Environmentally Friendly Nanotechnology using Fungi

Nanotechnology is a rapidly developing science and a number of methods are now available for producing nanoparticles. However, some of these methods employ high energy requirements, low material conversions and the use of hazardous chemicals. Hence, there is a growing need to develop eco-friendly nanoparticle synthesis methods.
Biosynthetic methods such as those that employ plant extracts or microorganisms have emerged as viable alternatives to physical and chemical synthetic procedures.

Fungi (including Aspergillus) are emerging as a prime candidate to produce nanoparticles in a far less environmentally damaging ways. This development is great news as nanotechnology is already proving to be of great use in advancing medical techniques for diagnosis and treatment, allowing for efficient drug delivery in places that have always been difficult to reach - a simple topical application of nano-drug on the skin for example is effective at getting the drug travelling deep through tissue to its target - in the past chemical solvents have had to be used for similar purposes and patients have had to tolerate toxic side effects.
