Optical microrings boost cancer detection

Facebook X LinkedIn Email

Sensitive detection of biomolecules is of great interest for applications such as drug development, virus detection, environmental monitoring and medical diagnostics. In contrast to optical biosensors based on surface plasmon resonance, interferometers or resonant cavities, integrated silicon-on-insulator microring sensors offer fast sample preparation and measurements, even on small sample quantities, and are exceptionally scalable, which will be key for multiplex analysis. Using this technique, researchers at the University of Illinois have demonstrated reliable, label-free detection of a...Read full article

    adsorption
    The process by which a substance, usually a solid, attracts and retains on its surface the molecules of another substance.
    lithography
    Lithography is a key process used in microfabrication and semiconductor manufacturing to create intricate patterns on the surface of substrates, typically silicon wafers. It involves the transfer of a desired pattern onto a photosensitive material called a resist, which is coated onto the substrate. The resist is then selectively exposed to light or other radiation using a mask or reticle that contains the pattern of interest. The lithography process can be broadly categorized into several...
    microring resonator
    A microring resonator is a compact optical device that utilizes the resonant behavior of light within a small ring-shaped waveguide structure to selectively enhance or filter certain wavelengths of light. Microring resonators are essential components in integrated photonics and are used in various applications, including optical communication systems, sensing, and signal processing. Key features and principles of microring resonators include: Ring structure: A microring resonator consists...
