  • Plasmon resonance system, instrument, and device for measuring molecular interactions
    Patent number: 11927530
    Abstract: A plasmon resonance (PR) system, instrument, and/or device and configurations thereof for measuring molecular interactions is disclosed. In some embodiments, the PR system, instrument, and/or device is a localized surface plasmon resonance (LSPR) system, instrument, and/or device. In other embodiments, the PR system, instrument, and/or device is a surface plasmon resonance (SPR) system, instrument. The PR system, instrument, and/or device may include, for example, force feedback for reliable flow cell sealing, optical feedback for reliable flow cell sealing, local thermal control of an LSPR chip (e.g., a ring Peltier, a continuous Peltier), dual displacement pumps for constant flow delivery to a microfluidic device, a dual channel LSPR sensor, and any combinations thereof.
