Fungi as an efficient mycosystem for the synthesis of metal nanoparticles: progress and key aspects of research

Abstract

Nanotechnology is an emerging cutting-edge technology, which involves interdisciplinary subjects, such as physics, chemistry, biology, material science and medicine. Different methods for the synthesis of nanoparticles have been discussed here. Although physical and chemical methods have been successfully used to synthesize nanoparticles, the use of hazardous chemicals and synthesis at high temperature is a matter of concern. Hence, there is a necessity to develop eco-friendly techniques for the synthesis of nanoparticles. Biosynthesis of nanoparticles by fungi, bacteria, actinomycetes, lichen and viruses have been reported eco-friendly. Moreover, the fungal system has emerged as an efficient system for nanoparticle synthesis as fungi possess distinctive characters including high wall binding capacity, easy to culture and simpler biomass handling, etc. In this review, we have discussed fungi as an important tool for the fabrication of nanoparticles. In addition, methods and mechanism for synthesis of nanoparticles and its potential applications have also been discussed.

Mycogenic nanoparticles and their bio-prospective applications: current status and future challenges

“…As compared to bacteria, fungi have greater tolerance and uptake capacity for metals particularly in terms of binding capacity of metal salts; hence, fungal biomass is an advantage for large-scale production of nanoparticles. Including this, their downstream processing is quite easy so that it is easy to cultivate for the efficient low-cost synthesis of metal nanoparticles [42]. Various fungi have already known for the fabrication of several metal nanoparticles like Au, Ag, Pd, Cu, Zn, Ti, Fe and Pt [5].…”

Synthesis Approaches of Zinc Oxide Nanoparticles: The Dilemma of Ecotoxicity

“…Fungi are decomposers as well as parasite in nature. In intracellular synthesis, fungal biomass is incubated for a particular time period in dark along with a zinc salt solution, while in extracellular synthesis fungal filtrates are treated with the precursor solution and synthesis is assessed [75]. A number of studies are available on using fungi as ZnO synthesizer.…”

Síntese Biológica De Nanopartículas Mediada Por Micro-Organismos Endofíticos

“…Ao contrário dos métodos físicos e químicos, a síntese microbiana é rentável e favorável ao meio ambiente. Assim, a micosíntese de nanopartículas é agora um ramo importante da bionanotecnologia e é referido como miconanotecnologia (YADAV et al, 2015;OVAIS et al, 2018;SHAH et al, 2018).…”

“…Muitos fungos e bactérias são capazes de produzirem nanopartículas inorgânicas, quer seja através de rotas intracelulares ou extracelulares (LI et al, 2011), processo este que passou a ser descrito como micosíntese. Neste processo considerado ecofriendly, podem ser empregados tanto fungos como bactérias e, do ponto de vista econômico é viável e fácil (YADAV et al, 2015).…”
