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. A quintessential QSAR for skin permeability, the Potts and Guy equation [5], relies on ...

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.) WebA nanometre is very, very small – there are a million of them in a millimetre. ‘Nano’ means ‘a billionth’ (a billion is a thousand million), so: a nanosecond is a billionth of a second.
