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…mehr

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 derived yet.By simply using Foxtail grass extract,it could be said that the proteins so abundant in animal serum or haemolymph is not a prominent composite of the extract.
