Here we report a facile and novel bio-synthesis technique, using algal extract to reduce silver metal ions into Ag/AgCl nanoparticles. Different concentrations of metallic precursors of silver nitrate (0.1 mM, 0.2 mM, 0.5 mM and 1 mM) were tested with alcoholic extract prepared from biomass of sp. for nanoparticle biosynthesis which was screened out of four species namely sp., , sp. and . The biomolecules present in the alcoholic extract assisted in the synthesis of nanoparticles by reducing the metallic salt to metal ions and acting as capping agents in order to stabilize the particles. The synthesized particles were characterized for physico-chemical properties. DLS analysis of particles prepared from sp. shows the particles with size of 90.6 nm. These biosynthesized nanoparticles show great potential applications in antibacterial activity.
在此，我们报告一种简便且新颖的生物合成技术，即使用藻类提取物将银金属离子还原为Ag/AgCl纳米颗粒。用从四种藻类物种（分别为 、 、 、 ）中筛选出的 物种的生物质制备的醇提取物，测试了不同浓度的硝酸银金属前体（0.1 mM、0.2 mM、0.5 mM和1 mM）用于纳米颗粒生物合成。醇提取物中存在的生物分子通过将金属盐还原为金属离子并作为封端剂来稳定颗粒，从而辅助纳米颗粒的合成。对合成的颗粒进行了物理化学性质表征。对由 物种制备的颗粒进行的动态光散射分析表明，颗粒大小为90.6 nm。这些生物合成的纳米颗粒在抗菌活性方面显示出巨大的潜在应用。
