Abstract

This study aimed to develop eco-friendly biocomposites using acryloyl chloride as a graft monomer with tamarind kernel powder (TKP) as the polymer backbone and evaluate their antibacterial activity. The process involved the esterification of TKP with pre-synthesized acryloyl chloride as the grafting agent, resulting in a novel TKP derivative that enhances material properties. The biocomposites were subjected to comprehensive characterization, including morphological, structural, thermal, and antibacterial analyses. Through the modification with acrylic functionality, the biocomposite exhibited a crystallinity of approximately 51.77 %, a significant increase compared to the 33.56 % crystallinity observed in neat TKP. Moreover, the biocomposites showed enhanced antibacterial activity with an increase of 88 % against Escherichia coli and 74 % against Staphylococcus aureus holding potential for neat TKP. Given these improved characteristics the biocomposites hold potential applications in biomedical.

一种新型丙烯酰氧基罗望子核粉生物微粒和增强的抗菌活性

本研究旨在开发以丙烯酰氯为接枝单体、罗望子仁粉（TKP）为聚合物骨架的环保型生物复合材料，并评估其抗菌活性。这一过程包括将 TKP 与作为接枝剂的预合成丙烯酰氯进行酯化，从而得到一种可提高材料性能的新型 TKP 衍生物。对生物复合材料进行了全面的表征，包括形态、结构、热和抗菌分析。通过丙烯酸功能修饰，生物复合材料的结晶度约为 51.77%，与纯 TKP 33.56% 的结晶度相比有显著提高。此外，生物复合材料还显示出更强的抗菌活性，对大肠杆菌的抗菌活性提高了 88%，对金黄色葡萄球菌的抗菌活性提高了 74%，与纯 TKP 相比具有潜力。鉴于这些改进的特性，生物复合材料在生物医学领域具有潜在的应用前景。

期刊介绍： Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
