The main methods of synthesizing nanoparticales are chemical and physical approaches that are often expensive and potentially harmful to the environment. The present study is devoted to the possibility of the synthesis of silver nanoparticales and zinc oxide from silver nitrate and zinc acetate using basilica plant extracts. The products obtained are characterized by various analysis techniques, such as UV/V, XRD, MEB-EDX, FTIR, and RAMAN. These analyzes confirm the crystalline nature of AgNps and ZnONps. These crystalline powders having effective biological activities regarding the antioxidant and antibacterial, which could be used in several biological applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20synthesis" title="green synthesis">green synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-reduction" title=" bio-reduction"> bio-reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=metals%20nan%20Oparticales" title=" metals nan Oparticales"> metals nan Oparticales</a>, <a href="https://publications.waset.org/abstracts/search?q=Plants%20extracts" title=" Plants extracts"> Plants extracts</a> </p> <a href="https://publications.waset.org/abstracts/142677/green-synthesis-characterization-and-application-of-zinc-oxide-and-silver-oxide-nonparticipants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">200</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Nanoparticles on Biological Biomarquers Models: Paramecium Tetraurelia and Helix aspersa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Djebar">H.

Objectives of our research concern the determination of NPs ZnO, TiO2, AlO2, and FeO2 effect on ciliate protist freshwater Paramecium sp and Helix aspersa. The result obtained show that NPs increased antioxidative enzyme activity like catalase, glutathione 鈥揝-transferase and level GSH. Also, cells treated with high concentrations of NPs showed a high level of MDA. In conclusion, observations from growth and enzymatic parameters suggest on one hand that treatment with NPs provokes an oxidative stress and on the other that snale and paramecium are excellent alternatives models for ecotoxicological studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NPs" title="NPs">NPs</a>, <a
