| Abstract |
Novel ferrocenyl based carboranes (FcCBs) and their distinguish behavior for cancer cell recognition have been explored in this contribution. The voltammetric study in a droplet of 10μL placed on the surface of a glassy carbon electrode demonstrates the excellent electrochemical behavior of FcCBs, which could be further exploited for establishing the promising and sensitive biosensors. The FcCBs' redox behavior is examined in a wide pH range, and square wave voltammetry revealed the reversible and irreversible nature of first and second anodic peaks. The obvious shifts in peak potentials corresponding with the change of pH values demonstrate the abstraction of electrons to be accompanied with the transfer of protons. By using the droplet electrochemical technique, FcCBs can be employed to distinguish normal and cancer cells with a linear range from 1.0×10(3) to 3.0×10(4)cells mL(-1) and the limit of detection at 800cells mL(-1). The novel carborane derivatives could be utilized as important potential molecular probes for specific recognition of cancer cells like leukemia cells from normal cells.
