DigInfo - (http://movie.diginfo.tv) At Nanotech 2008, Nissei Bio in collaboration with Dr. Norio Nishi of Hokkaido University displayed their DNA filter which uses extracted DNA from Salmon milt to create water and air purifiers. Salmon milt is often discarded by fisheries but contains the necessary double stranded DNA used for the construction of the DNA filter. These filters are very good at reducing the amount of intercalating compounds in the air which are very dangerous when inhaled. DNA filters cut down at least twice as much harmful carcinogens as carbon filters and can be used for cigarette filters, air conditioners, air purifiers and masks. Also useful for water purification, DNA filters can reduce the dioxins and heavy metal ions in water.
