Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Pharmacology

Background:

  • Ideal drug delivery requires precise targeting and minimal side effects.
  • Current therapeutics have limited targeting specificity and face biological barriers.
  • A decoupled approach using targeted vectors is proposed to overcome these limitations.

Purpose of the Study:

  • To introduce a novel drug delivery strategy decoupling therapeutic action from delivery.
  • To explore the potential of nanotechnology-based vectors for targeted drug delivery.
  • To address the limitations of current drug delivery systems in reaching diseased tissues effectively.

Main Methods:

  • Designing drug-carrying vectors with multiple targeting mechanisms.
  • Ensuring vectors are large enough to evade bodily defenses but small enough to avoid vessel blockage.
