The Washington Life Sciences Discovery Fund said today it has given out four grants worth a combined $600,000. Jane Burns of Seattle Children’s Hospital, along with Maple Valley, WA-based Enertechnix, will use their grant money to work on an air sampling technology to spot lung infections, while University of Washington researcher Patrick Stayton will work on creating faster immunoassays for cancer and heart disease. Christopher Bernards of Benaroya Research Institute will test a device developed by Seattle-based Impel Neuropharma to deliver neurological drugs more effectively into the brain, while UW’s Barry Lutz will study ways to reduce intracranial pressure in patients suffering from brain trauma or disorders.
