Nanoparticles are interesting:possessing properties which significantly differ from those of other larger particles.Natural nanoparticles are formed from magma spewing volcanoes;others are formed by forces such as of oceanic breakers,tides,river currents,etc.But the most complex of all the systems is the "nanome",i.e.the totality of nanoparticles in a living system.Moreover, using DLS technique it is seen that the natural nanoparticles (high % of approx.90%) in invertebrate(silkworm) haemolymph occur mostly at a size range of approx. 10-15nm while that in vertebrate serum they constitute approx. size range of 50-100nm and in plants is 200nm approx.Here is interesting evolutionary trend.Again,Blue-green algae in ponds have much less average size range(of approx. 200–250nm at 95–98%) of the nanoparticles than the Blue-green algae occurring in hot springs (having size range of approx.600–700nm at 98-100%).The evolutionary significance of these results has not been...
