“…The fourth presentation in this category featured Dr. Genin Gary Huang (Department of Medical and Applied Chemistry, Kaohsiung Medical University, Taiwan) and his hybrid composites modified with metal nanoparticles (Ag, Ag/Au, and magnetite/Ag) for SERS substrates. These substrates could be applied in catalytical reactions, immunoassays, and gas sensing . Dr. Ming‐shan Tsai (Department of Electrophysics, National Chiayi University, Taiwan) reported on the modulation of SERS signals of 4‐aminothiophenol absorbed on Ag nanoparticles using electrophoresis technique on SiO 2 nanospheres.…”

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.

“…It is believed that the signal enhancement of Raman intensity can be attributed mostly to the electromagnetic enhancement (EM) while the contribution from the charge transfer mechanism (CT) is also significant. EM is related to the morphologies of the substrates, and CT is related to the molecule–substrate charge transfer at the Fermi levels. − SERS has been utilized in diverse research fields due to these advantages, such as forensic science, − biosensing, − medical applications, ,− environmental analysis, and catalysis. , Although SERS has been studied extensively, it has several limitations related to the reproducibility of substrate morphologies, the stability of the substrates, and the restriction of substrates pertaining to substantial localized surface plasmon resonance (LSPR) behavior.…”

Galvanic replacement (GR) is a widely used method to obtain substrates with nanostructure morphologies. However, there are substantial challenges related to the uniformity of the deposited nanostructures, the preparation of large-area nanocomposites, and the alteration of the morphologies deposited on substrates. Graphene was introduced into the surface of the aluminum panels in this study prior to conducting the GR reaction to incorporate graphene advantages of extremely high electrical conductivity and electron mobility. The experimental results revealed that the morphological consistency and particle densities of gold nanoparticles deposited on panels with graphene were much higher than those deposited on panels without graphene. Moreover, gold nanoparticles were deposited on the surfaces with graphene prior to deposition on those without graphene. Ordered large-area gold/graphene/aluminum hybrid nanocomposites can be obtained with desired morphologies by altering the preparation conditions. Finally, the feasibility of using the as-prepared gold hybrid nanocomposites as surface-enhanced Raman scattering (SERS) substrates was examined. The results indicated that the Raman signal enhancement factors of the as prepared substrates were varied as the preparation condition changed due to the difference in the morphologies. Under the optimal condition, a high enhancement factor of approximately 3 × 108 with good reproducibility was found, which demonstrates the potential of utilizing the as-prepared gold hybrid nanocomposites in SERS and other sensing applications.
