The battle against cancer is being fought on many fronts. Among the most cutting-edge research efforts are attempts to engineer nanotechnology-based therapies. To aid in this endeavor, the Nanotechnology Characterization Laboratory, part of the National Cancer Institute’s Alliance for Nanotechnology in Cancer and the National Cancer Institute at Frederick, has developed methods for nanoparticle…, E2524, , Test Method for Analysis of Hemolytic Properties of Nanoparticles, -E2524 is a protocol for examining the destruction of red blood cells (hemolysis) that can lead to anemia, jaundice and other issues. All intravenously administered drugs must be examined to determine potential for hemolysis. • , E2525, , Test Method for Evaluation of the Effect of Nanoparticulate Materials on the Formation of Mouse Granulocyte-Macrophage Colonies, -E2525 describes a method for evaluating nanoparticle stimulation or inhibition of the maturation of certain bone marrow cells (macrophages). A common side effect of anti-cancer drugs is inhibition of this process, and bone marrow cells may be particularly sensitive to nano-scale material. • , E2526, , Test Method for Evaluation of Cytotoxicity of Nanoparticulate Materials on Porcine Kidney Cells and Human Hepatocarcinoma Cells, -Because studies have indicated that many nanoparticles are cleared from the body through the kidney or liver, these organs are good choices for target organ toxicity evaluation. E2526 presents a method for evaluation of nanomaterial toxicity by examining effects on kidney and cancerous liver cells. Martin Fritts is senior principal scientist at the Nanotechnology Characterization Laboratory and…

Although ASTM International Committee E56 on Nanotechnology was just established this year, it has already begun an ambitious program of developing new standards. Committee E56 is currently developing the following proposed standards, which deal with environmental safety issues, hemolytic properties and particle size measurement. Interested parties are invited to participate in the development of…, WK8985, Guide for Handling Unbound Engineered Nanoparticles in Occupational Settings, Academic, government and industrial laboratories are currently performing nanotechnology research and development and the scope and breadth of this work is expected to grow dramatically. Manufacturing processes involving nanomaterials have begun and commercially available nano-based products have been introduced. All of this activity in the nanotechnology realm has created the need for the…, WK8997, Practice for Analysis of Hemolytic Properties of Nanoparticles, Subcommittee E56.02 on Characterization has begun working on proposed new standard WK8997, Practice for Analysis of Hemolytic Properties of Nanoparticles. This proposed standard would provide a suitable procedure for establishing the safety of nanoparticulate materials that will be used in vivo , such as nanoparticles for therapeutics and diagnostics. "Nanotechnology products will be used in…, For further technical information, contact Scott McNeil, director, Nanotechnology Characterization Laboratory, Frederick, Md. (phone: 301/846-6939; mcneils@ncifcrf.gov )., WK8705, Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), Subcommittee E56.02 was formed to answer questions regarding characterization, such as size and shape of materials. Another proposed new standard under the jurisdiction of Subcommittee E56.02 is WK8705, Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), which deals with the vital issue of size characterization. The purpose of the…
