The use of a tissue adhesive for surgical procedures has prompted a large number of clinical and experimental studies. Alkyl-2-cyanoacrylate esters constitute a family of adhesives with good mechanical properties but their biological compatibility has to be assessed. In this study the cytotoxicity of three commercially available cyanoacrylates and one of unknown composition has been determined. The first part of the study deals with direct contact testing procedures using L 929 cells challenged with drops of adhesives: cell morphology, cell growth and bacterial growth inhibition were assayed. Testing methods included cell viability assay using vital dyes, cell growth measurement using crystal violet staining uptake and bacterial growth assay using S. aureus growth inhibition. All the cyanoacrylate adhesives tested were found to be cytotoxic and to inhibit cell proliferation: differences between the cyanoacrylates were found.
