A review on current trends in aerosol pharmaceutical engineering

One of the most significant physicochemical characteristics of aerosol particles is hygroscopicity, which is equally significant in many other fields of science and technology. disciplines. There are numerous experimental methodologies available to study aerosol hygroscopicity under subsaturated circumstances. These techniques vary in their concepts, setups, and cost. This work presents a detailed assessment of various methods, which are roughly categorized into four groups based on the preparation of the samples under inquiry. Using relevant examples from prior research to show how each technique can assist clarify aerosol hygroscopicity, we define each technique’s operation principle and typical configuration and go over its benefits and drawbacks
