摘要

Abstract >Biological methods have been used to synthesize silver nanoparticles through materials such as bacteria, fungi, plants, and propolis due to their reducing properties, stabilizer role and environmentally friendly characteristic. Considering the antimicrobial activity of propolis as well as the broad‐spectrum antibacterial effects of silver nanoparticles, this study aim to describe the use of Brazilian propolis to synthesize silver nanoparticles (AgNP‐P) and investigate its antimicrobial activity. The synthesis was optimized by factorial design, choosing the best conditions for smaller size particles. AgNP‐P demonstrated a maximum absorbance at 412?nm in ultraviolet‐visible spectra, which indicated a spherical format and its formation. Dynamic light scattering demonstrated a hydrodynamic size of 109?nm and polydispersity index less than 0.3, showing a good size distribution and stability. After its purification via centrifugation, microscopy analysis corroborates the format and showed the presence of propolis around silver nanoparticle. X‐ray diffraction peaks were attributed to the main planes of the metallic silver crystalline structure; meanwhile infrared spectroscopy demonstrated the main groups responsible for silver reduction, represented by ～22% of AgNP‐P indicates by thermal analysis. Our product revealed an important antimicrobial activity indicating a synergism between propolis and silver nanoparticles as expected and promising to be an effective antimicrobial product to be used in infections. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >由于其降低性能，稳定剂作用和环保特性，已经用于通过诸如细菌，真菌，植物和蜂胶的材料合成银纳米颗粒的生物学方法。考虑到蜂胶的抗菌活性以及银纳米粒子的广谱抗菌作用，本研究旨在描述巴西蜂胶的使用合成银纳米粒子（AgNP-P）并研究其抗微生物活性。通过因子设计优化了合成，为较小尺寸的粒子选择了最佳条件。 AgNP-P在紫外线可见光谱中显示出412ΩNM的最大吸光度，这表明了球形格式及其形成。动态光散射证明了109·Nm的流体动力学尺寸和小于0.3的多分散度指数，显示出良好的尺寸分布和稳定性。通过离心纯化后，显微镜分析证实了这种形式并显示了银纳米粒子周围的蜂胶存在。 X射线衍射峰归因于金属银晶结构的主平面;同时红外光谱证明了负责银还原的主要组，〜22％的AgNP-P表示通过热分析。我们的产品揭示了一种重要的抗微生物活性，表明蜂胶和银纳米粒子之间的协同作用，如预期的，并且有希望是用于感染的有效抗微生物产品。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-15005/'>《Biotechnology Progress》</a> <b style="margin: 0 2px;">|</b><span>2019年第6期</span><b style="margin: 0 2px;">|</b><span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Barbosa Valcilaine T.&option=202" target="_blank" rel="nofollow">Barbosa Valcilaine T.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Souza Joyelanne K.
