  • Title: Thin-walled graphitic nanocages as a unique platform for amperometric glucose biosensor.
    Author: Guo CX, Sheng ZM, Shen YQ, Dong ZL, Li CM.
    Journal: ACS Appl Mater Interfaces; 2010 Sep; 2(9):2481-4. PubMed ID: 20722406.
    Abstract:
    A thin-walled graphitic nanocages material with well-developed graphitic structure, large specific surface area and pronounced mesoporosity was synthesized and used to construct a sensing interface for an amperometric glucose biosensor, showing a high and reproducible sensitivity of 13.3 μA mM(-1) cm(-2), linear dynamic range of 0.02-6.2 mM, and fast response time of 5 s. It was successfully used to accurately detect glucose in human serum with effective discrimination to common interference species such as dopamine, ascorbic acid, acetaminophen, and uric acid.
