Although many enzyme based assays have been developed for quantitation of uric acids, most of the biological reagents are only stable for 30 days after opening even stored at 2-8 °C. To overcome this short-lasting problem, long-lasting (more than two years), easily stored and cost-effective nonenzymatic C-dots prepared from PEI through a simple hydrothermal method were developed. Experimental results reveal that the sensitivity of the PEI C-dot assay for uric acid is higher than that of reported fluorescece and enzyme based sensors. Copyright ?
