Electrochemical determination of L-dopa at cobalt hexacyanoferrate/large-mesopore carbon composite modified electrode

► Cobalt hexacyanoferrate was electrodeposited on large-mesopore carbon modified glassy carbon electrode. ► Combined advantages of large mesoporous carbon and cobalt hexacyanoferrate. ► Enhanced electrochemical response towards L-dopa. ► Highly sensitive determination of L-dopa unperturbed by ascorbic acid.
