Three Research Presentations on the Application of Silver-Loaded Nanosized Zeolites to Coatings at the 154th Conference of the Surface Finishing Society of Japan
Silver-loaded nanosized zeolites are expected to suppress biofilm formation and biological fouling on material surfaces through the antimicrobial activity of silver, thereby contributing to the reduction of corrosion of underlying steel materials. In these presentations, we reported on the dispersion and its control of nanosized zeolites in silicone and acrylic resins, the inhibition of biofilm formation on coated surfaces, and the relationship between biological fouling and corrosion behavior in marine environments.
In particular, marine immersion tests were conducted to quantitatively evaluate the corrosion-inhibiting effects of the coatings using image analysis and persistent homology. The relationship between corrosion behavior and biofilm formation was also investigated.
The three presentations were as follows:

Patent Application Filed for Material Surface Evaluation Technology Using Persistent Homology
BEL Inc. has filed a patent application with the Japan Patent Office (JPO) for a technology that evaluates material surface conditions using persistent homology.
The technology has been developed to enable more quantitative evaluation of surface conditions, including biofilms formed on material surfaces and associated corrosion phenomena, complementing conventional evaluation methods.
Persistent homology is a topological data analysis technique for capturing intrinsic shapes and structural features within complex data. BEL has been exploring the application of this approach to material surface evaluation, and part of the成果 from this research has led to the present patent application.
BEL also plans to pursue international protection of the technology by filing an international patent application under the Patent Cooperation Treaty (PCT) in the near future.

Presentation on Topological Fingerprinting of Biofilm Raman Spectra at the ACS 2026 Fall Meeting
On August 25, 2026, we presented our research on the analysis of biofilm Raman spectra using persistent homology at the ACS 2026 Fall Meeting of the American Chemical Society (ACS).
In this study, we proposed a new approach for analyzing Raman spectra of biofilms formed on material surfaces. Rather than relying solely on the identification of individual characteristic peaks, the proposed method uses persistent homology to capture patterns and structural features across the entire Raman spectrum, enabling a more holistic characterization of complex spectral data.
Persistent homology is a topological data analysis technique that captures intrinsic shapes and structural features within complex datasets. We hope that this study will contribute to expanding the application of persistent homology not only to spectroscopic evaluation of biofilms but also to the analysis of complex spectral data in a broader range of materials research.

Critical Review on International Standards for Evaluating Antibacterial, Antiviral, and Antibiofilm Properties Published in Transactions of the IMF
On August 11, 2026, our review article on international standards for evaluating the antibacterial, antiviral, and antibiofilm properties of surface-finished materials was published online in Transactions of the IMF, the flagship journal of the UK-based Institute of Materials Finishing (IMF).
The review critically examines international standards for evaluating the antibacterial, antiviral, and antibiofilm properties of surface-finished materials, summarizing their respective evaluation principles, characteristics, and challenges.
To properly evaluate biological functionalities imparted to material surfaces, it is essential to understand what each test method and international standard actually measures. We hope that this review will provide a useful reference for selecting appropriate evaluation methods, from the research and development of functional surface materials through their practical application and standardization.

Publication on Anti-Biofilm Properties of Additively Manufactured Surfaces in AM Future
In August 2026, we published an article entitled “Anti-Biofilm Properties of Additively Manufactured Surfaces Dispersed with Antimicrobial Agents” in AM Future, the flagship publication of the Japanese Institute of Additive Manufacturing.
In this study, silver-ion-loaded nanosized zeolite produced by ZeoNext Corporation was dispersed in silicone and acrylic resins to prepare functional coating materials. The relationship between the dispersion of the antimicrobial material within these resins and the resulting anti-biofilm performance was investigated.
To impart antimicrobial and anti-biofilm functionality to additively manufactured (AM) surfaces, not only the intrinsic properties of the antimicrobial agent but also its dispersion within the material and its compatibility with the resin matrix are important factors. From this perspective, the article discusses the potential of these composite systems as functional coating materials for additively manufactured surfaces.

Excerpt from the Lecture Manuscript
Excerpt from the Lecture Manuscript
“Whether you think you can or think you can’t – you are right.”
— Henry Ford
Introduction
The words of the automobile pioneer Henry Ford quoted above suggest that whether one believes something is possible or impossible, the outcome often follows that belief. Put more gently, if we believe something can be achieved, a path may open; if we assume it cannot be done, progress may stop before it even begins.
As is well known, Ford was not only an engineer but also an entrepreneur. At that time, the mass production of automobiles was widely considered nearly impossible. Nevertheless, he succeeded in making it a reality.
In this sense, Ford’s statement represents an entrepreneurial perspective: the future branches according to whether we first believe in its possibility.
Those who believe something can be done tend to experiment, innovate, and persevere, while those who assume it cannot be done often hesitate to act or abandon their efforts after small failures. As a result, their paths diverge in reality.
Ultimately, Ford’s message may be interpreted as an entrepreneurial insight: possibility does not begin as an objective fact, but rather as a conviction formed in the mind.

Title:
Comparison of Biofilm Formation Under Shear Stress Using Different Reactor Systems
Authors:
Hideyuki Kanematsu, Risa Kawai, Michiko Yoshitake, Takayoshi Nakano
Abstract:
In this study, two types of cylindrical laboratory-scale biofilm reactors that provide different shear-flow environments were employed. In Reactor A, test coupons are mounted on the inner wall of a vertical cylinder, and a bacterial suspension is continuously supplied from the bottom to the top in a direction parallel to the coupon surface, thereby generating a laminar shear field along the surface. In Reactor B, a cylinder of the same geometry is placed horizontally and rotated, which applies a circumferential shear field to the test coupons attached to its interior.
Both reactors are operated under controlled flow rate and nutrient conditions, and biofilm formation is evaluated via visual inspection, microscopic observation, and stained-image analysis in accordance with ISO 4768 (2023). Using Particleworks (Prometech Software Co., Ltd.), we performed numerical analysis of the shear-stress distributions acting on biofilms formed under parallel-flow and circumferential-flow conditions. We then calculated the shear-stress distribution for a tank-type reactor planned for future fabrication. Based on these results, we examined the operating conditions under which a reactor with circumferential flow can reproduce shear-stress levels comparable to those in an upward-flow vertical reactor.
