"A team of researchers led by FUJITA Katsumasa (Professor, Graduate School of Engineering), KAWATA Satoshi (Professor, Graduate School of Engineering), and HASHIMOTO Hitoshi (Professor, Graduate School of Pharmaceutical Sciences) at Osaka University succeeded in nearly doubling the conventional resolution of Raman scattering microscopy, which is used in a wide variety of fields in science and industry ranging from drug discovery to device development.

Raman scattering is a very subtle effect, so it was thought difficult to increase the resolution of Raman scattering microscopy. However, this group 

succeeded in measuring at high spatial resolution by shedding dashed light on samples, achieving the highest resolution of microscopy using propagating light.

This group’s research results have made it possible to observe spatial distribution of drugs and device materials in further detail, which is expected to be helpful in enhancing the quality and functionality of products." (ResOU, Osaka University.)
