Abstract
Zinc sulphide (ZnS) nanoparticles were synthesized by the coprecipitation method. The ZnS nanoparticle surface was polymerized with allyl glycidyl ether (AGE), and 3-aminophenol was then deposited as a ligand on nanosorbent. The modified nanosorbent was investigated with Fourier transform infrared spectroscopy and thermogravimetric analysis. The particle size of the modified nanosorbent was studied with scanning electron microscopy. Some characteristic factors of the adsorption process such as pH and time were investigated for famotidine using the modified nanosorbent. The equilibrium adsorption study of famotidine by 3-aminophenol-grafted AGE/ZnS was analysed by adsorption isotherms of the Langmuir, Freundlich, and Temkin models. The famotidine-releasing process was investigated in simulated biological fluids (intestinal fluid at pH of 7.4 and gastric fluid at pH of 1.2) and demonstrated 65% and 73% famotidine release during periods of 30 h (pH = 7.4) and 60 min (pH = 1.2), respectively. These results reveal the optimal performance of 3-aminophenol-grafted AGE/ZnS for sustained drug delivery.
采用共沉淀法合成了硫化锌纳米颗粒。将纳米ZnS表面与烯丙基缩水甘油酯醚(AGE)聚合,并将3-氨基苯酚作为配体沉积在纳米吸附剂上。采用傅里叶变换红外光谱和热重分析对改性纳米吸附剂进行了研究。用扫描电镜研究了改性纳米吸附剂的粒径。考察了pH、时间等对法莫替丁吸附过程的影响。采用Langmuir、Freundlich和Temkin吸附等温线模型分析了3-氨基酚接枝的AGE/ZnS对法莫替丁的平衡吸附。研究了法莫替丁在模拟生物液(pH为7.4的肠液和pH为1.2的胃液)中的释放过程,结果表明,在30 h (pH = 7.4)和60 min (pH = 1.2)的释放时间内,法莫替丁的释放量分别为65%和73%。这些结果表明,3-氨基酚接枝的AGE/ZnS具有持续给药的最佳性能。
期刊介绍:
Electrical and electronic engineers have a long and illustrious history of contributing new theories and technologies to the biomedical sciences. This includes the cable theory for understanding the transmission of electrical signals in nerve axons and muscle fibres; dielectric techniques that advanced the understanding of cell membrane structures and membrane ion channels; electron and atomic force microscopy for investigating cells at the molecular level.
Other engineering disciplines, along with contributions from the biological, chemical, materials and physical sciences, continue to provide groundbreaking contributions to this subject at the molecular and submolecular level. Our subject now extends from single molecule measurements using scanning probe techniques, through to interactions between cells and microstructures, micro- and nano-fluidics, and aspects of lab-on-chip technologies. The primary aim of IET Nanobiotechnology is to provide a vital resource for academic and industrial researchers operating in this exciting cross-disciplinary activity. We can only achieve this by publishing cutting edge research papers and expert review articles from the international engineering and scientific community. To attract such contributions we will exercise a commitment to our authors by ensuring that their manuscripts receive rapid constructive peer opinions and feedback across interdisciplinary boundaries.
IET Nanobiotechnology covers all aspects of research and emerging technologies including, but not limited to:
Fundamental theories and concepts applied to biomedical-related devices and methods at the micro- and nano-scale (including methods that employ electrokinetic, electrohydrodynamic, and optical trapping techniques)
Micromachining and microfabrication tools and techniques applied to the top-down approach to nanobiotechnology
Nanomachining and nanofabrication tools and techniques directed towards biomedical and biotechnological applications (e.g. applications of atomic force microscopy, scanning probe microscopy and related tools)
Colloid chemistry applied to nanobiotechnology (e.g. cosmetics, suntan lotions, bio-active nanoparticles)
Biosynthesis (also known as green synthesis) of nanoparticles; to be considered for publication, research papers in this area must be directed principally towards biomedical research and especially if they encompass in vivo models or proofs of concept. We welcome papers that are application-orientated or offer new concepts of substantial biomedical importance
Techniques for probing cell physiology, cell adhesion sites and cell-cell communication
Molecular self-assembly, including concepts of supramolecular chemistry, molecular recognition, and DNA nanotechnology
