Abstract:

Biomarkers, such as ions, small molecules, proteins, polysaccharides, nucleic acids, and cells, are involved in the building of organisms and play an important role in the life process. Accurate detection of these biomarkers is of great significance for disease research, early diagnosis, drug evaluation, and human health monitoring. The solid-state nanochannel is modified by functionalizing the outer surface of the nanochannel, which eliminates the restriction on the target molecule and greatly improves the speed and sensitivity of detection by means of a change based on the ion signal. This paper reviews the detection principle of solid-state nanochannels with modified outer surface in biomarkers, summarizes the research progress of solid-state nanochannels modified on outer surfaces in biomarker analysis, and briefly looks forward to the challenges and development opportunities of solid-state nanochannels modified on outer surfaces.

Key words: Nanochannels, Outer surface, Biomarkers
