Delivery Routes & Associated Barriers

Oral: Gastrointestinal stability and absorption.

IV: Opsonization and distribution throughout the circulatory system.

Inhalation and transdermal: Challenges associated with achieving sufficient local delivery.

Nanoparticle Targeting Strategies

The primary goal of nanomedicine is to achieve targeted drug delivery, minimizing off-target effects. This is typically achieved through several strategies:

1. Ligand Conjugation: Nanoparticles are functionalized with ligands – small molecules that specifically bind to receptors on target cells or tissues.

2. Stimuli-Responsive Systems: These systems utilize external stimuli (e.g., pH, temperature, light) to trigger drug release at the desired location.

3. Microenvironment Tuning: Exploiting differences in the local microenvironment – such as tumor hypoxia or inflammation – to enhance nanoparticle accumulation and drug delivery.

Examples

Example: Inhaled Nanoparticle Formulation

Optimize aerodynamic diameter.
