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…
