Novel microfluidic chip design provides several advantages.

David L. Shenkenberg

Various laboratory instruments can sort cells or molecules, such as viruses and proteins, by fluorescent labels or by their inherent properties. By grouping cells and molecules, these instruments can identify disease states, report drug effectiveness and enable forensic analysis or classification of cells and molecules for basic research. Microfluidic chips can sort numerous cells and molecules rapidly, yet they occupy much less space and cost much less to produce than other high-throughput sorting technologies. Although laser optical trapping using free-space optics can serve as an...Read full article

    waveguide
    A waveguide is a physical structure or device that is designed to confine and guide electromagnetic waves, such as radio waves, microwaves, or light waves. It is commonly used in communication systems, radar systems, and other applications where the controlled transmission of electromagnetic waves is crucial. The basic function of a waveguide is to provide a path for the propagation of electromagnetic waves while minimizing the loss of energy. Waveguides come in various shapes and sizes, and...
