Plasmon resonance (PR) system and apparatus, digital microfluidic (DMF) cartridge, and method for using localized surface plasmon resonance (LSPR) for analysis of samples

摘要

A plasmon resonance (PR) system and apparatus, digital microfluidic (DMF) cartridges, and methods for using localized surface plasmon resonance (LSPR) and droplet manipulation for analysis of analyte have been disclosed.For example, a PR system is provided which can include a DMF cartridge that can support both fixed LSPR sensing capabilities for analysis of analytes and LSPR sensing capabilities in solution.The DMF cartridge may include an electrode configuration for performing droplet manipulation, where droplet manipulation may be used to perform fixed LSPR sensing operations and solution LSPR sensing operations.In addition, methods are provided for performing fixed LSPR sensing operations and / or LSPR sensing operations in solution using droplet manipulation in a DMF cartridge.
