摘要

Abstract > The search for biocompatible nanoparticles with vast applicability has impacted on exploration of various biomaterials for the synthesis of mono and bimetallic nanoparticles. Xylanase is widely regarded as an industrially important enzyme but its potentials in nanotechnological applications are yet to be fully explored. The current study investigates the exploit of xylanases of Aspergillus niger L3 (NE) and Trichoderma longibrachiatum L2 (TE) produced through valorization of corn‐cob, to synthesize silver‐gold alloy nanoparticles (Ag‐AuNPs). Characterization of the Ag‐AuNPs involved UV–vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), and field emission scanning electron microscopy and transmission electron microscopy, while their prospective use as antimicrobial, antioxidant, catalytic, anticoagulant, and thrombolytic agents were studied. The biosynthesized Ag‐AuNPs were ruby red and light purple with surface plasmon resonance at 520 and 534?nm for NEAg‐AuNPs and TEAg‐AuNPs, respectively; while FTIR showed that protein molecules capped and stabilized the nanoparticles. The Ag‐AuNPs were anisotropic with spherical, oval, and irregular shapes having sizes ranging from 6.98 to 52.51?nm. The nanoparticles appreciably inhibited the growth of tested clinical bacteria (23.40–90.70%) and fungi (70.10–89.05%), and also scavenged 2,2‐diphenyl‐1‐picrylhydrazyl (48.51–53.79%) and hydrogen peroxide (80.5–95.50%). Furthermore, the Ag‐AuNPs degraded malachite green (91.39%) and methylene blue (47.10%). Moreover, the Ag‐AuNPs displayed outstanding anticoagulant and thrombolytic activities using human blood. This study further emphasizes the significance of xylanases in nanobiotechnology as it has established the potential of xylanases to synthesize Ag‐AuNPs, which is being reported for the first time.

richoderma longibrachiatum </ i> 通过玉米棒的瓣膜制备L2（TE），合成银 - 金合金纳米粒子（Ag-AuNP）。 AG-AUNP的表征涉及UV-Vis光谱，傅里叶变换红外光谱（FTIR），以及场发射扫描电子显微镜和透射电子显微镜，而研究其前景用作抗微生物，抗氧化剂，催化剂，抗凝血剂和溶血剂。生物合成的AG-AUNP分别是用520和534Ω的表面等离子体共振的红宝石红色和浅紫色，分别用于NEAG-AUNP和TEAG-AUNPS;虽然FTIR显示蛋白质分子盖住并稳定纳米颗粒。 AG-AUNPS是具有球形，椭圆形和不规则形状的各向异性，其尺寸范围为6.98至52.51Ω。纳米粒子明显抑制了测试临床细菌的生长（23.40-90.70％）和真菌（70.10-89.05％），也可清除2,2-二苯基-1-富铬（48.51-53.79％）和过氧化氢（80.5-95.50）％）。此外，AG-AUNPS降解了孔雀石绿色（91.39％）和亚甲基蓝（47.10％）。此外，AG-AUNPS使用人血显示出突出的抗凝血剂和溶栓活性。本研究进一步强调了木质化学酶在纳米能源中的意义，因为它已经建立了木聚糖酶的潜力合成了Ag-AuNP，这是首次报告的。
