Spatially, human attention is focused on meter level and its fractions. It cannot entrain anything logarithmically beyond a itcertain range (kilometer on one end and millimeter on the other) However, matter, including biological matter. this range and beyond. Human red blood cells (RBC) are in the range of 10-6 m, protein molecule 10-9 m (nanometer), and atom 10 1 (quantum level), but the smallest spatial level that science and technology can fathom at the moment is Planck level. 10 35 m. The usual drug particle size is in the range of 10 4, which is around 10 times larger than RBC. and therefore, it is not surprising that majority of drug is wasted, not only decreasing its efficacy but also leading to its distribution to nontarget areas, increasing unwar ranted side effects
