The 5th International Taiwan Symposium on Raman Spectroscopy (TISRS 2017) and Taiwan Association of Raman Spectroscopy (TARS) Summer Camp were held from June 27th to 30th at National Chiayi University in Taiwan. Four plenary speakers and 14 invited speakers, from France, Hong Kong, India, Italy, Japan, New Zealand, Taiwan, and United States, presented their research findings in TISRS in front of an audience of more than 200 participants from 12 countries. Thirty-seven posters in biology and material sciences were exhibited at the symposium. Following TISRS, five experts delivered lectures to students in the summer camp. The mission of this congress was to promote continuous developments and applications of Raman spectroscopy, with a focus this year on surface-enhanced Raman scattering (SERS), tip-enhanced Raman spectroscopy (TERS), imaging methods, and their applications to molecular, biological, and nanomaterial sciences. This meeting also served as a platform for junior researchers to exhibit their recent studies. In this report, we highlight novel findings and perspectives in Raman spectroscopy that emerged in this symposium. The topics of lecture given in the summer camp are listed.
