Relationship between size and function of natural substance particles

Abstract

All of the natural substances can be viewed as particles. According to the sizes of particles, the natural substances may be classified at six levels from small to large, and heir functional spectra can be established in the order from simple to complex. They are respectively point particles (?ppspPs), fundamental structural particles (FSPs), chemical particles (ChPs), nanoparticles (NPs), macroparticles (MPs) and celestial particles (CePs). The particles in one of these levels have their independent functional activities and interaction patterns different from those in the levels lower than them, representing a new leaping. There are very close relations between the size and functions of the particles. It is especially suitablefor biological particles. As far as the present human knowledges, the activity of the PPs is the simplest without interactions; the activities of FSPs are rather complex, their interactions result in the production of various FSPs; ChPs have more complex activities, their interactions produce inumberous sorts of ions and molecules, forming the collorful chemical world; the functional activities of NPs are much more complex than those of the ChPs, their interactions cause the production of inumberous sorts of biological NPs with the characteristics of biological phenomenon; the functional activities of MPs are the most complicated, their interactions result in the production of hundreds and southands sorts of individual living bodies with the feature of high level functional activities such as learnig, thinking and reproduction; we still know little about the functional activities of the CePs. In conclusion, the establishent of the size-function spectrum will be helpful to investigate the substance world as a whole, and reveal the interaction principles of the particles and biological essential fundamentals. © 2011 Y.
