Presentation Abstract
Biofilms that form on material surfaces can cause material degradation, reduced machine performance, and hygiene issues in industrial and medical settings. In this study, silver-dispersed resin coatings were fabricated via vat photopolymerization, and their antibiofilm properties were investigated. Acrylic resin-based coatings containing alkoxysilane resin and dispersed silver particles were prepared at different silver contents, and the coated specimens were evaluated by crystal violet staining with absorbance measured at 595 nm. Anti-biofilm activity was quantified relative to a control specimen without silver. Raman spectroscopy and optical microscopy were also used to examine the dispersion state of silver in the coatings. The results showed that all silver-containing coatings exhibited anti-biofilm activity compared with the control, and the activity increased with silver content. The calculated anti-biofilm activity reached approximately 37%, 57%, and 75% for coatings containing 0.1 wt%, 0.5 wt%, and 1.0 wt% silver, respectively. Raman analysis suggested that silver was dispersed in the coatings, although some inhomogeneity remained. These findings indicate that vat photopolymerization is a promising route for fabricating functional resin coatings with anti-biofilm properties through silver dispersion.
Hideyuki Kanematsu, Ph.D., FASM, FIMF
Dr. Hideyuki Kanematsu is a Specially Appointed Professor at Osaka University and a Visiting Professor at Nagoya University. He previously served for approximately 35 years as a Distinguished Professor at the National Institute of Technology (KOSEN), Suzuka College, Mie, Japan, following seven years as an Assistant Professor at Nagoya University and Osaka University.
For more than 40 years, his research has focused on interfacial phenomena in materials from the viewpoint of physical chemistry. Since the turn of the century, he has concentrated on interactions between materials and bacterial or viral environments. In the 2020s, he expanded his work to the application of additive manufacturing technologies to antibacterial, antiviral, and anti-biofilm coatings.
Dr. Kanematsu received his B.Eng. (1981), M.Eng. (1983), and Ph.D. (1989) in Materials Science and Engineering from Nagoya University. He is a Fellow of ASM International (FASM) and a Fellow of the Institute of Materials Finishing (FIMF), United Kingdom. His core expertise lies in materials science, surface engineering, and electrochemistry.
In July 2024, he founded BEL Inc., where he serves as President. Through this venture, he is pursuing the challenge of translating his longstanding research achievements into real-world applications, particularly anti-biofilm coating technologies.
