Surface-enhanced Raman scattering (SERS) is a powerful plasmonics-based analytical technique for biosensing. SERS effect relies on nanostructures that need to be designed to maximize enhancement factors and molecular specificity. In addition to numerical modeling, an analytical tool capable of imaging localized enhancement would be an added value.

在本简报中介绍了 SZ-100 的测量数据，通过碳涂层电极电位槽，可有效地对蛋白质的Zeta电位进行测量。

众所周知，胰岛素是一种由胰腺产生的蛋白质激素，是基本代谢过程中所必需的激素。对于胰岛素的稳定性和聚集性等性能检测显得尤为重要，已有文献报道了通过荧光激发发射矩阵(EEMs)和紫外-可见吸收光谱（UV-Vis）来研究。[1]目前，商业治疗胰岛素主要分为两类: 速效胰岛素和长效胰岛素。相比于长效胰岛素，速效胰岛素在蛋白质序列中只有1到3个残基。

Gold nanorods are rod-shaped gold nanoparticles. Fig. 1 shows that gold nanorods have two surface plasmon bands in the directions of the short and long axes derived from their anisotropic shapes.
