Cell viability assays are essential experimental methods used to evaluate the viability of cells in response to various test drugs. These assays can be conducted on tissues, cells, or entire organs. The primary objective of assessing cell viability is to identify any unintended inorganic reactions within the cells, which can then be measured to determine their overall viability. This assessment is crucial in all types of cell culture studies and serves as a foundational component in evaluating drug effectiveness and the impact of multiple combined particles on cell health.
