The performance of nanotechnology can be influenced by several factors, including the size, shape, and surface chemistry of the nanomaterials. Additionally, the synthesis method, the presence of defects, and the interaction of nanomaterials with their environment can play significant roles. For example, smaller nanoparticles often exhibit higher reactivity due to their larger surface area-to-volume ratio, but may also be more prone to aggregation, which can reduce their effectiveness.
