研究目的
To summarize recent advances in optical analysis using plasmonic nanoparticles (e.g., gold and silver) that have been reported since 2015, focusing on LSPR properties, optical analysis in homogeneous solution based on colorimetry and fluorimetry, and single plasmonic nanoparticle analysis with enhanced detection sensitivity.
研究成果
The review provides an in-depth analysis and summary of the results, emphasizing interpretability and forward-looking nature. It highlights the successful analysis of various targets in homogeneous solution and at the single-nanoparticle level using plasmonic nanoparticle-based optical systems, while also pointing out the challenges and future trends in the field.
研究不足
The technical and application constraints of the experiments, as well as potential areas for optimization, are discussed. Challenges include the poor stability of plasmonic nanoparticles in complex media, the difficulty in simultaneous detection of multiple targets, and the need for uniform morphology of plasmonic nanoparticles for single-nanoparticle assays.
