Bioactivity refers to the ability of a substance to exert a specific biological effect on a living organism. This term is commonly used in research areas such as pharmacology, biotechnology, and biomedical science to evaluate the effectiveness of compounds or materials in influencing biological processes or systems. Bioactivity can include a wide range of effects, such as stimulating cell growth, inhibiting enzyme activity, or inducing a specific physiological response in an organism. Researchers often study bioactivity to identify potential therapeutic agents, understand disease mechanisms, or develop new treatments for various health conditions.
