Abstract: Well-known as a biological small molecule, ascorbic acid (AA) is involved in maintaining the normal progress of physiological and biochemical processes in the body. Many researches have shown that a variety of diseases such as anemia, gout, and atherosclerosis are associated with changes in its concentration. AA has an important influence on the absorption, metabolism and synthesis of many biological molecules in the body, which has made it widely used in the fields of health care products, food, cosmetics and pharmaceutical preparations. Among the many detection methods of AA, spectral analysis has more advantages because of its fastness, low cost and easy operation. Nanomaterials with an average diameter of less than 100 nm play an important role in spectral analysis. In this article, several nanomaterials including quantum dots, metal nanoclusters/particles, nanocage/bar/fiber materials and nanosheet materials with the method of spectroscopy analysis, especially fluorescence spectrometry and ultraviolet spectroscopy, are introduced to detect AA in current research situation. The testing advantages and existing problems are discussed for different kinds of nanomaterials.
