We have investigated the sustainable synthesis of silver nanoparticles (AgNPs) using blueberry (Vaccinium corymbosum L.) ethanolic extract from the point of view of the intervening metabolites. An extensive NMR metabolomic approach based on nuclear magnetic resonance (NMR) spectroscopy and headspace-solid phase microextraction (HS-SPME) followed by gas chromatography/quadrupole-mass spectrometry (GC–qMS) has been directed in order to ascertain for the first time the involved bioactive molecules as those responsible for the synthesis of AgNPs. The green process was monitored through UV–vis spectrophotometry, and a plethora of techniques such as EDX, XRD, XPS, TEM, SEM, and DLS were used to confirm the formation of the AgNPs. The successful synthesis was indirectly proven by their antibacterial activity against Gram-positive Streptococcus pyogenes and Gram-negative bacteria Salmonella typhi.

通过核磁共振代谢组学揭示负责可持续合成纳米级银颗粒的活性生物分子
我们研究了使用蓝莓（Vaccinium corymbosum）可持续合成银纳米颗粒（AgNPs）从中间代谢产物的角度来看，L。）乙醇提取物。为了首次确定基于核磁共振（NMR）光谱和顶空-固相微萃取（HS-SPME），然后进行气相色谱/四极杆质谱（GC-qMS）的广泛的NMR代谢组学方法所涉及的生物活性分子是负责合成AgNP的分子。通过紫外可见分光光度法监测绿色过程，并使用多种技术（例如EDX，XRD，XPS，TEM，SEM和DLS）确认AgNP的形成。合成成功的秘诀是它们对革兰氏阳性化脓性链球菌和革兰氏阴性菌伤寒沙门氏菌具有抗菌活性。
