(PhysOrg.com) -- While current cigarettes are made with a filter created from cellulose acetate which absorbs things like nicotine, tar, and polycyclic aromatic hydrocarbons, Chinese researchers have discovered that nanomaterials from titanium dioxide (TiO2) can be used to reduce the harmful chemicals. For many years, researchers have been looking at adding nanomaterials to current cigarette filters and have tried carbon nanotubes and mesoporous silica. These have worked well; however, they are expensive and like are known about possible health risks.
