Abstract. A simple, low-cost, and ecofriendly method of obtaining silver nanoparticles was obtained from AgNO3 in dilution for the first time with a habanero pepper infusion. Two sets of experiments were carried out. The samples obtained in the first experiment were analyzed by SEM and TEM. Results showed that the samples prepared using 0.001 M and 0.005 M of AgNO3 and particles with an average size of 19.3 and 26.4 nm were obtained. Furthermore, the nanoparticles prepared with 0.005 M showed an absorption peak shifted toward a larger wavelength, and according to its distribution, it also exhibited larger particle sizes. In the second experiment, different concentrations of habanero pepper (10, 50, and 100 mL) were explored and the pH and oxidation reduction potential were monitored. The sample with 100 mL concentration showed the most intense absorption peak and the highest decrease in pH, which is explained by biomolecules deprotonation.

使用哈瓦那辣椒 (Capsicum chinense Jacq.) 的生物分子作为还原剂合成银纳米粒子

摘要。首次用哈瓦那辣椒浸液稀释的 AgNO3 获得了一种简单、低成本且环保的获得银纳米粒子的方法。进行了两组实验。通过SEM和TEM分析在第一个实验中获得的样品。结果表明,获得了使用 0.001 M 和 0.005 M 的 AgNO3 制备的样品,并且获得了平均粒径为 19.3 和 26.4 nm 的颗粒。此外,用 0.005 M 制备的纳米颗粒表现出吸收峰向更大波长移动,并且根据其分布,它也表现出更大的粒径。在第二个实验中,研究了不同浓度的哈瓦那辣椒(10、50 和 100 毫升),并监测了 pH 值和氧化还原电位。
