Rod-shaped gold nanoparticles biosynthesized using Pb2+-induced fungus Aspergillus sp. WL-Au

Green approaches for the synthesis of metal and metal oxide nanoparticles using microbial and plant extracts

“…Apart from lead ion induction, the presence of aliphatic acids, phenols, and primary and secondary amines, especially the amine II group, has been identified as being responsible for the synthesis of rod-shaped gold nanoparticles in this study. 37…”

Effects of morphology and size of nanoscale drug carriers on cellular uptake and internalization process: a review

“…Morphology exchange during the preparation process took place from spherical GNPs to completely uniform rod morphology, displaying good attachment on mycelial surfaces. 93 MSNs, carbon dot composites, nanohydroxyapatite, polymers, metal oxide NPs, and cellulose nanocrystal systems are some examples of carriers synthesized with rod morphologies. 94 Another study reports that stabilized drug loading and particle sizes with a larger surface area to volume ratio show the most rapid release.…”

Tunable Nanomaterials of Intracellular Crystallization for In Situ Biolabeling and Biomedical Imaging

“…It was found that the induced resistance was mediated by copper oxidase CopA, which was reduced to Au(0) nanoparticles in the periplasm by the intermediate detoxification Au complex. 102,103 This is a biological way for bacteria to detoxify metal ions and an unnatural process of biomineralization. Second, there are studies on the complex structure of biosynthetic DNA−gold in Escherichia coli and Staphylococcus, which has fluorescence effect and is used for the bioresponsive fluorescence imaging of bacteria.…”

“…The effect of copper/gold mixture on bacterial biosynthesis has also been studied. It was found that the induced resistance was mediated by copper oxidase CopA, which was reduced to Au(0) nanoparticles in the periplasm by the intermediate detoxification Au complex. , This is a biological way for bacteria to detoxify metal ions and an unnatural process of biomineralization. Second, there are studies on the complex structure of biosynthetic DNA–gold in Escherichia coli and Staphylococcus, which has fluorescence effect and is used for the bioresponsive fluorescence imaging of bacteria. , Different bacteria were used to explore the biosynthesis of gold nanoparticles, revealing that different bacterial biosynthetic pathways are inconsistent, leading to differences in efficiency and gold nanostructures. − …”
