Dielectrophoresis is a well‐understood phenomenon that has been widely utilized in biomedical applications. Recent advancements in miniaturization have contributed to the development of dielectrophoretic‐based devices for a wide variety of biomedical applications. In particular, the integration of dielectrophoresis with microfluidics, fluorescence, and electrical impedance has produced devices and...
The detection and quantification of nucleic acid and proteomic biomarkers in bodily fluids is a critical part of many medical screening and diagnoses. However, majority of the current detection platforms are not ideal for routine, rapid, and low‐cost testing in point‐of‐care settings. To address this issue, we developed a concept for a disposable universal point‐of‐care biosensor that can detect and...
We developed a label-free biosensor based on light scattering from polystyrene beads and dielectrophoresis spectroscopy that can identify single stranded DNA. We have demonstrated this method using DNA strands with 16, 17, and 26 base pairs of nucleotides.
The isolation of target cells from biological samples such as blood, serum or urine without contamination with other cells or without loosing target cells in high-throughput is the starting point of developing effective therapy. Currently available techniques for cell isolation require extra labeling of target cells followed by lengthy isolation processes. These processes will cause to contaminate...
