In this work, we present the results of the study on the interactions between gold nanorods (GNRs) and glucose. The optical properties of GNRs have higher sensitivity to glucose compared with that of gold nanospheres. The long-wavelength bands of the GNRs obviously decrease as the concentration of glucose increases. At high glucose concentrations, the absorption peak in long-wavelength bands almost disappears, and the absorption intensities corresponding to the transverse plasmon band are also decrease. These results suggest that glucose could seriously affect the optical properties of GNRs. A possible interaction mechanism between gold nanorods (GNRs) and glucose has been proposed. Furthermore, the influence of glucose on different amount GNRs also has been studied.
在这项工作中，我们展示了关于金纳米棒（GNRs）与葡萄糖之间相互作用的研究结果。与金纳米球相比，GNRs的光学性质对葡萄糖具有更高的灵敏度。随着葡萄糖浓度的增加，GNRs的长波长带明显下降。在高葡萄糖浓度下，长波长带中的吸收峰几乎消失，并且对应于横向等离子体带的吸收强度也降低。这些结果表明葡萄糖会严重影响GNRs的光学性质。已经提出了金纳米棒（GNRs）与葡萄糖之间可能的相互作用机制。此外，还研究了葡萄糖对不同量GNRs的影响。
