It has become an important component of modern healthcare systems.

57.                       Smart Therapeutics
Smart therapeutics are advanced treatment systems capable of responding to specific biological signals. They deliver therapy only when and where it is needed. Smart therapeutics improve treatment precision and reduce side effects. Examples include responsive drug delivery systems. They represent an important future direction in medicine.

58.                       Predictive Medicine
Predictive medicine uses genetic, molecular, and clinical information to forecast disease risk. Early prediction enables preventive interventions before symptoms develop. Predictive approaches improve long-term health outcomes. They support proactive rather than reactive healthcare. Predictive medicine is a major goal of precision medicine.

59.                       Preventive Medicine
Preventive medicine focuses on preventing disease and promoting health before illness occurs. Molecular technologies help identify individuals at increased risk. Preventive strategies include screening, vaccination, and lifestyle modification. Early intervention reduces disease burden and healthcare costs. Prevention is a key pillar of future healthcare.

60.                       Future Healthcare Systems
Future healthcare systems will integrate genomics, artificial intelligence, digital health, and precision medicine. These systems will emphasize personalized, predictive, preventive, and participatory care. Advanced technologies will improve diagnostic accuracy and treatment effectiveness. Healthcare delivery will become more data-driven and patient-centered. Future molecular medicine will transform global health outcomes.
