Drug Delivery

Drug Delivery refers to the integration of affinity-based targeting strategies with nanotechnology platforms to deliver therapeutic drugs specifically to desired cells or tissues. This approach utilizes engineered nanoparticles functionalized with specific affinity ligands to recognize, bind, and deliver drug payloads with high precision, enhancing therapeutic efficacy while minimizing off-target effects and systemic toxicity.

Technical Content and Mechanism

• Nanoparticle Design for Drug Delivery:
  • Material Selection:
    Nanocarriers can be synthesized from biodegradable polymers (e.g., PLGA, chitosan), lipids (liposomes, solid lipid nanoparticles), dendrimers, or inorganic materials (gold, silica). Selection depends on factors such as drug compatibility, release profile, biocompatibility, and stability.
• Affinity Functionalization:
• • Optimization of Ligand Presentation:
    The density and spatial arrangement of ligands on the nanoparticle surface are optimized to maximize binding avidity without steric hindrance, promoting efficient receptor-mediated binding and uptake by the target cells.
• Drug Loading and Protection:
  • Encapsulation or Conjugation:
    The therapeutic drug can be encapsulated within the core of the nanoparticle, embedded within a polymer matrix, or attached to the surface, depending on the physicochemical properties of the drug and desired release profile.

Applications

• Inflammatory Diseases:
  Targeted delivery of anti-inflammatory drugs to specific immune cell populations or inflamed tissues can improve treatment effectiveness and reduce systemic side effects.
• Central Nervous System (CNS) Disorders:
  Nanocarriers designed to cross the blood–brain barrier via receptor-mediated transport or carrier-mediated mechanisms can deliver neurotherapeutics to treat conditions such as Alzheimer’s disease, Parkinson’s disease, or brain tumors.
• Infectious Diseases:
  By targeting pathogens or infected cells with specific ligands, these nanocarriers can deliver antibiotics or antiviral drugs more effectively, reducing the required dosage and limiting resistance development.
