Gold Particle(金粒)研究综述
Gold Particle 金粒 - Although most gold particles were intracellular, 28% of SEP-D2R gold was irregularly distributed along the plasma membrane. [1] Objective(s): It has been shown that Nanogold particles have anti-inflammatory effects in different Rheumatologic, neurologic and gastrointestinal disease. [2] Prior to human epithelial cell stimulation (HCE), the gold particles were removed and the serum was diluted in DMEM (10% or 30%). [3] Suvarna Bhasma (SB) is a gold particle-based medicine that is used in Ayurved to treat tuberculosis, arthritis and nervous diseases. [4] Furthermore, endosomes of astrocytes contained nanogold particles together with digested materials, suggesting a compensatory phagocytic activity upon microglial depletion. [5] A combined study was undertaken of gold particles from hypogene mineralization and locally derived eluvial material, as well as gold from alluvial deposits in local drainages, to assess possible sources of the alluvial gold. [6] The morphological and chemical characters of the gold particles have evolved from the mineralized zone to the surface. [7] Electron microscopic immunolabeling showed M1R-immunogold particles on plasma membranes and in association with cytoplasmic membranes in varying sized dendrites and dendritic spines. [8] An atmospheric-pressure plasma-assisted chemical deposition process that can deposit an even distribution of nanogold particles in a one-step process has been developed. [9] Two nanogold particles are labeled at two target sites, and the interparticle distance is measured as a structural parameter via cryo-electron microscopy (cryo-EM). [10] The device consists of a nitrocellulose membrane with two immobilized antibody zones and a running buffer with gold particles. [11] Two different shapes of gold particles, including spherical AuNPs (50 & 100 nm) and gold nanorods (AuNRs) with three different sizes (20, 50 and 100 nm length) were synthesized using the chemical reduction method. [12] The gold particles are irregular disk shaped, but agglomerated to each other and not in uniform size. [13] Atomic absorption spectroscopy confirmed the cellular uptake of the gold particles. [14] The biolistic delivery of gold particles coated with plasmids expressing CRISPR/Cas9 components designed to target TaQsd1 were bombarded into the embryos of imbibed seeds with their shoot apical meristem (SAM) exposed. [15]尽管大多数金颗粒在细胞内，但 28% 的 SEP-D2R 金沿质膜不规则分布。 [1] 目的：已经表明纳米金颗粒在不同的风湿病、神经病学和胃肠道疾病中具有抗炎作用。 [2] 在人上皮细胞刺激 (HCE) 之前，去除金颗粒并将血清稀释在 DMEM (10% 或 30%) 中。 [3] Suvarna Bhasma (SB) 是一种基于金颗粒的药物，用于 Ayurved 治疗肺结核、关节炎和神经疾病。 [4] 此外，星形胶质细胞的内体含有纳米金颗粒和消化的物质，表明小胶质细胞耗竭后具有补偿性吞噬活性。 [5] 对来自浅成矿化和当地冲积物质的金颗粒以及来自当地排水沟冲积沉积物的金进行了综合研究，以评估冲积金的可能来源。 [6] 金颗粒的形态和化学特征从矿化带演化到地表。 [7] 电子显微镜免疫标记显示 M1R 免疫金颗粒在质膜上，并与不同大小的树突和树突棘中的细胞质膜结合。 [8] 已经开发出一种大气压等离子体辅助化学沉积工艺，该工艺可以在一步工艺中沉积均匀分布的纳米金颗粒。 [9] 两个纳米金颗粒在两个目标位点被标记，颗粒间距离通过低温电子显微镜 (cryo-EM) 测量为结构参数。 [10] 该装置由具有两个固定抗体区的硝酸纤维素膜和带有金颗粒的运行缓冲液组成。 [11] 使用化学还原法合成了两种不同形状的金颗粒，包括球形 AuNP（50 和 100 nm）和具有三种不同尺寸（20、50 和 100 nm 长度）的金纳米棒 (AuNR)。 [12] 金颗粒呈不规则的圆盘状，但相互团聚，大小不一。 [13] 原子吸收光谱证实了金颗粒的细胞吸收。 [14] 将涂有表达 CRISPR/Cas9 成分的质粒的金颗粒以 TaQsd1 为目标进行基因枪击，这些金颗粒被轰击到吸收种子的胚胎中，并暴露出它们的茎尖分生组织 (SAM)。 [15]
Colloidal Gold Particle 胶体金粒子
