Further, cells are roughly between 100 nanometers and one micron (1000 nanometers). If one were to insist on grinding these materials down to meet the "nano" threshold of less than 100 nanometers, the cells would die, and they would lose their therapeutic effect.
而一個細胞的大小，大約在一百微米到一微米（一千奈米）之間，如果為了符合以一百奈米為上限的奈米化標準，硬要研磨打碎，細胞就「死」了，藥性也不復存在。
