Argonne Researches Medical Inhalers (IMAGE) DOE/Argonne National Laboratory Caption Argonne researcher Alan Kastengren, left, and principal investigator Dan Duke, work with spray inhalers at an Advanced Photon Source beamline. The researchers have teamed with scientists in Australia and Italy to study the complex inner workings of spray inhalers, using techniques developed for investigation of engine fuel injectors. Duke and Kastengren hope the knowledge gained from the project will lead to improved inhalers that can be used with a wider variety of drugs.
