Biological evaluation is a research area that focuses on assessing the biological activity, toxicity, and potential risks of substances such as drugs, chemicals, and materials on living organisms. This field involves conducting various tests and studies to determine the effects of these substances on cells, tissues, organs, and whole organisms. Biological evaluation plays a crucial role in the development and approval of new pharmaceuticals, chemicals, and biotechnological products, as well as in evaluating the safety and environmental impact of products already on the market. The goal of biological evaluation is to ensure the safety and efficacy of these substances for human and environmental health.
