Background: Marine ecosystems, covering 70% of Earth’s surface, hold immense biodiversity and potential for biomaterials. Cuttlefish bone (CB) and marine resources have gained attention as eco-friendly biomaterials. Objectives: We aim to comprehensively study biomedical applications of CB-derived materials. By evaluating both in vivo and in vitro investigations, the review seeks to uncover the diverse potential of CB in the biomedical field. Methods: A comprehensive search of electronic databases yielded 51 articles from 2408 studies. These studies encompassed in vivo animal studies and in vitro investigations. Results: In vivo studies employed for bone repair, dorsal subcutaneous defects, thermal wound healing, muscle injections, and avian blood testing. In vitro studies focused on HAp synthesis, scaffold development, dental material enhancement, and antimicrobial properties. Risk of bias assessments revealed varying degrees of methodological quality in both animal and in vitro studies, underscoring the need for standardised reporting and rigorous study design in future research. Conclusions: This review fills a gap in the literature by providing a comprehensive overview of the applications of CB-derived materials in the biomedical field. Additionally, it offers valuable insights for researchers, clinicians, and policymakers interested in sustainable and effective biomaterials for diverse medical purposes, advancing the fields of regenerative medicine and dentistry.

Water pollution is a serious, persistent and emerging problem not only in Malaysia but all over the world. It has negative impacts on the sustainability of water resources, aquatic flora and fauna and community health. It significantly reduces total water availability because of the lack of suitable and cost-effective pollutant treatment facilities. Current facilities for water purification are time consuming, expensive and have low affinity and efficiency to newly emerging micro pollutants in water. Carbon nanotube (CNT) based nanocomposites and hybrids have attracted huge attention for their potential in the treatment of newly emerging micropollutants in water bodies. Addition of various molecules and binders such as magnetic nanoparticles, pollutant binding and degrading receptors and enzymes has added new dimensions in the fibrous shape, high aspect ratio, large surfaces, and accessible mesopores of CNTs. In this review, we have outlined the recent progress and future prospects of multifunctional CNT-hybrids for the treatment of both conventional priority and newly emerging micropollutants in water environment. The review also has highlighted the future strategies for overcoming the shortcomings of existing techniques and materials for water purification applications.

The unlimited applications of nanoparticles in human life are increasing day by day. Nanoparticles have drawn attention among researchers from academia to industry due to its large specific surface area, high chemical reactivity, physical affinity and interesting optical, electrical and magnetic properties. These properties of nanoparticles stimulate researchers to reduce particle sizes from few sub micrometers to nanometer levels. The successful application of nanoparticles depends on the simplicity of the methods for its cost effective synthesis. Since the very beginning of nanoscience, development of simple, low cost and high yielding methods has been a challenging task. Various approaches were proposed for the commercial production of nanomaterials from solid state. However, chemical method which is complicated and expensive showed limited success in the synthesis of controlled structure nanoparticles from rare-earth solid compounds. Among all the approaches, high energy ball milling with surfactant has been widely exploited for the synthesis of various nanomaterials, nanograins, nanocomposites from solid state. Self-assembled structures of surfactants provide a valuable tool for the controlled formation of nanostructure. In this process, the dispersion and enhanced grinding of particles are achieved in the reaction centers that reside in the microstructure of surfactants. In high-energy ball milling, plastic deformation, cold-welding and fracture are predominant factors which lead to a change in particle shape, size. These result in the formation of fine and dispersed particles. Stirred ball mill grinding is advantageous for nanoparticle production over other fine grinding techniques owing to its easy operation, simple construction, high size reduction rate and relatively low energy consumption. The aim of this systematic review is to represent the basic concept and applications of mechanical milling in the surfactant assisted synthesis of various nanomaterial, nanocomposite and nanocarbon materials.
