The proposition of bio-material based soft hydrogel scaffold formation is one of the pivotal triggers to have the functionally suitable nano-bio composite. In this work, calf-thymus DNA (CT-DNA) and water-exfoliated 2D graphene oxide (GO) nanosheets have been executed towards the formation of nano and bio-material based flexible supramolecular hydrogel structure to achieve nano-bio functionality. Herein, calf thymus DNA and 2D GO nanosheets meditated a supramolecular hydrogel has been employed for the sun-ray directed synthesis of supramolecular hydrogel capped functional silver nanoparticles through a green synthetic protocol by reducing Ag(I) to Ag(0) without applying any added reducing agents. The CT-DNA and 2D GO nanosheets meditated a supramolecular hydrogel capped well-designed Ag-NPs (Ag-NPs@GO-DNA) have been employed for the production of smart ultrafine bacteria-mediated nano-bio composites. In this presentation, Gram + ve bacteria (Bacillus subtilis) and Gram -ve bacteria (Escherichia coli) have been chosen as the competent living ingredients for offering new class of Ag-NPs with considerable stability through exploiting the catalytic effects of the bacteria on Ag-NPs@GO-DNA.

基于生物材料的软水凝胶支架形成的提议是具有功能合适的纳米生物复合材料的关键触发因素之一。在这项工作中，小牛胸腺 DNA (CT-DNA) 和水剥离的 2D 氧化石墨烯 (GO) 纳米片已被用于形成基于纳米和生物材料的柔性超分子水凝胶结构，以实现纳米生物功能。在此，小牛胸腺 DNA 和 2D GO 纳米片冥想超分子水凝胶已被用于通过绿色合成方案通过将 Ag(I) 还原为 Ag(0) 而不应用任何添加的太阳射线定向合成超分子水凝胶覆盖的功能性银纳米粒子还原剂。CT-DNA 和 2D GO 纳米片冥想了一个超分子水凝胶覆盖的精心设计的 Ag-NPs (Ag-NPs@GO-DNA) 已被用于生产智能超细细菌介导的纳米生物复合材料。在本演示文稿中，革兰氏 + ve 细菌 (通过利用细菌对 Ag-NPs@GO-DNA 的催化作用，枯草芽孢杆菌( Bacillus subtilis ) 和革兰氏杆菌 ( Escherichia coli ) 被选为活性活性成分，提供具有相当稳定性的新型 Ag-NPs。
