Lipid based nanoparticles to deliver molecules to the tumors

lipid polymer based nanoparticles

Early phase Northwestern Medicine research has demonstrated a potential new therapeutic strategy for treating deadly glioblastoma brain tumors. The strategy involves using lipid polymer based nanoparticles to deliver molecules to the tumors, where the molecules shut down key cancer drivers called brain tumor initiating cells (BTICs). “BTICs are malignant brain …
