Abstract
for 1 nM to 10 μM and 100 μM to 10 mM of cholesterol, respectively, with an ultra-low detection limit of 1 aM, along with superior selectivity for cholesterol when exposed to various interferents such as ascorbic acid, glucose and uric acid. Also, a novel NiVP/Pi-based flexible sensor coated onto Whatman filter paper was developed and displayed superior sensitivity, even with a human blood serum sample at physiological pH.
