Abstract
In this paper, a biocompatible biosensor based on horizontal Si nanowire (NW) array field-effect transistor (FET) has been fabricated by the feasible spacer image transfer (SIT) process. The Si NW FET as biosensor is proposed for the realtime cellular Ca2+ monitoring for mesenchymal stem cells (MSCs), which presents fast-responded and high-sensitive characteristics. Compared with the conventional sensing techniques, the Si NW biosensor exhibits non-invasive, biocompatible and reliable advantages. This will help us to further understand the mechanism of cellular ion activities and provides a promising method for the cell-level diagnose and therapy.
