    • 摘要: 表面增强拉曼光谱技术对分子具有特异性识别以及快速无损检测的能力,使其在药物检测方面具有重大的潜力.通过贵金属和氮化钛之间协同作用,使复合基底具有较高的SERS性能,提供了一种基于SERS技术的药物检测方法.采用电化学沉积及自组装法,制备出贵金属/氮化钛复合薄膜.研究表明,在复合薄膜中存在面心立方晶型T iN、金属单质A u和A g三种物相;电子显微镜显示平均粒径分别为90和50 nm的金属Au和Ag颗粒均匀分布在TiN薄膜表面;基底的紫外-可见吸收图谱中出现了贵金属金与银纳米颗粒及TiN薄膜三者的特征等离子体共振吸收峰.以该复合薄膜为SERS基底,对烟酸溶液进行拉曼检测.结果显示,贵金属/氮化钛复合薄膜对烟酸具有显著的SERS效应,最低检测浓度为10-5 mol·L-1,对1033 cm-1处烟酸拉曼信号强度及浓度取对数,发现两者间呈一定线性关系,其R2为0.969,得益于T iN,Au和Ag之间可发生表面等离子体共振引起电磁场增强,以及电荷转移效应.研究还发现,烟酸通过COO-基团垂直吸附在贵金属/氮化钛基底表面;在酸性环境下,烟酸N原子质子化主要以阳离子N+H(Ⅰ)形式存在;在碱性环境时,主要以阴离子COO-(Ⅲ)形式存在.绞股蓝总甙溶液中模拟烟酸非法添加,该复合基底对其最低的拉曼检测浓度是10-5 mol·L-1,为现场快速检测非法添加药物提供了新途径.

    • 摘要: TFT-LCD(Thin film transistor-liquid crystal display)行业中,在对屏进行切割 、搬运过程中,容易造成屏边缘破损.当破损位置刚好位于屏点银胶位置时,银胶会通过破损进入,与黑矩阵(Black matrix,BM)接触,使黑矩阵带电形成干扰电场,从而使液晶偏转异常而产生发绿不良.切割工艺中,增加辅胶涂覆可以使切割后的空白条更稳定,从而减少搬运过程中摩擦 、碰撞导致的屏边缘破损,从而降低不良发生率,导入后不良发生率由5.6% 下降到1.5%.屏单侧点银胶是一种具有可行性的不良改善临时措施,但不具有量产导入性.通过对比相似产品银胶点位设计及产线工艺条件调查,得出当银胶点距离屏边缘 ≥4 mm时,可有效防止发绿不良的发生.在点银胶侧BM区域进行挖槽,使银胶与BM隔离开,可彻底避免静电由银胶导入黑矩阵.黑矩阵挖槽设计导入后,发绿不良降低为0%,不良彻底解决.

    • 摘要: 在中药治疗过程中,以方剂为载体,注重整体,采用辨证论治的方法. 为揭示方剂的药队规律,根据药队协同效应设计法,将活血化瘀汤方剂拆分为"调和"、"化瘀生新"、"活血止痛"、"补气"四个药队方剂. 由于银纳米粒子可与煎剂产生强交互作用,并极大地增强拉曼信号,获取活血化瘀汤、调和药队煎剂、化瘀生新药队煎剂、活血止痛药队煎剂和补气药队煎剂五种方剂煎剂的表面增强拉曼散射(SERS)光谱,并对所有SER S谱峰进行归属. 主要针对各煎剂中的18个拉曼信号(523,538,622,647,732,959,977,1 003,1 048,1 077,1 145,1 245,1 326,1 402,1 456,1 470,1 518和1 605 cm-1)进行讨论. 活血化瘀汤SERS光谱中保留了药队煎剂的某些拉曼峰,如: 538,622,647,732,959,1 003,1 048,1 326,1 402,1 456,1 470,1 518和1 605 cm-1. 药队煎剂SERS光谱的某些拉曼峰并未在活血化瘀汤中出现,如: 1 077,1 145和1 245 cm-1. 在活血化瘀汤SERS光谱中,出现了新的拉曼峰,如: 523和977 cm-1. 新的拉曼峰出现说明新物质的产生. 实验结果表明,活血化瘀汤所包含的药物成分并非是各药队煎剂所含药物成分的简单相加,SE RS光谱可为方剂药队规律研究提供一优异、有效和准确的检测方法.%In integrated treatment of traditional Chinese m edicine,prescriptions are used as carriers.Attention has been given to the int egration,and the methodology of treatment is based on syndrome differentiation.To reveal the rule of drug group in prescription,according to the own drug efficacy of traditional Chinese medicine,Huo-Xue-Hua-Yu decoction (HXHYD) w as divided into four drug-group decoctions as follow:Tiao-He drug group decoc tion (THDGD),Hua-Yu-Sheng-Xin drug group decoction (HYSXDGD),Huo-Xue-Zhi-Tong drug group decoction (HXZTDGD) and Bu-Qi drug group decoction (BQDGD).T here are strong interactions between Ag nanoparticles and decoction,thus leadin g to a tremendous enhancement in the intensity of the decoction Raman scattering,the Surface-enhanced Raman Scattering (SERS) spectroscopy of HXHYD,THDGD,HY SXDGD,HXZTDGD and BQDGD were obtained and analyzed,and the characteristic Rama n bands of five decoctions were tentatively assigned.Mainly eighteen Raman sign als (523,538,622,647,732,959,977,1 003,1 048,1 077,1 145,1 245,1 326,1 402,1 456,1 470,1 518 and 1 605 cm-1) i n five decoctions were discussed.Some Raman bands in SERS spectra of drug group decoctions were retained in the HXHYD,such as 538,622,647,732,959,1 003,1 048,1 326,1 402,1 456,1 470,1 518 and 1 605 cm-1.Ho weve r so me Raman bands never appeared in the HXHYD,such as 1 077,1 145 and 1 245 cm-1.New Raman bands were generated in the SERS spectra of HXHYD,such as523 and 977 cm-1,which meant new created chemical compositions.The re sults showed that medical ingredients in the HXHYD were not the simple addition of THDGD,HYSXDGD,HXZTDGD and BQDGD,and SERS technique has great potential for providing a novel method for effectively and accurately studying drug group rule of prescription.

