Fungal-Based Nanotechnological Applications in Developing Biomaterial and Bioenergy: Recent Progress and Future Outlooks

The development of safe, eco-friendly, and cost-efficient methods for nanoparticle production is a crucial objective of sustainable nanotechnology. Mycosynthesis, the biological synthesis of nanoparticles utilizing fungi, in particular, is uniquely suited for this task because of their capacity to secrete numerous enzymes and simplify downstream processing. As natural bioengineers, fungi facilitate the creation of nanoparticles with high biocompatibility and minimal environmental impact. This chapter explores how mycosynthesized nanoparticles address the efficiency gaps inherent in traditional energy conversion. Mycosynthesis nanotechnology addresses the efficiency gaps in the traditional conversion. With world energy demands outperforming fossil fuel reserves, fungal-mediated nanoparticles serve as a high-efficiency catalyst to enhance bioenergy production by increasing active reaction sites and improving the breakdown of lignocellulosic biomass. Potential applications in the development of new biomaterials derived from fungal mycelium have captured the attention of both the scientific community and society. The notable ability of mycelium networks to self-construct and aggregate can be used to produce diverse biomaterials. This chapter comprehensively explores mycosynthesis-based nanoparticle-mediated natural polymer-based materials, focusing on their characteristics, applications, and innovations across different sectors, including medicine, the environment, energy, textiles, and construction. With increasing concern about resource depletion and pollution, biomaterials offer a sustainable alternative to fossil-derived products. While this chapter enables us to propose a novel green pathway for industrial innovation, challenges remain regarding the processing, structure, and standardization of this emerging transdisciplinary field of knowledge. Future trends and research should focus on the optimization of fungal strains and the implementation of a standardized system to bridge the gap between laboratory success and commercial viability.
