Material nanosizing effect on living organisms: non-specific, biointeractive, physical size effects.
Nanosizing effects of materials on biological organisms was investigated by biochemical cell functional tests, cell proliferation and animal implantation testing. The increase in specific surface area causes the enhancement of ionic dissolution and serious toxicity for soluble, stimulative materials. This effect originates solely from materials and enhances the same functions as those in a macr...
متن کاملEffects of radiation on living organisms
The term radiation is elastic. Unfortunately it has come to mean “something terrible” in ordinary conversation. Literally radiation means “anything emitted from a localized source”, but in the context of biology we mean something quite specific. Human beings live amidst a sea of radiation of all sorts. It is useful to classify these radiations according to their biological effects, especially o...
متن کاملNanosizing of drugs: Effect on dissolution rate
The solubility, bioavailability and dissolution rate of drugs are important parameters for achieving in vivo efficiency. The bioavailability of orally administered drugs depends on their ability to be absorbed via gastrointestinal tract. For drugs belonging to Class II of pharmaceutical classification, the absorption process is limited by drug dissolution rate in gastrointestinal media. Therefo...
متن کاملOn Living Organisms
A number of serious non thermal biological effects, ranging from changes in cellular function like proliferation rate changes or gene expression changes to cell death induction, decrease in the rate of melatonin production and changes in electroencephalogram patterns in humans, population declinations of birds and insects, and small but statistically significant increases of certain types of ca...
