SUPPLEMENTARY INFORMATION:

I. Background

    Nanomaterials, measured in nanometers (a billionth of a meter), 
often possess physical and chemical properties that are different from 
their larger counterparts. Due to the high surface area to volume 
ratio, the small size, and the type of nanoscale material, these 
materials may exhibit altered magnetic, electrical, optical properties 
and altered chemical and biological activities. These characteristics 
provide the potential for nanomaterials to be used in a variety of 
medical device applications. However, some of these nanomaterial 
properties may also present safety concerns that are not found in their 
larger counterparts. The use of nanotechnology is increasingly 
applicable and provides novel opportunities in medical device 
development. The scientific hurdles (e.g., biocompatibility and 
toxicity) for safe use of nanomaterials in medical devices, including 
the processes and standards for their manufacture and characterization, 
are not understood.
    In July 2007, FDA's Nanotechnology Task Force issued a report 
describing the state of the science and regulatory challenges in 
translating nanotechnology into FDA-regulated products (available at 
http://www.fda.gov/ScienceResearch/SpecialTopics/Nanotechnology/
NanotechnologyTaskForceReport2007/default.htm). A general finding of 
the report is that nanoscale materials

[[Page 51830]]

present regulatory challenges similar to those posed by products using 
other emerging technologies and that these challenges may be magnified 
because nanotechnology can be used in, or used to make, any FDA-
regulated product. In addition, the properties of a material with 
features in the nanoscale range might change, impacting the safety and 
effectiveness of the FDA-regulated products.
    The objective of this public workshop is to obtain information on 
manufacturing, characterization, and evaluation of biocompatibility of 
medical devices containing or utilizing nanomaterials and 
nanostructures.

II. Public Participation

    There are two types of opportunities for participation planned for 
the public workshop: Time limited oral presentations and round-table 
discussions.
    If you wish to make an oral presentation during the public 
workshop, you must indicate this at the time of registration. The 
number of presentations may be limited based on the number of requests 
received during the public comment period. When registering, you will 
be required to identify the title of the topic you wish to address in 
your presentation and answer all the related questions on the 
registration form at http://www.fda.gov/MedicalDevices/NewsEvents/
WorkshopsConferences/default.htm. FDA will do its best to accommodate 
requests to present and will focus discussion to the topics described 
in this document (see section III of this document). Individuals and 
organizations with common interests are urged to consolidate or 
coordinate their presentations, and to request time for joint 
presentations. FDA will determine the amount of time allotted to each 
presenter and the approximate time that each oral presentation is to 
begin.
    To close each of the two sessions, FDA will hold a round-table 
discussion between FDA staff and selected participants representing a 
range of constituencies. If you wish to be a participant in round-table 
discussions, you must indicate this interest at the time of 
registration, and also submit a brief statement that describes your 
experience or expertise with nanotechnology. FDA will attempt to have a 
range of constituencies represented in this discussion group. Others in 
attendance at the workshop will have an opportunity to listen during 
each round-table discussion and provide public comments, time 
permitting. FDA will determine the participants based on the requests 
received. The participants in each round-table discussion will remark 
on the presentations given during the session, engage in a dialogue 
with each other and FDA staff, and provide closing thoughts on the 
session. Round-table participants will not be asked to develop 
consensus opinions during the discussion, but rather to provide their 
individual perspectives.

III. Issues for Discussion

    The workshop will focus on two topics: (1) Manufacturing and 
characterization of medical devices containing or utilizing 
nanomaterials or nanostructures; (2) biocompatibility evaluation of 
medical devices containing or utilizing nanomaterials or 
nanostructures. The discussion on manufacturing and characterization 
will include the evaluation of physico-chemical properties of 
nanomaterials or nanostructures, characterization methods required, 
device manufacturing processes and evaluation of the final processed 
device after sterilization, and stability and aging studies. The 
discussion on biocompatibility evaluation will include testing for 
potential release of nanomaterials and additional testing 
considerations other than standard testing methods to determine the 
biocompatibility and toxicity of devices containing or utilizing 
nanomaterials or structures. For further information, please refer to 
the meeting registration Web page at http://www.fda.gov/MedicalDevices/
NewsEvents/WorkshopsConferences/default.htm.
