Water soluble membrane peptide (pHLIP) is conjugated with anionic dendrimer-based paramagnetic nanoparticle. pHLIP-tagged nanoparticles bind to and are internalized by breast cancer cells in vitro. Systemic delivery of dendrimer-based nanoparticles lead to accumulation of the nanoparticles in a flank mouse model of breast cancer that are detected by optical and MR imaging.
