Researchers aim to achieve Paul Ehrlich's "magic bullet" concept for targeted drug delivery. Engineering principles may enable smart therapeutic agents with propulsion, navigation, and homing capabilities for precise delivery.

Area of Science:

  • Biomedical Engineering
  • Pharmacology
  • Drug Delivery Systems

Background:

  • The "magic bullet" concept, proposed by Paul Ehrlich, seeks targeted therapeutic agents to maximize efficacy and minimize off-target effects.
  • Current drug delivery methods achieve only a few percent of the administered dose at the intended target sites.
  • Existing delivery systems primarily rely on physical and biochemical properties, lacking precise targeting capabilities.

Purpose of the Study:

  • To explore the application of engineering principles to develop advanced therapeutic delivery systems.
  • To conceptualize smart therapeutic agents with integrated propulsion, navigation, and homing functionalities.
  • To overcome the limitations of current drug delivery systems in achieving precise in-vivo targeting.
