Abstract
The microskin is reticulated at a mol. level which comprises an ordered arrangement of absorption/repulsion sites (spacing pref. of the same order of magnitude as the mean free path of Brownian motion of the mols. to be retained; esp. ca 1-20 microns) of at least 3 different energy levels for mols. being retained. The microskin pref. comprises a multivalent ion, esp. Al, P, Si or Ca, and is esp. a Ca apatite or Ca aconitate.
