CNT Densely aligned Carbon Nanotubes-based Biosensor for accurate sensing of Biomolecules and Use thereof

摘要

The present invention relates to a method for manufacturing a high-density aligned CNT-based biosensor for highly sensitive detection of biomolecules, a biosensor manufactured by the method, and uses thereof. Through the biosensor manufacturing method of the present invention, it is possible to manufacture a biosensor having the highest performance reported currently capable of detecting a target molecule present at a femtomolar level without cross-reactivity to a non-target molecule. In particular, it can accurately detect biomarkers present at a level of several femtomoles in a patient's sample, and it is accurate at low cost, out of the existing invasive or uneconomical time/monetary biomarker detection and diagnosis methods for neurodegenerative diseases. Detection and diagnosis of high biomarkers are possible. The biosensor manufacturing method and biosensor of the present invention are not only for neurodegenerative diseases, but also for diagnosis, prognosis, and probability prediction in various medical fields through high-accuracy detection of biomarkers that were difficult to detect due to low concentrations and presence of interfering substances. It can be usefully used, and in addition to medical purposes, it can be usefully used in various fields such as environment, food, military, industry, and research through detection of target molecules.
