合成Bio-Nano复合膜及其应用在过滤和灭菌的热不稳定的材料

文摘

纳米技术是快速增长的科学与各种应用在生活的各个领域。纳米材料被广泛研究的独特的物理化学性质,如抗菌,由于他们的不寻常的界面效果。众所周知,银的纳米形式已经广泛的应用在纳米技术领域以来,银纳米粒子(AgNPs)可以使金属的生物相容性和低毒性对哺乳动物的细胞和组织。AgNPs有一个非常大得相对表面积与体积,从而增加他们接触细菌或真菌,大大提高他们的杀菌和抑菌效果。雷竞技网页版这个项目试图提供另一种方式使用的昂贵的技术,如超滤和微滤过滤和消毒热不稳定物质的探索领域的纳米技术。bio-nano复合薄膜制造的目标是提供一个更好的方法过滤和灭菌相比传统滤波器同行和基础聚合物。这样的电影会在工业规模经济和商业应用程序可以更容易使用。一个新颖的方法实现灌注AgNPs成微晶纤维素(MCC),咖喱叶(Murrayakoenigii)提取。银离子的活性降低咖喱叶提取物是探索原位浸渍ofAgNPs MCC。咖喱叶提取物引起银离子还原成银,有核的银纳米颗粒的微晶体纤维。 The bioreduction of silver nanoparticles and its impregnation was investigated through various characterization techniques. The characterization of AgNP impregnated MCC powder confirms the formation of Ag structure on microcrystalline cellulose. The MCC impregnated with AgNPs was used to prepare a film after testing for its anti-microbial activity. The film was characterized for its pore size. Lastly the film was assessed for anti-microbial activity for it to be used as a filter.AgNPs were successfully synthesized which was confirmed through UV-visible analysis. The AgNPs were impregnated into MCC as revealed by analysis. The size of the nanoparticles was determined to be in the range of 5-20nm.The film was fabricated through solvent casting method using sodium alginate as the polymer. The anti-microbial analysis gave positive results and thus could be used as an alternate method for the sterilization of heat labile substances.
