: Combining two different drugs (e.g., a chemotherapeutic and a gene-silencing agent) within a single nanoparticle to overcome multi-drug resistance.

: Nanomaterials that combine a therapeutic agent with a diagnostic imaging agent, allowing doctors to track the drug's location and effectiveness in real-time.

: Combining organic (lipids/polymers) and inorganic (gold/silica) materials to create "smart" formulations that respond to external stimuli like heat or pH levels. 4. Applications and Routes of Administration

: Using lipid-based nanoparticles to help large molecules survive the digestive tract.

: Many new drug candidates are poorly water-soluble. Nano-formulations increase the surface area, significantly improving dissolution rates.

Nanobiomaterials have revolutionized galenic formulations (the art of preparing and compounding medicines) by enhancing the stability, solubility, and targeted delivery of active pharmaceutical ingredients.
