Viruses are deployed by geneticists for introduction of genes into cells which are being studied and also act as a common carrier vehicle in gene therapy. It is expected that nanotechnology would give a new direction to virus technology and if seen from the materials scientists’ viewpoint, viruses can be termed as organic nanoparticles. Since viruses are being commonly used in materials sciences therefore techniques developed by life sciences has become a basis for engineering approaches towards nanomaterials. Institute of Medical Physics professor, Donath and Martin Fischlechner who is an author are reviewing the emerging uses of viruses as building blocks in nanotechnology. In the words of Martin Fischlechner: Instead of chemically engineering functions into a composite material, it may be more convenient to take advantage of nanoparticles as carriers of the desired properties. These nanoparticles can then be used as building blocks for the fabrication of a composite material with the required qualities. Engineered viruses may fulfill the role of the nanoparticles and once a convenient and general strategy to attach them to an interface is found, the setup can be standardized (the authors themselves, for instance, employ virus membrane fusion to attach biological functions to the surface of microparticles. It seems virus technology can gain a lot from the emerging field of nanotechnology.