Colloidal gold particles could be chelated and aggregated by EDTA-K2, but not by sodium citrate, lithium heparin and coagulants. [1] Here, we used the SE-ADM system to observe LC3- and Atg12-containing autophagosomes in cells labelled in the culture medium with antibodies conjugated to colloidal gold particles. [2] The polymerization of colloidal gold particles enables us to detect the new coronavirus antigen’s appearance. [3] Using CHO cell-expressed full length SARS-CoV2 S1 protein as coating antigen on colloidal gold particles, a SARS-CoV-2 S1 IgG-IgM antibody lateral flow test kit (POCT) was developed. [4] This model explains how bonanza veins may form from fluids containing ppb concentrations of gold and does not require prior encapsulation of colloidal gold particles in silica gel, as proposed by previous studies. [5] The results of four colloidal gold particle-labeled LFIAs and polymerase chain reaction (PCR) simultaneously detected in actual samples were to be highly consistent, indicating that strips have high accuracy. [6]胶体金颗粒可以被 EDTA-K2 螯合和聚集，但不能被柠檬酸钠、肝素锂和促凝剂螯合。 [1] 在这里，我们使用 SE-ADM 系统观察细胞中含有 LC3 和 Atg12 的自噬体，这些细胞在培养基中标记有与胶体金颗粒结合的抗体。 [2] nan [3] nan [4] nan [5] nan [6]
Spherical Gold Particle 球形金颗粒
Experimentally, we demonstrate the separation of spherical gold particles of nominal 80 and 100 nm diameters with an applied voltage of 3. [1] Due to the much lower surface energy of the silica-air heterostructure compared to metallic materials, deposited gold layers dewetted the surface spontaneously, forming nano-sized spherical gold particles without the requirement of an extra annealing process. [2] The generated gold film contains two different layers involving uniform spherical gold particles attached to the PDMS surface with the complex hierarchical structures on top. [3] As a proof-of-concept, the fluorescence emission from antennas assembled with both conventional and ultrasmooth spherical gold particles is measured. [4]通过实验，我们展示了在施加电压为 3 的情况下分离标称直径为 80 和 100 nm 的球形金颗粒。 [1] 由于与金属材料相比，二氧化硅-空气异质结构的表面能低得多，沉积的金层自发地使表面去湿，形成纳米级球形金颗粒，无需额外的退火工艺。 [2] nan [3] nan [4]
Nm Gold Particle Nm 金颗粒
Catalysts with similar gold dispersion (2-5 nm gold particles) were prepared by a deposition-precipitation method. [1] Using a short transverse DNA double-strand, we introduce five dye molecules in the gap between two 40 nm gold particles and actively decrease its length down to sub-2 nm values by screening electrostatic repulsion between the particles at high ionic strengths. [2] After an 1 h of incubation followed by a 24 h chase time, 14 nm gold particles carrying an adenoviral NLS are localized in endosomes, in the cytoplasm, and in the nucleus of fibroblast cells. [3] The concentration of highly active 2–4 nm gold particles in Au catalysts is influenced by the support’s texture; this concentration increases in the following order: Au/TiO2 < Au/ZrO2 < Au/C < Au/SiO2 << Au/Al2O3. [4]通过沉积-沉淀法制备具有类似金分散体（2-5 nm 金颗粒）的催化剂。 [1] 使用短的横向 DNA 双链，我们在两个 40 nm 金颗粒之间的间隙中引入五个染料分子，并通过在高离子强度下筛选颗粒之间的静电排斥，主动将其长度降至 2 nm 以下值。 [2] nan [3] nan [4]
Native Gold Particle 原生金粒子
The growth history of individual native gold particles is documented by nano- to micro-textural investigations of sample grains ranging from isolated semi-spherical nanoparticles through agglomerates to irregularly shaped platy micro-nuggets of gold. [1] —The ratios of vein and ore minerals bearing native gold, the shape and size native gold particles, their surface features, variations in chemical composition, and the presence and distribution of impurities and inclusions in them, allow sufficiently substantiated assumptions about ore-forming settings and composition, phase state, and certain other parameters of ore-forming fluids that precipitated native gold. [2] Electron microscopy (using electron probe scanning on an energy dispersive spectrometer) of native gold particles revealed foreign inclusions - adsorbed mineral particles of calcite (CaCO3) and, presumably, a surface film consisting of aluminum oxide (Al2O3), which create a significant obstacle to the contact of leaching agents with the surface of the target gold grains. [3]单个天然金颗粒的生长历史通过对样品颗粒的纳米到微观纹理研究进行记录，从孤立的半球形纳米颗粒到附聚物，再到不规则形状的金片状微金块。 [1] — 含天然金的脉状矿物和矿石矿物的比例、天然金颗粒的形状和大小、它们的表面特征、化学成分的变化以及杂质和夹杂物的存在和分布，允许对成矿环境进行充分证实的假设以及沉淀天然金的成矿流体的成分、相态和某些其他参数。 [2] 原生金颗粒的电子显微镜（在能量色散光谱仪上使用电子探针扫描）揭示了外来夹杂物 - 吸附的方解石矿物颗粒 (CaCO3)，并且可能是由氧化铝 (Al2O3) 组成的表面膜，这对浸出剂与目标金粒表面的接触。 [3]
