nanotech is still in its infancy these tiny materials could have revolutionary potential in fields as wide as medicine, energy storage, and engineering, and could allow scientists to control matter on an atomic scale. However they may also pose a risk to human, animal and environmental health, in a similar way to how microplastics have been found to been so pervasive, invasive, and toxic. Some of the nanomaterials that have presently been synthesised or isolated have already proven to be toxic, such as fullerene, but their wider effects on the environment are still virtually unknown. Nanotechnologies involve the use of atomic or molecular materials for industrial purposes, such materials fall within the range of 1-100 nanometers, smaller than the average size of a bacterial or virus . Should we question the technology ?
