Doppler Used in Novel Microbial Assay To Tell a Friend from...

Scientists at Purdue University have developed a unique microbial biodynamic assay based on the Doppler effect. The method uses 3D in vitro tissue cultures as living sentinels to quickly detect dramatic changes metabolic profiles in response to pathogenic bacteria. This new approach can be used to detect the pathogenicity of unknown microbes and determine treatments for antibiotic-resistant bacterial strains.
