We studied the optical response from more than 13, 000 individual photosynthetic pigment-protein complexes interacting with spherical gold nanoparticles. The nanodots were arranged in a quasi-hexagonal array by diblock copolymer micellar nanolithography. Exciting the proteins within the spectral range of the nanoparticles' plasmon resonance yields a clear enhancement of the protein fluorescence intensity, whereas excitation far out of the plasmon resonance features no effect. This result indicates a strategy for the construction of efficient hybrid light-harvesting devices.
我们研究了与球形金纳米粒子相互作用的超过 13000 个单个光合色素-蛋白质复合物的光学响应。纳米点通过两亲嵌段共聚物胶束纳米光刻术排列成准六边形阵列。在纳米粒子等离子体共振的光谱范围内激发蛋白质，会导致蛋白质荧光强度的明显增强，而在等离子体共振之外激发则没有效果。这一结果为构建高效的混合光收集器件提供了一种策略。
