Novel microneedle bandage could save lives by stopping blood loss from wounds

A soldier suffers a serious gunshot wound on a remote battlefield or a machinist has a work accident and gets stuck in traffic on the way to the hospital. Secondary, uncontrolled bleeding from traumatic injury is a leading cause of death for Americans ages one to 46. Chemical and biomedical engineers plan to change that with a novel microneedle patch that can immediately stop bleeding after injury. Source: Penn State/Science Daily
