Raman microscopy maps of drug-delivery vehicles.

The article presents a study on microspheres using a Raman microscopy technique by the Agency for Science, Technology, and Research (ASTAR) and Nanyang Technological University researchers in Singapore. It notes that the study aims to obtain chemical information about microspheres which can be helpful in developing techniques. It mentions that double-walled microspheres provide more advantages for controlled drug release compared to single-walled version.
