The Nanotechnology Characterization Laboratory's (NCL) unique set-up has allowed our lab to handle and test a variety of nanoparticle platforms intended for the delivery of cancer therapeutics and/or imaging contrast agents. Over the last six years, the NCL has characterized more than 250 different nanomaterials from more than 75 different investigators. These submitted nanomaterials stem from a range of backgrounds and experiences, including government, academia and industry. This has given the NCL a unique and valuable opportunity to observe trends in nanoparticle safety and biocompatibility, as well as note some of the common mistakes and oversights of nanoformulation. While not exhaustive, this article aims to share some of the most common pitfalls observed by the NCL as they relate to nanoparticle synthesis, purification, characterization and analysis.

This is an NSF-funded (Grant No. EEC-0407237) Rice University course called "Nanotechnology: Context and Content." The goal is to teach students some basic nanoscience/nanotechnology by putting it in a social and cultural context. Students are expected to learn both some basic science and technology and at the same time, some techniques for understanding the social and cultural significance, role, and possible effects of this emerging science. Students from from all majors are encouraged to take this class. In addition, students are expected to assist each other in learning and discussing the content and the context, and to maintain respect for both the scientific and the social and cultural approaches. Many modules in this course are the result of students work in previous iterations of the class. ; This work was created using the Connexions authoring platform. This platform will be retired as of the end of 2021. This work has been migrated to PDF format for continuous access to the educational content, however any embedded links within the text to the legacy platform may no longer be accessible.

The central claims defended in this article are the following: (a) The social and ethical challenges of nanotechnology can be fully identified only if both the characteristic features of nanotechnologies and the social contexts into which they are emerging are considered. (b) When this is done, a host of significant social context issues, or issues that arise as a result of problematic features of the social contexts into which nanotechnology is emerging, become salient. (c) These issues can only be addressed by remedying the problematic features of the social contexts, which cannot be accomplished by technology design or risk management alone. (d) The U.S. National Nanotechnology Initiative's conceptualization and operationalization of responsible development does not adequately recognize the significance of social context issues to responsible development. (e) Therefore, the National Nanotechnology Initiative is not yet comprehensive and needs to be expanded with respect to identifying and addressing social context issues.

Nanotechnology is a field that we often hear of its name nowadays. Altough what we know about it is soo poor, we admire this field of technlogy, moreover some societies even argues that nanotechnology will cause second endustrial revolution. In addition, nanotechnology makes our basic scientific knowledge upside down and is soo powerfull that it is potent in nearly every scientific field. Thereby, it is imposible to say that nanotechnology; which is soo effective on human and human life; will not cause social and ethical outcomes. In general, the definition of nanotechnology is the reconfiguration of nanomaterials by human; there also are different definitions according to the history of nanotechnology and different point of views. First of all, in comparison to the other tehnology fields, what is the cause of excellence of nanotechnology, what human can do is to foresee the advantages and disadvantages of it, what are the roles of developed and developping countries for the progression of nanotechnology, what is the attitude of nanoethics and what is view of global politics to nanotechological research according to international regulations are all the focus of interests of this study. Last but not least, our apprehension capacity of nanotechnology, our style of adoption and evaluation of it and the way that how we locate nanotechnology in our lifes and ethical values are the other focus of interests.

Nanotechnology drew considerable R&D and research policy attention during the last decade from both developed and emerging developing countries. Nanotechnology is an emerging field where scientists and engineers manipulate matter at the molecular level to create new materials with favourable physical and chemical properties; it is widely acknowledged as a revolutionary technology that will bring path-breaking benefits and profound transformation to human life. Among these developing countries, China has recently emerged as one of the leaders in nanotechnology research. What characterises China's nanotechnology research? Is it different than the nanotechnology research in developed countries? What are the main players and determining factors behind China's fast growth in nanotechnology research? These are the research questions that this article intends to answer.
