Personalized bioengineering is a research field and methodological approach focused on the design, development, and application of biological and technological solutions tailored to the unique biological, genetic, environmental, and lifestyle characteristics of individual patients. This interdisciplinary field integrates principles from biology, engineering, and computational science to investigate the relationship between individual physiological profiles and the requirements for bespoke bioengineered interventions, moving beyond standardized approaches. Its significance lies in enabling the creation of more effective, safer, and specific therapies and devices, thereby advancing personalized medicine and improving individual health outcomes.
