Assessment of nanoparticles' safety: corrected absorbance-based toxicity test.

We developed a method to correct absorbance-based toxicity tests to remove the influence of the deposited dose of nanoparticles. As a model of absorbance-based toxicity tests, we chose the frequently used MTS test. The corrected cell viabilities obtained with the MTS test matched the results of the fluorescence-based PrestoBlue® test.
