Questions and Answers

What is the primary purpose of the reticuloendothelial system (RES)?

To induce aggregation of intravenously administered nanomedicines

To produce nanoparticle stabilization through electrostatic forces

To facilitate the absorption of drugs through the gastrointestinal tract

To remove immune complexes from the circulation (correct)

Which of the following is NOT a route of parenteral administration?

Subcutaneous (SC or SQ)

Intramuscular (IM)

Oral (correct)

Intravenous (IV)

What is the primary mechanism by which nonionic surfactants or polymers provide steric stabilization to nanoparticles?

By facilitating the absorption of the nanoparticles through the gastrointestinal tract

By inducing aggregation of the nanoparticles in the high ionic strength environment of the blood

By adsorbing onto the particle surface and producing strong repulsion between particles (correct)

By creating a high surface charge density that induces repulsion between particles
