Abstract

This study reports the biological synthesis of platinum nanoparticles (PtNPs) using leaf extracts of kaffir lime (Citrus hystrix DC), common basil (Ocimum basilicum Linn) and fragrant pandan (Pandanus amaryllifolius Roxb). These extracts contain sugars, terpenoids, polyphenols, alkaloids, phenolic acids, and proteins, which play an essential role in reducing Pt (IV) solutions to platinum nanoparticles (PtNPs). The PtNPs were extensively characterized, exhibiting spherical morphologies and particle sizes between 20 and 80 nm as indicated by TEM imaging. As shown by the UV–Visible Spectroscopy, the maximum absorption of platinum nanoparticles is at 256 nm. Furthermore, the electrochemical sensor exhibits good analytical performances in detecting glycated hemoglobin (HbA1c) in the real samples.

生物合成铂纳米粒子（PtNPs）的物理化学方面：植物叶基提取物作为还原剂的影响

本研究报告了利用卡菲尔酸橙（Citrus hystrix DC）、普通罗勒（Ocimum basilicum Linn）和香丹（Pandanus amaryllifolius Roxb）的叶提取物进行铂纳米粒子（PtNPs）的生物合成。这些提取物含有糖类、萜类、多酚类、生物碱、酚酸和蛋白质，在将铂 (IV) 溶液还原成铂纳米粒子 (PtNPs) 的过程中发挥了重要作用。这些 PtNPs 具有广泛的特征，如 TEM 成像所示，呈球形，粒径介于 20 纳米和 80 纳米之间。紫外可见光谱显示，铂纳米颗粒的最大吸收波长为 256 纳米。此外，该电化学传感器在检测实际样品中的糖化血红蛋白（HbA1c）方面表现出良好的分析性能。
