5053 150 Co3O4@β-CD NPs detection of L-Ascorbic acid L-Ascorbic acid Color 0.01-0.6 mM 1.09 μM 96.8% - 113.0% Besides, in order to investigate the precision of Co3O4@β-CD NPs detection method, recovery experiments were made by adding a serious of AA solution with different concentration. As shown in Table S3, the average recovery of all the samples was range from 96.8% to 113.0%.
