Air pollution is a major environmental risk to human health, and air quality has become an increasing concern in the industrialized world. Rapid and accurate detection and characterization of airborne particulates is crucial for monitoring and improving air quality. In this proposal, we develop a compact, cost-effective, computational lens-free holography platform for high-throughput characterization of […]

Fine particulate air pollution is recognized as causing health problems globally, but health researchers are just starting to understand where people receive their exposure, which will influence policies and regulations. There is a need for size-resolved particle measurements using a device that can be carried easily by a person. Nanozen has built such a device, […]
