It is now 14 years since the concept of a research center for nanotechnology was first conceived by Rick Smalley and subsequently approved by the Board of Governors of Rice University. As a consequence, the Center for Nanoscale Science and Technology (renamed the “Smalley Institute” in memory of Rick) was funded without federal or state money and the world’s first university building dedicated ...

PURPOSE This study examined the need for public communication about nanotechnologies and nanoparticles by providing a comparative analysis of the differences in risk awareness of nanotechnologies and nanoparticles between consumers and experts. METHODS A total of 1,007 consumers and 150 experts participated in this study. A questionnaire was prepared examining their awareness of nanotechnolog...

BACKGROUND Beside the promising application potential of nanotechnologies in engineering, the use of nanomaterials in medicine is growing. New therapies employing innovative nanocarrier systems to increase specificity and efficacy of drug delivery schemes are already in clinical trials. However the influence of the nanoparticles themselves is still unknown in medical applications, especially fo...

Nanotechnologies is a multidisciplinary set of techniques to manipulate matter on nanoscale level, more precisely particles below 100 nm whose characteristic due to small size is essentially different from those found in macro form materials. Regarding to these new properties of the materials there are knowledge gaps about the effects of these particles on human organism and the environment. Al...

Some engineers and scientists are either directly or indirectly involved with nanotechnology issues. Nanotechnology concerns dealing with environmental implications and regulatory compliance encompass practicing areas for these technical individuals. Areas of particular concern include current/proposed environmental regulations and procedures for quantifying both health risks and hazard risks. ...

Theory and experience emphasize that science communications between experts and nonexperts should be dialogue, not monologue. This principle guides a nanotechnology outreach program at the University of South Carolina which enables the participants to express their values and concerns to experts, and to question them. It is intended that the knowledge and confidence generated by this program wi...

The term “Nanotechnology” describes a large field of scientific and technical activities dealing with objects components small dimensions. Typically, bodies that are in–at least–two dimensions smaller than 0.1 µm regarded as “nanobjects”. By this definition, lot advanced materials, well the electronic devices, nanotechnology. In addition, many aspects molecular biotechnology macromolecular supe...

Plants are exposed to various abiotic stresses such as drought, salinity, high temperature, flooding and heavy metal stress. These stress factors have a significant negative effect on plant growth yield cause economic losses. Therefore, new approaches nanotechnology used reduce the harmful effects of these plants. Agricultural aims improve sustainability in agriculture, use water effectively pr...