Nano Gold Particle 纳米金粒子
The gold in pyrite of the Ashawayi deposit dominantly exists in the form of nano gold inclusions or is present as micro-nano gold particles in the cracks or edges of pyrite, some of which can exist as lattice gold. [1] The results with XRD, FESEM-EDX and UV analysis studies from present investigations clearly confirm about the presence of nano gold particles and its by products. [2] This paper analyses the possibility of obtaining surface-infused nano gold particles with the polyether ether ketone (PEEK) using picosecond laser treatment. [3]Ashawayi矿床黄铁矿中的金主要以纳米金包裹体的形式存在，或者以微纳米金颗粒的形式存在于黄铁矿的裂缝或边缘，其中一些可以以晶格金的形式存在。 [1] 目前研究的 XRD、FESEM-EDX 和 UV 分析研究结果清楚地证实了纳米金颗粒及其副产物的存在。 [2] 本文分析了使用皮秒激光处理获得具有聚醚醚酮 (PEEK) 的表面注入纳米金颗粒的可能性。 [3]

The gold leaf was modified by electrodeposition of the gold network and large nano-size gold particles which significantly enhanced the sensitivity of all voltametric sensing, giving lower limits of detection. [1] The tiny size gold particles drift in free space of catheters having flexible walls with couple stress fluid. [2]金箔通过电沉积金网络和纳米级大金颗粒进行改性，显着提高了所有伏安传感的灵敏度，降低了检测限。 [1] nan [2]

Placer gold particles have traditionally been considered as either detrital products of weathering or authigenic minerals growing within placers. [1] Placer gold particles were obtained from a stream located in the Yelizovsky District and were compared to particles from regions at similar latitudes. [2]砂矿金颗粒传统上被认为是风化的碎屑产物或砂矿内生长的自生矿物。 [1] 砂金颗粒是从位于叶利佐夫斯基区的一条溪流中获得的，并与来自相似纬度地区的颗粒进行了比较。 [2]
gold particle size 金颗粒大小
Its main advantages over other immunolabeling methods for thin-section TEM are (1) fairly accurate and quantifiable localization of proteins in cells; (2) double-labeling of sections using two gold particle sizes; and (3) the ability to perform multiple labeling for different proteins by using adjacent sections. [1] The aims of this paper is to use gold element of electronic boards by adjusting its surface functionality and particle size to make this metal to be used in various applications to gain this purpose by using acidic solutions and up to bottom chemical synthesis method among physical, chemical, and biological methods and by transferring gold particle size from micrometer to nanometer, surface-area-to-volume ratio will be increase such that new structural properties emerge, change, or improve. [2] It is believed that cutaneous pigmentation appears immediately after Q-switched laser therapy due to reduction of the gold particle size [4]. [3] A relationship between the gold particle size, depending on the method of gold deposition, and the effectiveness of glucose oxidation to gluconic acid, expressed by glucose conversion and the selectivity to gluconic acid, was observed. [4] Choosing a proper preparation method is crucial to obtain optimal gold particle size. [5] The key parameters in gold nanoparticle-based plasmonic photocatalysts are the gold particle size and shape, and the state of junction between the components. [6]与其他用于薄切片 TEM 的免疫标记方法相比，它的主要优点是 (1) 相当准确和可量化的蛋白质在细胞中的定位； (2) 使用两种金颗粒大小对切片进行双重标记； (3) 使用相邻切片对不同蛋白质进行多重标记的能力。 [1] 本文的目的是利用电子板的金元素，通过调整其表面功能和粒度，使这种金属用于各种应用 为了达到这个目的，通过在物理、化学和生物方法中使用酸性溶液和自上而下的化学合成方法，并将金的粒度从微米转移到纳米，将增加表面积与体积比，从而产生新的结构性质出现、改变或改进。 [2] nan [3] nan [4] nan [5] nan [6]
