• Resumen

  • A microfluidics-based laboratory experiment for the analysis of DNA fragments in an analytical undergraduate course is presented. The experiment is set within the context of food species identification via amplified DNA fragments. The students are provided with berry samples from which they extract DNA and perform polymerase chain reaction (PCR) with strawberry-specific primers. The resulting PCR products are analyzed using the Agilent Bioanalyzer. Using the raw data, the students are tasked to identify the strawberry sample. This course serves as a practical introduction into microfluidic-based capillary gel electrophoresis as well as a primer for biomolecular DNA analysis.
