Highly sensitive determination of l-glutamic acid in pig serum with an enzyme-free molecularly imprinted polymer on a carbon-nanotube modified electrode

An enzyme-free molecularly imprinted sensor with MWCNTs was developed through electrochemical polymerization using l -Glu as a template and 4,6-diaminoresorcinol as a monomer, providing a simple and accurate way for assay of l -Glu in life science.
