Ten novel azo acid dyes were synthesized from benzimidazole derivatives using H-acid, Gamma acid, J-acid and Tobias . The synthesized intermediates and dyes were characterised and their properties and structures confirmed using UV–Visible, FT-IR and 1H-NMR spectroscopic techniques. The electronic absorption spectra of the synthesized dyes were within the wavelength range of 492‒660 nm in DMF at a uniform absorption intensity ranging from (0.18‒2.03) × 104 L.mol− 1 cm− 1 The FT-IR spectra of all the dyes showed peaks within the range of 3365‒3712 (cm− 1) corresponding to O–H stretching; 3425‒3362 (cm− 1) indicating N–H stretching; 1643‒1476 (cm− 1) confirming the presence of (–N = N-) and 1431.3‒1185 (cm− 1) which are attributed to (S = O) stretching. The 1H-NMR (δ) spectra of the dyes confirmed the presence of methyne (-CH-) groups between the range of 1.50‒1.89 ppm; methylene (-CH2-) groups between 1.27 and 1.47 ppm; methyl (-CH3-) groups between 1.16 and 1.20 ppm; aromatic protons between 6.78 and 8.63 ppm and carboxylic acid (-RCOOH) group between 10.36 and 12.78 ppm.

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.
