IBM researchers and a team in Singapore have taken common plastic and engineered it into a nanomedicine that is 1,000 times smaller than a grain of sand and can be used to attack fungi that are resistant to antibiotics, VentureBeat reported. The new nanomedicine represents a broadening of the technology created in 2011 at the IBM Almaden research center in San Jose, Calif., and at the Institute of Bioengineering and Nanotechnology in Singapore to attack bacteria that have also become resistant to antibiotics. The researchers think they can use the nanomedicine to target only bad cells within a body and kill them like ninja assassins. The breakthrough in anti-fungal treatments could be commercialized over time, and it suggest that a technology that started out as narrow cure could become more broadly useful against infections that affect a billion people a year.
