Abstract: Nystatin is a polyene antifurgal drug to which many molds and yeasts are sersitive, including cryptococcus neoformans, candida, aspergillus, etc. To realize the mechanism of nystatin more particularly, the techniques of SPR and impedance were used to investigate the interaction between nystatin and two kinds of solid-supported phospholipid membranes. The results show that nystatin could interact with pure phospholipid membranes, whether they are monolayer or bilayer. In addition, impedance spectra show that ion channels may be formed when nystatin interacted with phospholipid membranes.

Key words: Surface plasmon resonance, A.C. impedance, Solid-supported phospholipid membrane, Nystatin
