Nanoparticle “barcodes” help track cancer drug efficacy

Researchers from Technion Institute of Technology in Israel reported on a method of tagging cancer drugs with “barcodes” to monitor tumor growth. The team detailed their methods in a study published in the November issue of Nature Communications.

The nanoparticle drug delivery system are tagged with synthetic DNA, which act as barcodes used to track the tumor’s response to medication. The drugs are loaded into the nanoparticles, which travel through the circulatory system and stick to tumor cells.
