Biocompatible magnetic fluids are applied for medical diagnosis and therapy. In this work, magnetic particles were prepared and then were coated with various 2nd surfactants for obtaining the water‐based magnetic fluids by chemical coprecipitation. Toxicity of each fluid sample was estimated using Sprague–Dawley rats. Finally, the used samples resulted in severe toxic reactions through in vitro, indicating that all samples can not be seen as biocompatible agents or suggesting the possibilities of another effects.
