Abstract
The disclosure provides compositions comprising peptide-based nanofiber precursors and methods of using the same to inhibit cancerous cell growth and/or to deliver therapeutic or diagnostic agents to cells, e.g., cancerous cells. The compositions of the present technology include peptide-based nanofiber precursors as well as carrier complexes comprising a therapeutic or diagnostic agent, and a peptide-based nanofiber precursor. Also provided herein are methods for delivering a therapeutic or diagnostic agent to a cell comprising contacting the cell with a carrier complex including a therapeutic or diagnostic agent, and a peptide-based nanofiber precursor.
