The chemical synthesis of nanoparticles can involve and generate toxic materials. Here, we present for the first time, a one pot direct route to synthesize gold nanoparticles (AuNPs) using natural cacao extract as both a reducing and stabilizing agent. The nanoparticles were characterized by UV-visible spectroscopy (UV-VIS), dynamic light scattering (DLS), and transmission electron microscopy (TEM); and have excellent biocompatibility with human primary dermal fibroblasts.
纳米颗粒的化学合成可能涉及并产生有毒物质。在此，我们首次展示了一种一锅直接法，使用天然可可提取物作为还原剂和稳定剂来合成金纳米颗粒（AuNPs）。通过紫外可见光谱（UV-VIS）、动态光散射（DLS）和透射电子显微镜（TEM）对纳米颗粒进行了表征；并且它们与人类原代表皮成纤维细胞具有出色的生物相容性。
