Frequently Asked Questions (FAQ)

Nanomedicines General Questions

1. What are nanomedicines?

Nanomedicines are pharmaceutical formulations containing nanosized components designed for diagnosis, treatment, or prevention of diseases. These nanosized materials offer unique properties and functionalities not found in bulk materials.

2. What are the advantages of nanoparticle drug delivery systems?

Nanoparticle drug delivery systems offer several advantages, including targeted delivery to specific tissues or cells, improved bioavailability of drugs, reduced side effects, prolonged circulation time in the body, and the potential for combination therapy

3. How do nanoparticles facilitate targeted drug delivery?

Nanoparticles can be engineered to target specific tissues or cells by attaching ligands or antibodies that recognize molecular markers on the surface of target cells. This ensures precise delivery of therapeutic agents, minimizing damage to healthy tissues.

4. What types of nanoparticles are commonly used in drug delivery systems?

Common nanoparticles include liposomes, polymeric nanoparticles, dendrimers, and metallic nanoparticles such as gold and silver nanoparticles. Each type offers unique characteristics suitable for different therapeutic applications

5. How do nanoparticles improve drug bioavailability?

Nanoparticles can protect drugs from degradation and clearance in the body, allowing for prolonged circulation and enhanced absorption at the target site. This improves the drug's bioavailability and therapeutic efficacy

6. What are some challenges associated with nanoparticle drug delivery systems?

Challenges include potential toxicity of nanoparticles, difficulty in scaling up production, controlling particle size and distribution, achieving sufficient drug loading, and ensuring stability and reproducibility of formulations
