Mesoporous NiCo 2 S 4 nanoflakes as an efficient and durable electrocatalyst for non-enzymatic detection of cholesterol
The detection of cholesterol is very crucial in clinical diagnosis for rapid and accurate monitoring of multiple disease-biomarkers. There is a great need for construction of a highly reliable and stable electrocatalyst for the efficient detection of cholesterol. In this work, mesoporous NiCo 2 S 4...
