties of perfluorosulphonic acid (PFSA) membranes on the horizon of polymers, particularly Nafion, because of their excellent material properties including chemical stability, permselectivity, and high-proton conductivity, enabling them to be ideal candidates for technological application in Proton exchange membrane fuel cell (PEMFCs) [1, 2].

Mice with claudin-2 or claudin-15 deficiencies in the small intestine reveal that these transmembrane proteins play essential roles in the transepithelial paracellular channel-like permselectivity for extracellular monovalent cations, especially Na(+), in both infants and adults [13].
Carbon membranes are usually prepared by the carbonization of polymer precursors, which provide better permselectivity, thermal and mechanical stability, and chemical stability compared to the commercial polymeric membranes already used [2-5].
However, mild proteinuria in patients with Alport syndrome indicates a minor role of this collagen in permselectivity of proteins.
Because the normal formation of podocyte slit diaphragms is the integral part of the glomerular permselectivity, its dysregulation constitutes a major cause of pathological proteinuria [26].
ELASTISLET relies on the most innovative ideas taken from synthetic biology, nanobiotechnology and molecular and cellular biology to build the ideal niche for islet/cell encapsulation and transplantation.ELASTISLET main objective is to achieve a functional coating that fulfils, first, the basic requirements of optimal biocompatibility and physical properties (permselectivity) but, second, generate a capsule that can promote an intense and directed cross talk through all cell-material interfaces involved: the implant-surrounding tissue (outer) interface and cargo cells-capsule (inner) interface.

In contrast, conducting polymers (CPs) function as redox mediators for electron and proton between the electrodes and the electroactive reactants shows permselectivity towards some species; they permit the diffusion of redox active species (e.g., methanol) to the active sites of electrode and enhance the electrooxidation current [11, 12].
