    摘要： A method and also a device is proposed for identification of a substance, preferably comprising biochemical molecules. In a first step a probe and said substance will be brought into contact, afterwards in a second step the probe and said substance will be withdrawn from each other, while measuring the value of at least one physical parameter characterizing the interaction between said probe and said substance and comparing said measured value with a reference value for identification.
    The physical parameter may include:

    applied forces directed on said substance (1) and said probe (p) during bringing into contact and withdrawing, and/or
    amount of displacement of said substance (1) and said probe (p) for bringing into contact and withdrawing and/or
    time duration between the beginning of withdrawing and complete separation of said substance (1) and said probe (p).
