Abstract Microfluidics has been touted as the transformative, translational technology for point-of-care diagnostics, tissue engineering, and other biomedical applications. Despite the fact that intensive efforts have been devoted to the field in the past decades, transition of microfluidics from research laboratories into biological and clinical domains remains an elusive goal. This is due to several fundamental obstacles including the requirement of labor-intensive sample preparation procedures in most biological assays, the ineffectiveness of many standard sample preparation techniques at the microscale, the necessity of cumbersome supporting equipment, and most significantly, system integration of different sample preparation modules into a single platform. With a multifunctional electrode array that is capable of implementing hybrid electrokinetic sample preparation and SAM based electrochemical sensing, we are developing an electrokinetic bioprocessor for molecular analysis. In this talk, our ongoing effort of using the electrokinetic bioprocessor for point-of-care diagnostics including phenotypic antimicrobial susceptibility testing and genotypic identification of bacterial pathogens will be presented. |
