Abstract

Abstract:

We select advanced scientific research results that are suitable for undergraduate laboratory teaching. In order to present a complete process of scientific researches for students, the preparation and characterization of inorganic materials, as well as the establishment and application of optical analysis methods are integrated in this experiment. On the basis of titanium carbide mediated in situ reduction, a label-free, visualized plasmonic sensing method was constructed to achieve highly sensitive and selective detection of silver ions. The implementation of this experiment will not only help students grasp the research paradigm of nanoanalytical chemistry and develop a habit of innovative scientific thinking, but also stimulate students' interests in studying and enthusiasm to science for serving our country.

Key words: Research-oriented comprehensive experiment, Titanium carbide, Silver ions, Label-free, Colorimetric sensing
