Article Synopsis
- - A new electroanalytical method using disposable screen-printed carbon electrodes modified with non-toxic carbon nanodots was developed for detecting codeine in biological fluids and soft drinks.
- - Graphene quantum dots were found to be the most effective modifier, allowing for precise codeine measurement with low detection limits and good accuracy in saliva samples.
- - This cost-effective and portable method can directly analyze soft drinks for codeine without needing sample preparation, making it useful for identifying potential drug adulteration in beverages.
Direct coupling sample preparation with mass spectrometry has risen as a reliable analytical strategy in bioanalysis as it provides a high sample throughput. This approach avoids an exhaustive separation step, thus being cost-effective compared to the traditional analytical workflow. The selectivity and sensitivity levels rely on the mass spectrometric analysis and the appropriate selection of the sample preparation.
