Nanomaterials for medicine
(John Wiley & Sons, 2016-03-11) Güler, Mustafa O.; Tekinay, Ayşe B.; Güler, Mustafa O.; Tekinay, Ayşe B.
Nanomaterials with controlled physical, chemical, and biological characteristics can be used for the therapy of the specific causes of the diseases. There are several ways to develop new materials in nanometer scale. Mainly, top‐down and bottom‐up approaches are the two major techniques to produce nanomaterials. Depending on the application area, either one or both of these approaches can be used to develop materials that can be used in studying pathophysiology of diseases and their diagnosis and therapy. Especially, bioinspired and biomimetic strategies yield products that can replace or accommodate activities of the natural biomolecules. Nevertheless, for effective diagnosis and therapy of diseases, it is almost crucial to first understand the molecular reasons behind disease development. The nanomaterials can be also used in regenerative medicine applications. Although there have been extensive advances in developing nanomaterials for biomedical purposes, only few of them have been translated into clinics.

Privacy in the genomic era
(Association for Computing Machinery, 2015) Naveed, M.; Ayday, E.; Clayton, E.W.; Fellay J.; Gunter, C.A.; Hubaux J.-P.; Malin, B.A.; Wang, X.
Genome sequencing technology has advanced at a rapid pace and it is now possible to generate highlydetailed genotypes inexpensively. The collection and analysis of such data has the potential to support various applications, including personalized medical services. While the benefits of the genomics revolution are trumpeted by the biomedical community, the increased availability of such data has major implications for personal privacy; notably because the genome has certain essential features, which include (but are not limited to) (i) an association with traits and certain diseases, (ii) identification capability (e.g., forensics), and (iii) revelation of family relationships. Moreover, direct-to-consumer DNA testing increases the likelihood that genome data will be made available in less regulated environments, such as the Internet and for-profit companies. The problem of genome data privacy thus resides at the crossroads of computer science, medicine, and public policy. While the computer scientists have addressed data privacy for various data types, there has been less attention dedicated to genomic data. Thus, the goal of this paper is to provide a systematization of knowledge for the computer science community. In doing so, we address some of the (sometimes erroneous) beliefs of this field and we report on a survey we conducted about genome data privacy with biomedical specialists. Then, after characterizing the genome privacy problem, we review the state-of-the-art regarding privacy attacks on genomic data and strategies for mitigating such attacks, as well as contextualizing these attacks from the perspective of medicine and public policy. This paper concludes with an enumeration of the challenges for genome data privacy and presents a framework to systematize the analysis of threats and the design of countermeasures as the field moves forward. © 2015 ACM 0360-0300/2015/08-ART6 $15.00.
