Abstract:

The biological nanopore technique is a revolutionary single-molecule electrochemical method. The single-molecule sequencing of DNA was accomplished following rapid developments over the last three decades, and has been extensively applied in the single-molecule sensing of biomolecules, including peptides and proteins. This paper discusses the importance of introducing nanopore-based single-molecule experiments into university classrooms and expounds on the specific content and implementation model for teaching. This innovative experimental course adopts the teaching mode of "integration of science and education" for second- and third-year undergraduates with some background in chemistry and biochemistry. The teaching plan has been carefully designed and is continuously being optimized according to teaching practices. We integrated the latest achievements in nanopore electrochemistry and related interdisciplinary fields into classroom teaching to expand students' horizons and stimulate their interests in scientific research. In addition, students were encouraged to collaborate on experimental assignments and brainstorm, which could help cultivate their academic thinking capability and comprehensive innovation ability.
