Abstract

Using the previously introduced modified discrete dipole approximation (DDA) method by applying the full details of the nanoparticle and its surrounding environment, the detection sensitivity of molecules by plasmonic Rod-based nanosensors, including U-shaped and Rod-shaped structures, was investigated. In the calculations, the two factors of the magnitude of the wavelength shift and the ability to distinguish molecules with similar properties were of significant interest. The results indicated that the sensitivity of Rod-based nanostructures is significantly higher than that of spherical nanoparticles. Among the plasmonic Rod-based nanosensors, the silver U-shaped structure performs better than others. The wavelength shift of the absorption spectrum of different nanosensors for a given molecule was very different, making it possible to detect very similar molecules from each other by testing different sensors.

使用修正离散偶极近似法对棒基等离子结构传感的综合研究
利用先前引入的修正离散偶极近似(DDA)方法,通过应用纳米粒子及其周围环境的全部细节,研究了基于等离子棒的纳米传感器(包括 U 型和棒型结构)对分子的检测灵敏度。在计算过程中,波长偏移的幅度和区分性质相似的分子的能力这两个因素受到了极大关注。结果表明,Rod 型纳米结构的灵敏度明显高于球形纳米粒子。在基于杆的质子纳米传感器中,银 U 形结构的性能优于其他结构。不同的纳米传感器对特定分子的吸收光谱的波长偏移大不相同,因此可以通过测试不同的传感器来检测彼此非常相似的分子。

期刊介绍: This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
