A nanocapsule of nucleic acids and peptides that releases the medicine inside in response to defined enzymes. (1) in the first step the peptide undergoes cross-linking on the surface of the nanoparticle; (2) In the next step, a defined enzyme recognizes the peptide cross-linking group, (3) and in the last step, the enzyme's release leads to the release of the drug or the nucleic acids that were locked inside the capsule.

Computer simulation of the atomistic model of the particle. It can be seen that the material moved by the diamond needle accumulates at the edge of the particle and creates unique steps, which are later used as "guide rails" that return to the footprint, by diffusion, the material moved to the side. After a time the particle returns to its original shape. Source: Courtesy of the Technion.

Diagram from the article, which presents the innovative method developed: "We pack tiny amounts of the anti-cancer drugs inside dedicated nanoparticles that we developed. The uniqueness of these nanometer packages is that they flow in the bloodstream to the tumor and there are swallowed by the cancer cells. To these packages we attach "In advance, artificial DNA sequences are used as barcode readers of the drug's activity in the cancer cells. After 48 hours, a sample (biopsy) is taken from the tumor, and the barcode analysis provides accurate information on the cells that were destroyed (or not) by each drug."
