171 | HS-PtNPs | These obvious advantages prompted us to explore the practical use of HS-PtNPs. The pyridine ring of isoniazid has strong reductive hydrazyl substitution, which can compete with TMB for the catalytic site of HS-PtNPs (Scheme 1). The introduction of isoniazid in HS-PtNPs-catalyzed oxidation process of TMB results in a lower efficiency and colorless reaction in TMB oxidation. | isoniazid | Color | 2.5-250 | μM | 1.7 | μM | 95%-103% |
