Event Description
The lateral flow immunoassay, or LFIA, has become a widely adopted method for point-of-care diagnostics due to its ease of use, portability and cost-effectiveness. However, the sensitivity of traditional gold nanoparticle-based LFIAs is often limited by the weak visual signals they generate. This presentation will explore the use of anisotropic plasmonic nanoparticles, such as gold nanostars and gold nanocrowns, to not only enhance colorimetric detection but also improve performance in photothermal and SERS-based LFIAs. We will also discuss how this plasmonically active nanoparticle system enables enhanced sensitivity and provides an excellent platform for uncovering the unique chemistry involved in nanoparticle synthesis.
