Targeting Nanoparticles into Tumors
Modular Approach to Multi- functional Nanoparticles Physically target:
- vascular cells
- tumor cells
- extracellular matrix
Trigger/engineer:
- tissue penetration
- RES avoidance
- subcellular targeting
- diagnostic signal(s)
- release of therapeutic
agent
- amplification of targeting
Isolation of homing peptides by ex vivo/in vivo phage screening
Ex vivo
Wash Rescue phage and amplify Incubate phage with cells from target tissue Rescue and amplify phage from target tissue Repeat in vivo screening, sequence individual phage from enriched pool
In vivo
Inject (enriched) phage library into a mouse iv Phage bind to blood vessels in target tissue
