Plasmonic Nanomaterials on the Way to Personalized Medicine

【Abstract】

Nanoplasmonics involves the manipulation of light using materials with significantly smaller sizes than the radiation wavelength. This usually involves nanostructured metals, which very efficiently absorb and scatter light because of their ability to support coherent oscillations of free (conduction) electrons. Therefore, an essential pillar behind the development of nanoplasmonics is the great advance in fabrication methods, which have achieved an exquisite control over the composition and morphology of metal nanoparticles. Colloid chemistry has the advantage of simplicity and large-scale production, with the ability to direct not only nanoparticle morphology but also surface properties and subsequent processing via self-assembly.

納米光子學涉及使用尺寸明顯小于輻射波長的材料對光進行操縱。這通常涉及到納米結構的金屬，由于它們能夠支持自由（傳導）電子的相干振蕩，能非常有效地吸收和散射光線。因此，納米光子學發展背后的一個重要支柱是制造方法的巨大進步，它已經實現了對金屬納米顆粒的組成和形態的精致控制。膠體化學具有簡單和大規模生產的優勢，不僅能夠指導納米粒子的形態，而且能夠指導表面特性和通過自組裝進行后續加工。

This talk will provide an overview of the fabrication of “nanoplasmonics” building blocks and their integration in materials and devices that can be used for real applications in sensing and diagnostics. In particular, it will focus on the application of nanostructured plasmonic substrates comprising micropatterned Au nanoparticle superlattices and 3D-printed hybrid scaffolds, to the precise SERS detection of selected tumor metabolites which shape the cancer landscape.

本講座將概述 "納米光子學 "構件的制造及其在材料和設備中的整合，這些材料和設備可用于傳感和診斷的實際應用。它將重點介紹由微圖案的金納米粒子超晶格和3D打印的混合支架組成的納米結構等離子體基底的應用，以精確的SERS檢測選定的腫瘤代謝物，這些代謝物塑造了癌癥的面貌。
