One of the main causes of cancer is the misregulation of NF-κB receptors in the body. They are essential for the DNA transcription, cytokine synthesis and cell survival. This study includes the roles of different biomimetic particles involved in the activation of NF-kB pathway that leads to cancer. Nuclear factor-kB (NF-kB) transcription factors are involved in a variety of physiological processes, including innate and adaptive immunological responses, cell proliferation, cell death, and inflammation. It has been established that abnormal regulation of NF-kB and the signalling pathways that govern its activity play a role in cancer formation and development, as well as tolerance to chemo- and radiotherapy. Future treatment options in nanotech. for the treatment of cancer includes the conjugation of nanoparticles and antibodies in order to supress the activation of NF-kB receptor and the use of carbon-based nanomaterial like graphene.</span></p>2024-08-13T00:00:00+08:00Copyright (c) 2024 Malaysian NANO-An International Journalhttp://adum.um.edu.my/index.php/MNIJ/article/view/52648Employing carbon nanocomposites for the removal of hazardous contaminants from aqueous solution2024-06-07T11:14:13+08:00Kumar P. Senthil senthilkumarp@pondiuni.ac.in<p>Carbon nanocomposites have captured the curiosity of catalysis research and adsorption studies owing to their extremely small dimensions and shape-dependent chemical and physical properties. Metal nanomaterials and materials made of carbon, including graphene and carbon nanotube-based nanocomposites, displayed exceptional catalytic properties in organic chemical reactions. Carbon nanocomposites made from biomass are a low-cost, developing, and attractive technology for the production of surface-enhanced nanocomposites. For the elimination of all harmful pollutants, including dyes, heavy metals, emerging contaminants, and persistent organic contaminants, -based nanocomposites are utilised. As a result, the demand for carbon nanocomposites has been rising quickly, and the creation of new methods for preparing them deserves particular attention. This short review gives a comprehensive overview of several hazardous substances and their effects on the environment. Additionally, it examines the production, uses, and types of carbon nanocomposites as well as new developments in their capacity to remove organic contaminants from wastewater. In order to simultaneously remove contaminants from industrial effluent and advance the aims of environmentally friendly growth, future research is required. It's important to find an affordable technique to use carbon nanocomposites in wastewater treatment in large scale.</p>2024-08-13T00:00:00+08:00Copyright (c) 2024 Malaysian NANO-An International Journalhttp://adum.um.edu.my/index.php/MNIJ/article/view/52649Synthesis of PMMA-PEG@TiO2 nanocomposite by hydrothermal and sol-gel techniques for resveratrol delivery2024-06-07T11:40:13+08:00Jamespandi Annarajannaraj.chem@mkuniversity.org<p>TiO<sub>2</sub> nanoparticles were prepared using the sol-gel and hydrothermal procedures in order to compare their porosity, stability, and particle homogeneity as well as their encapsulation efficiency. Alcohol is converted into gel using the sol-gel method, which involves stirring it while it's hot, then drying, powdering, and calcining it. This simple process produces high-purity products, however due to agglomeration, it also produces unpredictable particle size and shape. On the other hand, hydrothermal approach requires enormous volumes at high pressure, which makes it slow and difficult to scale up. However, it is effective in producing uniform nanoparticles. Nanoparticles were synthesized using both methods to evaluate differences in drug loading and releasing capacities. TiO<sub>2</sub> was chosen for its excellent biocompatibility, mechanical strength, and chemical resistance, as well as its documented anticancer activity. To prevent premature drug release, the TiO<sub>2</sub> nanoparticles were coated with a copolymer of Poly(methyl methacrylate) and Polyethylene glycol (PMMA-PEG), which forms a mesh-like structure that enhances drug absorption and loading capacity. The drug Resveratrol was used in this study. The synthesized nanoparticles were characterized using X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV-Vis), and scanning electron microscopy (SEM) to analyze their structural and morphological properties. These characterization results facilitated the determination of the most effective synthesis method for creating TiO<sub>2</sub> nanoparticles with superior anticancer activity.</p>2024-08-13T00:00:00+08:00Copyright (c) 2024 Malaysian NANO-An International Journalhttp://adum.um.edu.my/index.php/MNIJ/article/view/53773Role of nanomaterials in food authentication techniques: A mini-review2024-07-28T01:39:01+08:00Motalib Hossain M.
