纳米技术可用于诊断技术、药物输送、防晒霜、抗菌消毒剂和减少废物的友好制造过程。绿色纳米技术的发展引起了研究人员对生态友好的纳米颗粒生物合成的兴趣。在研究中，银纳米粒子的合成从水银硝酸盐（1 mM）通过一个简单的和生态友好的方法，使用肉桂作为还原剂和稳定剂。水溶性银离子在叶液中被还原，绿色合成的银纳米颗粒粒径在20 ~ 30 nm之间。采用紫外可见分光光度计、X射线衍射、场发射扫描电子显微镜（FESEM）及能谱仪（EDAX）和傅里叶变换红外光谱（FTIR）对生物还原银纳米粒子进行了表征。进行FTIR研究以识别负责银纳米颗粒的有效稳定的可能的生物分子，并针对革兰氏阳性、革兰氏阴性微生物筛选其抗微生物活性。该方法可用于快速和生态友好的生物合成的稳定的银纳米粒子的尺寸范围从20至30 nm具有抗菌活性，这表明它们可能的应用在医学领域。
Nanotechnology can be useful in diagnostic techniques, drug delivery, sunscreens, antimicrobial sanitizer and a friendly manufacturing process that reduce waste products. Development of Green Nanotechnology is generating interest of researchers towards eco-friendly biosynthesis of nanoparticles. In the research study silver nanoparticles were synthesized from aqueous silver nitrate (1 mM) through a simple and eco-friendly method using cinnamon as reductant and stabilizer. The aqueous silver ions when exposed to leaf broth were reduced and resulted in the green synthesis of silver nanoparticles ranges from 20 nm to 30 nm. The bio reduced silver nanoparticles were characterized by UV-Vis spectrophotometer, X ray diffraction, FESEM with EDAX and Fourier transform infra red (FTIR) spectroscopy. The FTIR study was carried out to recognize the possible biomolecules responsible for proficient stabilization of silver nanoparticles and their antimicrobial activity was screened against both gram positive, gram-negative microorganisms. The method can be used for rapid and eco-friendly biosynthesis of stable silver nanoparticles of size range from 20 to 30 nm possessing antimicrobial activity suggesting their possible application in the field of medicine.
