The heightened focus in medical research on nanotechnologies is reflected by the number
18、 of medical and related scientific journals that are reporting on this research. The number of publications mentioning both nanotechnology and biology or medicine has increased logarithmically since approximately the year 2000. 1 This Technical Report explains current concepts related to human healt
19、hcare in the clinical setting and identifies pertinent and timely categories most likely to be advanced by nanotechnologies. Certain aspects of human healthcare are expected to be advanced by nanotechnologies more than others, and standardization needs unique vocabulary to support the development of
20、 applications of nanotechnologies within it. It is recognized, for example, that physical chemists use the term “substrate” to describe a material surface supporting adsorption processes; this differs from a biologists use of the term “substrate” to describe a substance that an enzyme acts upon. Due
21、 to the keen public interest in the advancement of human healthcare, a common vocabulary is particularly relevant to the development of research proposals to gain funding and to communicate findings and results. This Technical Report provides a taxonomic framework to serve as the basis for the devel
22、opment of terminology related to the application of nanotechnologies in human healthcare. The framework identifies categories associated with the clinical value chain most likely to be advanced by nanotechnologies and describes some of the promising technologies being developed and utilized within t
23、he clinical workflow. It is intended that terms will be identified and harmonized definitions will be developed for them within the framework offered by this Technical Report. ISO 2015 All rights reserved v PD ISO/TR 17302:2015 Nanotechnologies Framework for identifying vocabulary development for na
24、notechnology applications in human healthcare 1 Scope This Technical Report will not attempt a formal, comprehensive definition of “nanomedicine”. Instead, it will provide a taxonomic framework for the development of vocabulary for clinical applications of nanotechnologies in human healthcare. While
25、 it is understood that the origins of nanotechnologies for healthcare applications emerge from pre-clinical and translational research, the interest of this Technical Report is to determine where these technologies will impact the clinical value chain and the practice of medicine. This Technical Rep
26、ort is intended to facilitate communications between developers and users of nanotechnologies, deliverers and users of medicine including the pharmaceutical, research and medical communities, regulatory professionals, and additional organizations and individuals who might interact with these groups,
27、 including biotechnology, diagnostic, and medical device companies, the life sciences, patent attorneys and patent offices, institutional review boards, ethics review boards, and accreditation organizations. 2 Symbols and abbreviated terms nm nanometer 3 Framework 3.1 General The term “nanomedicine”
28、 is used by the scientific community and government agencies to describe a field that is relatively undefined in terms of the affected health care segments and the specific advances in nanotechnologies for biomedical applications. In addition, the relevant mechanisms currently associated with diagno
29、sis and treatment in biological processes can be larger than approximately 100 nm (e.g. endocytosis). Several participants from the biological sciences work with 400 nm diameter particles as drug carriers, while others consider 1 000 nm or 500 nm as pertinent in exploring emerging applications. Over
30、all, the products currently enabled by nanotechnologies that are available for commercial clinical use are characterized by in vitro bulk properties or systemic effects.

32、oiety Figure 1 Examples of nanosize objects of interest in healthcare applications 2 In contrast, the current ISO definition of the term “nanoscale” stems from materials science and expresses in part the size range associated with quantum effects. The broad, enabling nature of nanotechnologies means
33、 that convergence with the biological sciences will continue to intensify. However, this Technical Report does not seek to suggest that current definitions in nanotechnologies, such as the approximately 100 nm upper boundary found in the ISO definition of the term “nanoscale”, 3be normalized to acco
34、unt for all size relationships in biological systems. 3.2 The clinical value chain 3.2.1 General In recognition of the advancements that are anticipated in the clinical practice of medicine associated with nanotechnologies, relevant applications of nanotechnologies in human healthcare can be identif
35、ied by their location in the clinical value chain (see Figure 2). Figure 2 The clinical value chain The clinical value chain suggested for use in this Technical Report consists of 4 segments. The prediction and prevention segment includes nanotechnologies that are used to predict, or prevent 2 ISO 2
36、015 All rights reserved PD ISO/TR 17302:2015 ISO/TR 17302:2015(E) disease, conduct disease screening, and which are used in disease surveillance. The diagnosis segment includes nanotechnologies that are used for in vitro and in vivo detection, classification, grading, etc. of disease. The therapy se
37、gment includes nanotechnologies that are associated with therapy for disease. This includes drugs and other medicines (e.g. biopharmaceuticals), surgical implants, materials, devices, and surgical aids, and alternative therapies (e.g. stem cells). The monitoring segment includes nanotechnologies tha
38、t are used to monitor disease after therapy to evaluate the efficacy of treatment and the progression or remission of disease, recurrence, side effects, etc. Underlying these segments are pre-clinical and translational activities. That is, fundamental nanotechnology developments in academia, life sc
39、ience, and the biopharmaceutical industry are undertaken with the objective of having an eventual impact or application in one or more of the clinical value chain segments. These might be nanotechnologies used to understand basic life processes or nanotechnologies that support products used in a cli
40、nical setting (see Figure 3). Figure 3 Illustrative example of the general stages of development for nanotechnologies used in medicine, which highlights the European Unions approach 4 3.2.2 Prediction and prevention Prediction and prevention inlcudes technologies that permit accurate screening to id
41、entify the risk or susceptibility to disease or disease recurrence, prognosis based on one or more indicators, public health surveillance of disease and immunization to prevent disease. Products enabled by nanotechnologies in this value chain segment include sprays, coatings, antiseptics and vaccine
42、s. Two application areas that are useful to highlight the contribution of nanotechnologies to this segment of the clinical value are the prevention of surgical site infections and the use of informatics to predict and reduce drug side effects by identifying patients at risk. Surgical site infections
43、 encompass inadvertent infections occurring inside the hospital or physicians office, the prevention of which can include the use of disinfectants, sterile surfaces, protective gowns, air handling, and appropriate waste disposal. The use of nanotechnologies for preventing adventitious infections mig
44、ht be the source of new terms, e.g. “nanotextured surface” to describe a product designed by the coating industry to ensure a sterile environment. Bioinformatics and nano-informatics might be used to evaluate disease prevalence, drug design, acceptable test protocols, dose metrics, and toxicity. ISO

Nanotechnologies can be used to advance sensing systems to improve the accurate and early detection and diagnosis of disea

There are multiple components in the diagnostic process ranging from the manufacturing setting (e.g. reagent and detection systems) to the selection of target analytes (e.g. cells, proteins, tissue structures) and the organism setting (in vitro/ex vivo or in vivo) (see Figure 4).
