The utilisation of plasmonic effects in metallic nanostructures is gaining importance for applications in molecular sensing. Of special interest is the local field enhancement effect, which enables surface-enhanced Raman scattering and significantly boosts the sensitivity of the Raman technique. For in vivo biological research, the ability to excite the resonance of localised surface plasmon-polaritons within the biological window is often desired. A new nanostructure called the nano-crescent is introduced and exhibits strong plasmonic activities within the biological window using a novel intra-particle plasmonic coupling scheme.
金属纳米结构中等离激元效应的利用在分子传感应用中日益重要。特别值得关注的是局部场增强效应，它能实现表面增强拉曼散射并显著提高拉曼技术的灵敏度。对于体内生物学研究，通常希望具备在生物窗口内激发局域表面等离激元 - 极化激元共振的能力。一种名为纳米月牙的新型纳米结构被引入，它通过一种新颖的粒子内等离激元耦合方案在生物窗口内展现出强大的等离激元活性。
