纳米粒子的生物合成由于其生态友好的优点而成为传统合成方法的一种有前途的替代方法，并且所涉及的生物协议仍需要进一步澄清。本研究首次从统计学的角度证实了氯金离子与相关生物组分之间的静电力或离子键相互作用，并表明还原糖和类黄酮都是负责Au（III）转化为Au（0）的重要还原剂。结果还表明，这些蛋白质不是还原剂，但它们可能是金纳米颗粒（GNP）生物合成的保护剂。此外，叶面液的抗氧化能力与其将Au（III）还原为Au（0）的能力之间存在显著的线性关系。此外，基于对生物合成GNP的尺寸/形状分布的箱形图的初步研究揭示，具有更高程度的尺寸均匀性的金纳米球倾向于被含有更高含量的还原糖/类黄酮和蛋白质的叶肉汤促进。否则，即，对于具有较低含量的上述生物化合物的那些肉汤，倾向于制造具有较宽尺寸分布的球形GNP或甚至金纳米三角形。(See补充材料1）
Biosynthesis of nanoparticles has arisen as a promising alternative to conventional synthetic methodologies owing to its eco-friendly advantages, and the involved bioprotocol still needs further clarification. This research, for the first time from the standpoint of statistics, confirmed an electrostatic force or ionic bond-based interaction between the chloroauric ions and the involved bioconstituents and manifested that reducing sugars and flavonoids were both important reductants responsible for conversion of Au(III) to Au(0). The result also demonstrated that the proteins were not the reducing agents, yet they might be protection agents in biosynthesis of gold nanoparticles (GNPs). Besides, a significant linear relationship was found between the anti-oxidant ability of the foliar broths and their capability to reduce Au(III) into Au(0). Furthermore, the preliminary investigation based on the boxplot on the size/shape distribution of the biosynthesized GNPs revealed that gold nanospheres with higher degree of homogeneity in size tended to be promoted by foliar broths containing higher content of reducing sugars/flavonoids and proteins. Otherwise, i.e., for those broths with lower content of the above biocompounds, sphere GNPs of wider size distribution or even gold nanotriangles tended to be fabricated.(See supplementary material 1)
