ABSTRACT

Methods of producing nanoparticles, called nanotechnologies, have inspired lively interest over the recent years due to the broad possibilities for application of nanoparticles in numerous fields, including electronics, information technology, biotechnology, medicine, pharmacy, cosmetology and others. Nanoparticles are defined as particles which may occur in various shapes and which have at least one dimension smaller than 100 nm. Depending on the process of creation we can differentiate between natural nanoparticles occurring in the environment and designed nanoparticles, which are man-made. Designed nanoparticles are characterised by special physical properties which make them suitable for biomedical applications, among others. An example of such an application is the use of silver nanocomposites, which in a micronised form display a strong bacteriostatic and bactericidal effect. Graphene, the latest achievement of nanotechnology with unique mechanical and physical properties, is another material which raises much interest among researchers. The dynamic development of numerous directions in modern technologies based on nanotechnologies is an indisputable sign of progress. The discovery of the unique properties of nanomaterials opens wide possibilities for numerous applications; however, it also requires comprehensive research to ensure they are safe to use.
