The invention relates to a preparation method for a carbon nanofiber electrochemistry biology sensor, which is as follows: firstly, processing carbon nanofiber CNF and than preparing CNF and an enzyme modified electrode. In the condition of the presence of NAD<+>, the ADH fixed in the modified electrode can catalyze alcohol and simultaneously NAD<+> is reduced to NADH. As CNF has very good electrochemistry oxidation performance on the NADH, NADH generated by detection is used for indirectly detecting alcohol content in the sample. Hereby, a field rapid detection analyzer for human body blood alcohol content is manufactured and used for instantly and rapidly testing the blood alcohol content of a driver on traveling crane field, thus instantly and rapidly judging whether the driver drinks on the field, thus effectively preventing a drinker from driving a car and avoiding the occurrence of traffic accidents.
