Levodopa, a widely prescribed drug in the treatment of Parkinson's disease, could inhibit luminal\u2013KIO<jats:sub>4<\/jats:sub>\u2013CdTe QDs CL reaction in alkaline solution. The inhibited CL intensity was proportional to the concentration of levodopa in the range from 8.0 nM to 10.0 \u03bcM. The detection limit was 3.8 nM. This method has been successfully applied to determine levodopa in pharmaceutical preparation and human urine and plasma samples with recoveries of 94.1\u2013105.4%. This was the first work for inhibition effect determination of levodopa using a QD-based CL method.
