基于封闭效应的自供电逻辑生物传感器。
Closed effect on self-powered logic biosensors.
基于封闭效应发展的自供电逻辑生物传感器,往往在BFC两极修饰适配子或脱氧核酶等具有识别能力的生物大分子,在多种目标物处于某种存在状态时,它们在电极表面可自由伸展,不阻碍电极表面的电子传递;一旦目标物达到特定的存在状态时,适配子或脱氧核酶与相应的目标物结合,形成复合物,吸附于电极表面,从而使两极电子传递受到不同程度的抑制,表现出BFC各电参数的变化。
Self-powered logic-based biosensor closed effects of development, often in the BFC bipolar modified aptamer or Deoxyribozyme so has the ability to identify biological macromolecules, in the presence of multiple targets in a certain state, they are free to the electrode surface stretching, the surface of the electron transfer is not hindered; Once the object reaches a certain state of presence, an aptamer, or DNAzyme with a corresponding object, forming a complex adsorbed on the electrode surface, so that the electron transfer be different poles the degree of inhibition of the changes in the performance of the electrochemical parameters BFC.
这种逻辑传感器以几种目标物的存在状态(如无目标物存在、单一目标物存在、目标物均存在等)为输入信号Input,以电池的电参数达到某一定值作为输出信号Output,基于电极表面的封闭效应来设计逻辑关系,从而构建不同逻辑关系的自供电传感器。
The logic state of the sensor in the presence of several target object (such as no target object is present, the presence of a single target, the target material are present, etc.) to the input signal Input, the electrochemical parameters of the battery reaches a certain value as an output signal Output, closed effect on the electrode surface to design a logical relationship, in order to build a self-powered sensors based on different logical relationships.
