摘要

本研究的目的是设计和合成与紫杉醇偶联的金纳米颗粒(GNPs)，并研究影响合成纳米颗粒稳定性和给药能力的参数。在这里，合成的GNPs被聚乙二醇包裹。利用紫外分光光度计、傅里叶变换红外光谱、透射电镜、动态光散射和zeta电位仪等研究了纳米粒子与紫杉醇在不同条件下的共轭，考察了纳米粒子的物理结构特性以及影响紫杉醇负载的因素。结果发现，聚乙二醇化GNPs在孵育24 h时具有有限的负载能力，并且观察到紫杉醇负载与pH有关。这些颗粒在治疗乳腺癌(MCF7)中的应用也通过MTT试验进行了研究。结果表明，在最大浓度(690 μM)下，紫杉醇结合纳米颗粒对MCF7细胞的存活率降低至55%左右。

Evaluation of the parameters affecting the loading of anticancer drug Paclitaxel on coated gold nanoparticles for breast cancer treatment

The purpose of this study is the design and synthesis of gold nanoparticles (GNPs) conjugated with paclitaxel and to investigate the parameters affecting the stability of synthesised nanoparticles with drug delivery capability. Here, synthesised GNPs were coated with polyethylene glycol. Then these particles were conjugated with paclitaxel under different conditions and the physical and structural characteristics, as well as the factors affecting the loading of paclitaxel on nanoparticles, were evaluated by ultraviolet spectrophotometer, fourier transform infrared spectroscopy, transmission electron microscopy, dynamic light scattering and zeta potential apparatus. It was found that pegylated GNPs have a limited loading capacity at the time of 24 h of incubation and the Paclitaxel loading was observed to be pH dependent. The use of these particles in the treatment of breast cancer (MCF7) was also investigated using the MTT test. It was determined that the survival percentage of MCF7 cells in the presence of paclitaxel-bound nanoparticles decreases to about 55% at the maximum measured concentration (690 μM).

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 Societal issues such as health and the environment Special issues.
