Abstract：
As an alternative to an expensive hydrothermal reactor, in the current method a domestic pressure was used for the synthesis of silver nanoparticles (Ag NP) using tree gum, kondagogu as dual functional reductant and stabilizer by autoclaving. The formation of Ag NP was evaluated with colour transformation, UV-Visible spectroscopy (UV-Vis) and transmission electron microscopy. The formation of Ag NP by gum confirmed from the developed yellow coloration of the solution and the appearance of surface plasmon resonance peak at 408 nm in the UV-Vis. The produced NP were spherical, polydisperse, particle size ranged from 2.9-17.6 nm and the average particle size was 4.5 ± 3.1 nm. The developed method is useful for demonstration, gaining hands on experience and production of metal and metal oxide NP in resource limited small laboratories, rural colleges, startups etc.•Pressure cooker serves as an easily accessible, durable, inexpensive, electricity independent hydrothermal nanoparticle production vessel.•Autoclaving serves as a facile, ecofriendly, less energy consuming, one pot, green method with dual functional role of in situ nanoparticle synthesis and sterilization.•Production of intrinsically safe and sterile nanoparticles amenable for in vivo and in vitro biomedical applications.
摘要：
作为昂贵的水热反应器的替代品，在目前的方法中，国内压力用于使用树胶合成银纳米颗粒（AgNP），kondagogu作为双功能还原剂和稳定剂通过高压灭菌。AgNP的形成用颜色转换来评估，紫外可见光谱(UV-Vis)和透射电子显微镜。由胶状物形成的AgNP由溶液的显黄和在UV-Vis中在408nm处出现表面等离子体共振峰证实。产生的NP是球形的，多分散,粒径范围为2.9-17.6nm，平均粒径为4.5±3.1nm。所开发的方法对演示很有用，在资源有限的小型实验室中获得金属和金属氧化物NP的经验和生产，农村学院,创业公司等。•压力锅作为一个容易接近，耐用,便宜,电力独立的水热纳米颗粒生产容器。•高压灭菌作为一种方便，生态友好，更少的能源消耗，一罐,具有纳米粒子原位合成和杀菌双重功能作用的绿色方法。•生产本质安全和无菌的纳米颗粒，适用于体内和体外生物医学应用。
