Preface of the International Symposium on Nanotechnology for Medicine, Environment and Energy ^†

1. Introduction

The International Symposium on Nanotechnology in Medicine, Environment and Energy (SINAMEV 2025) was organized by the Center for Research in Micro and Nanotechnology, the Institute of Medical-Biological Research, the Institute for Health Sciences, the Faculty of Chemical Sciences, and the Faculty of Bioanalysis of the Universidad Veracruzana in Boca del Río, Veracruz, Mexico.

Conceived as a multidisciplinary meeting point, SINAMEV 2025 brought together researchers, students, and professionals working across the fields of nanotechnology, health, environmental protection, and energy. The symposium placed strong emphasis on using nanotechnology responsibly, promoting scientific dialog, and strengthening national and international collaborations aimed at addressing contemporary societal and technological challenges through advanced nanomaterials and nanosystems.

The scientific program encompassed a wide range of themes, including biosensors, microarrays, lab-on-a-chip devices, environmental nanotechnology and remediation, nanocatalysis, photovoltaic and energy-harvesting materials, supercapacitors, smart coatings, thermal insulators, nanomembranes, nanofilters, superhydrophilic surfaces, and alternative electrode materials. In the biomedical field, the symposium highlighted imaging and in situ diagnostic platforms, drug design and targeted delivery, biomaterials and tissue engineering, and nano-enabled strategies for bone and neuronal regeneration and antimicrobial protection.

All contributions included in this volume of Materials Proceedings underwent a rigorous peer-review process in accordance with the journal’s editorial standards and the scientific guidelines established by the SINAMEV 2025 Scientific Committee. The accepted papers showcase recent advances in the synthesis, processing, characterization, and application of nanomaterials, with particular attention to sustainability, environmental responsibility, and translational potential in medical and energy-related technologies.

We extend our sincere appreciation to the members of the Scientific and Organizing Committees for their dedication throughout the review and preparation stages of the symposium. We also thank the authors and participants whose engagement and contributions

enriched the discussions and helped consolidate SINAMEV 2025 as a dynamic and collaborative scientific forum.

We hope that this volume of Materials Proceedings will serve not only as a record of the research presented at SINAMEV 2025 but also as a valuable reference for the broader community working on nanotechnology-based solutions for medicine, environmental protection, and energy, fostering new ideas, partnerships, and innovations.
