This report describes important future research directions in nanoscale science, engineering and technology. It was prepared in connection with an anticipated national research initiative on nanotechnology for the twenty–first century. The research directions described are not expected to be inclusive but illustrate the wide range of research opportunities and challenges that could be undertake...

nanotechnology is the engineering of functional systems at the molecular scale which may exert a revolutionary impact on cancer diagnosis and therapy. nanotechnology is being applied to cancer in two broad areas: i) the development of nanovectors such as nanoparticles which can be loaded with drugs or imaging agents and then targeted to tumours, and ii) high-throughput nanosensor devices for de...

Commercialization of nanotechnologies entails a regulatory requirement for understanding their environmental, health and safety (EHS) risks. Today we face challenges to assess these risks, which emerge from uncertainties around the interactions of manufactured nanomaterials (MNs) with humans and the environment. In order to reduce these uncertainties, it is necessary to generate sound scientifi...

Objective (s): Nanotechnology has gained importance in recent years due to its ability in the enhancement of materials properties and other specifications such as antimicrobial properties. Nano-sized materials have been applied in various fields of dentistry. Nanotechnology can be employed in orthodontics to enhance the quality of treatment. In the current study, a comprehensive review is carri...

The shift toward online communication in all realms, from print newspapers to broadcast television, has implications for how the general public consumes information about nanotechnology. The goal of this study is threefold: to investigate who is using online sources for information and news about science and nanotechnology, to examine what the general public is searching for online with regards...

Feynman's early vision in 1959 gave birth to the concept of nanotechnology. He saw it as an unavoidable development in the progress of science and said that there is plenty of room at the bottom. Since then, nanotechnology has been part of mainstream scientific theory with potential medical and dental applications. Numerous theoretical predictions have been made based on the potential applicati...

¶1 Nanotechnology is a buzzword, which makes an exact definition tricky. But most experts agree that nanotechnology refers to technology at the nanometer scale, which is one billionth of a meter.1 To put this in perspective, one nanometer is about 100,000 times as thin as a human hair.2 But nanotechnology is more than just its small size. It also involves a new way to pursue technology. Before ...

Nanotechnology involves the fabrication, manipulation, and control of materials at the atomic level and may also bring novel uncertainties and risks. Potential parallels with other controversial technologies mean there is a need to develop a comprehensive understanding of processes of public perception of nanotechnology uncertainties, risks, and benefits, alongside related communication issues....

This study explores the image of synthetic biology and nanotechnology in comparison to agricultural biotechnology and communication technology by examining spontaneous associations with, and deliberate evaluations of, these technologies by university students. Data were collected through a self-completion online questionnaire by students from two universities in Switzerland. The survey aimed to...

After more than ten years of strategic investment research and development supported by government policies on science and technology, nanotechnology in Japan is making a transition from the knowledge creation stage of exploratory research to the stage of making the outcomes available for the benefit of society as a whole. Osaka University has been proactive in discussions about the relationshi...
