The smart targeting of nanoparticles

Area of Science:

• Nanomedicine
• Biotechnology
• Drug Delivery

Background:

• Selective delivery of nanoparticles to diseased tissues remains a significant challenge in nanomedicine.
• The enhanced permeability and retention (EPR) effect is often insufficient or unsuitable for targeting specific pathogenic sites.
• Nanoparticle functionalization via ligand conjugation is a key strategy for achieving targeted delivery.

Purpose of the Study:

• To review methods for ligand-nanoparticle functionalization.
• To provide an overview of various ligand classes used for nanoparticle targeting.
• To discuss emerging and unconventional approaches in nanoparticle targeting.

Main Methods:

• Literature review of nanoparticle functionalization techniques.
• Categorization and analysis of different ligand types (small molecules, peptides, antibodies, engineered proteins, aptamers).
• Exploration of novel and unconventional targeting strategies.

Main Results:

• Detailed illustration of diverse ligand-nanoparticle conjugation methods.
• Comprehensive cross-section of established and novel ligand classes for targeting.
• Discussion of the potential and limitations of various targeting strategies.

Conclusions:

• Ligand-functionalized nanoparticles offer enhanced specificity for targeted delivery in nanomedicine.
• A variety of ligand classes can be employed, each with unique targeting capabilities.
• Ongoing research into unconventional methods promises further advancements in nanoparticle targeting efficiency.
