Miniaturizable ion-selective arrays based on highly stable polymer membranes for biomedical applications [PDF]

, 2015
Poly(vinylchloride) (PVC) is the most common polymer matrix used in the fabrication of ion-selective electrodes (ISEs). However, the surfaces of PVC-based sensors have been reported to show membrane instability. In an attempt to overcome this limitation,
