Stochastic sensing can detect analytes at the single-molecule level, in which a biological ion channel embedded in a lipid bilayer or a nano-scale sized pore fabricated in a solid-state membrane is used as the sensing element. By monitoring the ionic current modulations induced by the passage of the target analyte through the single pore, both the concentration and the identity of the analyte can be revealed. In this chapter, we highlight recent advances in the stochastic detection of terrorist agents and biomolecules, and in real-world sample analysis using alpha-hemolysin protein ion channels. |
