Özet
In this study, Citropin-A (Cit-A) as a biorecognition receptor was used for the first time to develop electrochemical impedance spectroscopy (EIS) based biosensor for the detection of Lymph Node Carcinoma of the Prostate (LNCaP) cancer cells. The biosensor was engineered by modification of a gold electrode (AuE) with cysteamine (Cys), Poliamidoamin (PAMAM (G4)) dendrimers, avidin, and biotinylated Cit-A, respectively. The detection time of the LNCaP cells was determined as 300 s by chronoimpedance (CI). Chronoimpedance also provided an exact detection time to avoid non-specific adsorptions. The biosensor showed good linearity between 1500 cells/L and 12000 cells/L, limit of detection (LOD), and limit of quantification (LOQ) values were 518 cells/L and 1570 cells/L, respectively.
