摘要：
A method of detecting exocytosis of a target molecule from a population of cells derived from a human subject, includes applying first and second electrical signals, each having a respective frequency, across the population of cells. Each of the first and second electrical signals being either an alternating current or an alternating voltage. The method includes measuring a first voltage change if the first electrical signal is an alternating current or measuring a first current change if the first electrical signal is an alternating voltage, and measuring a second voltage change if the second electrical signal is an alternating current or measuring a second current change if the second electrical signal is an alternating voltage. The method includes determining an electrical impedance of the population of cells, a change in that impedance indicating an amount of the target molecule released from the population of cells.
