Preparation, characterization, and cellular associations of silicon logic-embedded vectors

Abstract

Logic-embedded vectors (LEVs) have been introduced as a means to overcome sequential, biological barriers that prevent particle-based drug delivery systems from reaching their targets. In this chapter, we address the challenge of fabricating and optimizing LEVs to reach non-endosomal targets. We describe the general preparation, characterization, and cellular association of porous silicon-based LEVs. A specific example of LEV fabrication from start to finish, along with optimization and troubleshooting information, is presented to serve as a template for future designs.
