A probe unit for identifying a target nucleotide region in a target nucleic acid, the unit being provided with an electrode, a probe bound to the electrode and recognizes the target nucleic acid, and a hole-transfer-inducing agent bound to the probe, wherein a nucleotide region corresponding to the target nucleotide region is located between the hole-transfer-inducing-agent-binding site and the electrode-binding end of the probe. A state of the target nucleotide region in the target nucleic acid can be identified by comparing electrochemical signal levels by energy-induced hole transfers before and after the hybridization of such a probe unit with the target nucleic acid.
一种用于识别目标核酸中的目标核苷酸区域的探针单元,该单元具有电极、与电极结合并识别目标核酸的探针和结合于探针上的孔传输诱导剂,其中与目标核苷酸区域相对应的核苷酸区域位于孔传输诱导剂结合位点和探针的电极结合端之间。通过比较探针单元与目标核酸杂交前后通过能量诱导的孔传输产生的电
