AB - Carbon nanotubes (CNTs) have gained substantial interest as a material for biomedical devices with reliable properties suitable for electrically conducting biomedical devices. While CNTs combine ideal properties for a number of tissue-interfacing applications, their biocompatibility and safety have been the source of considerable conjecture. This study outlines a method for evaluating biocompatibility, using a low-cost, short-term assessment model of CNT with primary cells, which are more representative of an in vivo situation than cell lines. It was demonstrated that carboxylate-modified, multi-walled CNTs exhibit cytotoxic behavior in as little as 6 hr of exposure to primary fibroblasts. The resultant cell death was concentration dependent, demonstrating the efficacy of acute assessment of cytocompatibility. Although cell viability remained relatively high (being above 85% for all CNT concentrations up to 500 μg/ml), these results reflect similar relationships found for longer term exposures. This method has reliable potential for high-throughput assessment and quality control of CNTs in biomedical applications using a primary cell model. © 2013 © 2013 Taylor & Francis.
