摘要

摘要:本文报道了一种利用死蚊(库蚊)肉汤的新技术,认为死亡的动物及其组织/器官废物也可以参与纳米颗粒的合成,因为只有生物体是死亡的,而制造它们的分子是死亡的。一个非常简单的环境友好的方案,利用库蚊的肉汤产生硫系(CdS)纳米颗粒。x射线和透射电镜分析确定了CdS纳米颗粒的形成。发现了单个纳米颗粒以及极少数大小为2-14纳米的聚集体。紫外可见光谱研究显示表面等离子体在426 nm处发生共振。在紫外可见光谱和光致发光光谱(PL)中也表现出蓝移。原肌球蛋白、几丁质和金属硫蛋白可能参与了CdS纳米颗粒的生物合成。

Now the household mosquitoes (Culex Sp.) synthesize CdS nanoparticles
ABSTRACTA novel technique of utilizing the dead mosquitoes (Culex Sp.) broth is reported with a conviction that dead animals and their tissue/organ wastes too can participate in nanoparticle synthesis as only organism is dead not the molecules which make them. A very simple environment friendly protocol employing the broth of the Culex Sp. yielded chalcogenide (CdS) nanoparticles. X-ray and transmission electron microscopy analyses are performed to ascertain the formation of CdS nanoparticles. Individual nanoparticles as well as a very few aggregate having the size of 2–14 nm are found. UV-Vis spectroscopy study revealed the surface plasmon resonance at 426 nm. The product also showed blue shift in the UV-Vis and photoluminescence (PL) spectra. A possible involved mechanism for the biosynthesis of CdS nanoparticles has also been proposed in which participation of tropomyosin, chitin and metallothioneins is suggested.
