Purpose of the Study:
- To discuss the application of colloidal, particulate carrier systems (25 nm to 1 micrometer) in drug delivery.
- To highlight carrier systems with diminished uptake by mononuclear phagocytes.
- To consider specific targeting strategies for carriers to particular tissues or cells.
Main Methods:
- Review of colloidal drug carrier systems (liposomes, nanoparticles).
- Analysis of carrier design principles for targeted delivery.
- Discussion of systems exhibiting reduced mononuclear phagocyte uptake.
Main Results:
