2 NCL provides infrastructure support to the Alliance and to nanotech researchers - to overcome obstacles and translate ‘nano’ into the clinical realm. NCL Objectives –Characterize nanoparticles using standardized methods –Conduct structure activity relationships studies –Facilitate regulatory review of nanotech constructs –Engage in educational and knowledge sharing efforts The NCL is a national resource available to investigators from academia, industry and government NCI Cancer Nanotechnology Plan ncl@ncifcrf.gov http://ncl.cancer.gov

9 Develop Protocols Protocols are developed and validated at the NCL. Intent is to leverage existing methods and/or Standards when possible. Submit Draft Standard Draft of Standard is submitted to ASTM E-56.20 Subcommittee for comment and revision STANDARD E5620-06 Ballot of Standard is submitted to ASTM members for consensus. Consensus Ballot Solicit Comments on Protocol Protocols are submitted to partners and collaborators for comment and revision. NCI FDA NIST Voluntary Consensus Standard (VCS) is established. Industry, Academia, Government VCS informs regulatory agencies and promotes commercialization of nanotechnology for medical applications NCL Method ITA-1 Analysis of Hemolytic Properties of Nanoparticles Nanotechnology Characterization laboratory National Cancer Institute at Frederick SAIC-Frederick Frederick, MD 21702 (301)-846-6939 Voluntary Consensus Standards
10
10 First voluntary consensus standards for biocompatibility- testing of nanomaterials intended for medical applications E2524 (hemolysis), E2525 (CFU-GM inhibition), E2526 (kidney and liver cytotox) ASTM Standards RMs NCI supported the production of NIST’s colloidal gold RM. –Au selected for calibration and biocompatibility 10nm, 30nm, and 60 nm diameters Available as of January ’08 Standard Reference Materials Standard Methods Interlaboratory Comparison ASTM ILS 166 Standards Development

11 Data Dissemination http://ncl.cancer.gov Conferences and Working Groups Newsletters Manuscripts and Book Chapters Formal Reports
12
12 Data Dissemination CaNanoLab provides storage and retrieval of nanoparticle characterizations for data sharing in support of NCL’s educational and knowledge sharing efforts.
13
13 Informatics & Science –Data management (storage and retrieval) –Data sharing –Comparison of multiple results (e.g. size and toxicity) –Provide the necessary input into Structure Activity Relationship (SAR) modeling and simulation tools
