ABSTRACT
Debido a la creciente producción y uso de nanomateriales para actividades de investigación y desarrollo en Colombia, es necesario establecer una definición del término nanomaterial que facilite la toma de decisiones en torno a iniciativas de carácter regulatorio y de normatividad. Se presenta la definición de nanomateriales para Colombia que ha adoptado el Consejo Nacional Asesor de Nanociencia y Nanotecnología adscrito a la Red Colombiana de Nanociencia y Nanotecnología.
Due to the increasing production and use of nanomaterials in research and development activities in Colombia, it is necessary to define the nanomaterial term in order to facilitate decision-making process regarding initiatives with a regulatory or normative character. This article presents the nanomaterials definition that has been adopted by the National Advisory Council for Nanoscience and Nanotechnology, a Colombian Network of Nanoscience and Nanotechnology.
Dada a crescente produção e utilização de nanomateriais para a pesquisa e desenvolvimiento na Colombia, é urgente estabelecer uma definição do termo de nanomaterial para facilitar a tomada de decisão sobre iniciativas na regulamentação e as leis. É apresentada uma definição de nanomateriais para a Colombia que aprovou o Conselho Consultivo Nacional de Nanociência e Nanotecnologia ligado à Rede Colombiana de Nanociência e Nanotecnologia.
ABSTRACT
At the present time, nanotechnology is involved in every aspect of scientific life and its applications are being integrated into the economy, industry, trade and medicine. The world will require a skilled work force of more than two million nanotechnologists by 2015. The rapid advance in all fields of nanotechnology has led to integrate nanotechnology courses in high schools, institutes and university curricula all over the world. However, nanotechnology has not as, yet been integrated within the Libyan curricula at any level. Thus, this study focuses and explores the awareness of the academic staff and students in Tripoli (Alfateh) University about nanotechnology and nanoscience. Moreover their readiness to integrate the basics and applications into Libyan education curricula. The results show that education level and work place have an effect on the knowledge of the participants on nanotechnology, where about 65% of PhD degree holders knew about nanotechnology and were keen to learn and integrate this technology in the education system. Around 40 % of the participants’ information about Nanotechnology were gained from the internet while only 17% had obtained information from their own readings. The majority of the participants (60%) supported the idea of introducing nanotechnology studies to the curricula at pre-graduate stage. However, 29% believed that it should be integrated only in postgraduate studies, and only a few of the participants (11.3%) advised that a continuing education program would be the proper way to study nanotechnology. This study showed that relatively little awareness about nanotechnology is seen among Libyan staff members and students. However, the majority of the participants have realized the importance of the field of nanotechnology and its application, and were eager to learn more about this advanced technology. Based on the preliminary study regarding the opinion and readiness of participants of the current study, it is believed that the integration of nanotechnology and nanosciences in Libyan curricula at different levels of education is an inevitable step to meet the very rapid advances in the field of nanotechnology and its applications.
ABSTRACT
One of the most exciting fields of current research is nanomedicine, but its definition and landscape remains elusive due to its continuous expansion in all directions and thus constantly eroding its boundaries and defying definitions. This lack of conceptual framework and confusing definitions was a hurdle for policy makers to enunciate credible goals and allocate resources for the advancement of the field. In this mini review, we have provided a broad framework of nanomedicine which defines its elusive landscape, and we hope this framework will accommodate its explosive growth in the future. Also, we have highlighted the role and scope of atomic force microscopy techniques in the advancement of nanomedicine. For improving health care of all that eventually would require successful intervention at fundamental biological processes, the importance of understanding the structure-function relationship of biomolecules cannot be over emphasized. In this context, AFM and its variants play a pivotal role in contributing towards the nanomedicine knowledge-base that is required for fruitful developments in nano-diagnostics and nano-therapeutics.
ABSTRACT
Molecular nanotechnology has been defined as the three-dimensional positional control of molecular structure to create materials and devices to molecular precision. The human body is comprised of molecules; hence the availability of molecular nanotechnology will permit dramatic progress in human medical services. More than just an extension of "molecular medicine," nanomedicine will employ molecular machine systems to address medical problems, and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine will have extraordinary and far-reaching implications for the medical profession, for the definition of disease, for the diagnosis and treatment of medical conditions including aging, and ultimately for the improvement and extension of natural human biological structure and function. Nanomedicine is the preservation and improvement of human health using molecular tools and molecular knowledge of the human body. Nanomedicines are an emerging group of therapeutics that take advantage of our understanding of phenomena on the nanometer scale. Nanomedicines research requires expertise in a range of diverse fields and thus requires multidisciplinary teams. This article presents a brief review of Nanomedicines with an emphasis on its various aspects associated i.e. introduction, definition, medical and clinical uses, especially role of nanomedicines in treatment of dreadful disease like cancer in current scenario. The article also reveals the concept of nanorobots as well as implications for nanotoxicology from nanomedicines.
