在本研究中，使用落葵叶水提取物来合成银纳米颗粒。本研究采用绿色合成方法，合成方法无毒、成本低、环境友好。FTIR光谱用于确认存在于B叶提取物中的生物分子沿着AgNP，并且这些化合物负责Ag颗粒从微米到纳米结构。用XRD和TEM分析了AgNPs的面心立方结构和结晶性质。分别进行DLS和Zeta电位技术以找到AgNPs的尺寸和稳定性，并且使用UV利用435 nm附近的SPR峰来验证合成样品中AgNPs的存在。抗氧化性研究表明，其清除活性最高为67.88%，最低为13.71%。绿色合成的银纳米粒子具有良好的抗氧化、抗菌等生物活性，可用于生物学领域。
In this present investigation, an aqueous Basella alba leaves extract was used to synthesize AgNPs. The green synthesis approach is carried out in our work due to non-toxic, less cost, and ecofriendly methods. FTIR spectra are used to confirm the biomolecules present in B.alba leaves extract along with AgNPs and these compounds are responsible for Ag particle from micro to nanostructure. The FCC structure and crystalline nature of the AgNPs are analyzed with the help of XRD and TEM techniques respectively. DLS and Zeta potential techniques are carried out to find the size and stability of AgNPs respectively and UV is used to verify the presence of AgNPs in synthesized samples employing SPR peaks around 435 nm. The antioxidant studies expose eminent scavenging activity which ranges from 13.71% to maximum 67.88%. Green synthesized AgNPs possess well organized biological activities concerning antioxidant and antibacterial, which can be used in some biologically applications.
