Russian chemists have developed a unique transforming nanoparticle that can help fight cancer and other diseases. Professor Ekaterina Skorb and her team from ITMO University in St. Petersburg created hollow nanoparticles with a covering of polymer filaments and granules of titanium oxide and silver the Sputnik reported on Friday. When illuminated with an infrared laser the structure of the nanoparticle collapses from heat and oxygen which releases the particle's contents. In the study published in the journal Bioconjugate Chemistry the team tested out their nanoparticles on bacteria whose DNA was modified to glow when molecules came into contact with artificial
