WebUnder that definition a nano-object needs only one of its characteristic dimensions to be in the range 1–100 nm to be classed as a nanoparticle, even if its other dimensions are outside that range. (The lower limit of 1 nm is used because atomic bond lengths are reached at 0.1 nm.) WebMolecular size can be expressed in terms of weight (MW) and volume (V). Both are important metrics of toxicity; in general, as molecular size increases, bioavailability and toxicity decrease [16]. For example, at MW > 1000 Da, bioavailability is negligible.
