Evaluation of dyeing efficiency of novel benzimidazole-derived azo dyes on nylon 6, 6 fabrics
Published in Social Sciences, Chemistry, and Mechanical Engineering
Ten novel azo acid dyes were synthesized from benzimidazole derivatives using H-acid, Gamma acid, J-acid and Tobias acid as the coupling components and both the synthesized intermediates and the dyes were characterised and their properties and structures confirmed using UV–Visible, FT-IR and 1H NMR spectroscopic techniques. The dyeing efficiency of the dyes was investigated on nylon 6, 6 fabrics, and the fastness to perspiration, light and washing were assessed. They showed very good percentage exhaustion (64–89)% on nylon 6, 6 with bright and dark intense hues of red, blue and purple. The novel azo acid dyes showed very good to excellent (4–5) fastness to perspiration, fair to very good fastness to light (3–6) and also fair to very good fastness to washing (2–4). The dyes showed moderate fastness results when compared with a commercial acid dye, Serilene Dark Red FL (4–5; 7 and 5 for fastness to perspiration, light and washing).
The novel dyes outperformed similar acid dyes produced in 2023 by two different researchers in terms of wash fastness and light fastness on nylon 6, 6 fabrics.

Advances in Material Chemistry for Life Science Research
Material chemistry has a long-standing history and has been extensively exploited in a wide range of life science research such as biological, chemical, and environmental engineering. The invention of novel materials for biological applications has led to the creation of biomaterials for tissue engineering, nanomaterials for drug delivery, and smart materials that interact dynamically with biological systems. These advances have significantly revolutionized the fields of healthcare including medical treatments, diagnostics, and biological studies. In recent years, the synergy between material chemistry and life sciences has been particularly evident in the development of materials that enable precision medicine, improve the accuracy of diagnosis, and facilitate regeneration of defected tissues. In particular, nanoparticles engineered for targeted drug delivery have significantly enhanced the efficacy of treatments while minimizing side effects, and responsive biomaterials have opened new avenues for developing adaptive therapeutic devices. The application of these advanced materials in life science not only enhances our understanding of biological processes but also paves the way for innovative solutions to pressing healthcare challenges. This topical collection aims to cover papers that explore the intersection of material chemistry and life sciences, focusing on the design, synthesis, and application of advanced materials in biological contexts. Translational advances in material chemistry for healthcare, biotechnology, and environmental sustainability will be highlighted in this topical collection, reflecting the multidisciplinary nature of this rapidly evolving field.

Material Chemistry in Biomedical Applications
Chemistry-driven processes are essential inspirations for researchers to design biomaterials applied as promising diagnostic tools, therapeutic solutions or tissue substitutes, etc. To increase the understanding of material chemistry in biomedical applications, this topical collection focuses on documenting the chemistry covering nanoscale to macroscale biomaterials, including surface science and interactions with the body at the molecular level. We seek articles that highlight the principles of material chemistry or approaches to investigate and improve the material properties in biomedical research. The material properties here mainly include biocompatibility, physical, chemical, mechanical, and other particular properties required for medical and dental materials. Reviews, original research, and commentaries are all welcomed.
Keywords: Material chemistry, surface science, nanotechnology, biocompatibility, physical and chemical property, mechanical property, biomedical application.