    • 摘要: 为揭示单味煎剂与方剂间的关系,分别测试分析了生地当归药队、单味药生地和单味药当归煎剂的表面增强拉曼散射(surface-enhanced Raman scattering,SERS)光谱,并对其进行谱峰归属。本文主要针对存在于三种煎剂中的17个拉曼信号(538,622,732,761,835,876,959,1145,1245,1276,1326,1402,1456,1470,1518,1546和1605 cm-1)进行讨论。生地当归药队煎剂SERS光谱在538,732,761,835,876,959,1145,1245,1276,1326,1402,1456,1470,1518和1605 cm-1处,出现15个明显的拉曼信号;生地煎剂 SERS 光谱在538,761,835,876,959,1145,1245,1276,1326,1402,1470,1518和1546 cm-1处,出现13个明显的拉曼信号;当归煎剂 SERS光谱在538,622,732,761,835,876,959,1245,1326和1402 cm-1处,出现10个明显的拉曼信号。生地当归药队煎剂 SERS光谱保留了和未观察到生地和当归单味煎剂的某些拉曼峰,且产生了生地和当归单味煎剂中所没有的拉曼信号(1456和1605cm-1),即产生新药物成分。生地当归药队煎剂所包含的药物成分并非是生地和当归单味药物煎剂所含药物成分的简单相加。结果表明,SERS光谱可能为方剂研究提供一种高灵敏度、快速准确和操作简单的检测方法。%To reveal the relationship between the single decoction and prescription,the surface-enhanced Raman scattering (SERS)spectroscopy of Sheng-Di-Dang-Gui decoction (SDDGD),Sheng-Di decoction (SDD)and Dang-Gui decoction (DGD) were tested and analyzed.Mainly seventeen Raman signals (538,622,732,761,835,876,959,1 145,1 245,1 276,1 326, 1 402,1 456,1 470,1 518,1 546 and 1 605 cm-1 )in three decoctions were discussed.The characteristic Raman bands of three decoctions were tentatively assigned.Fifteen obvious Raman bands (538,732,761,835,876,959,1 145,1 245,1 276, 1 326,1 402,1 456,1 470,1 518 and 1 605 cm-1 )were observed in the SERS spectroscopy of SDDGD,thirteen obvious Raman bands (538,761,835,876,959,1 145,1 245,1 276,1 326,1 402,1 470,1 518 and 1 546 cm-1 )were observed in the SERS spectroscopy of SDD,ten obvious Raman bands (538,622,732,761,835,876,959,1 245,1 326 and 1 402 cm-1 )were ob-served in the SERS spectroscopy of DGD.Some Raman bands in SERS spectra of SDD and DGD were retained in the SDDGD, however some Raman bands in two kinds of decoctions never appeared in the SDDGD.And new Raman bands (1 456 and 1 605 cm-1 )were generated in the SDDGD,resulted in the fact that new chemical compositions were created.Medical ingredients in the SDDGD were not the simple addition of SDD and DGD.The results showed that the SERS spectroscopy might provide a new kind of novel,effective and simple detecting method for the prescription research.

    • 摘要: 发光二极管(LED)灯丝已成为研究热点,通过扫描电子显微镜(SEM)对LED倒装芯片焊接进行观察,发现锡膏焊接形成了第三相,而银胶固晶仅仅起粘结作用.采用推拉力和正向电压(@20 mA)测试发现,锡膏固晶的芯片推拉力是银胶的2倍,正向电压波动范围远小于银胶固晶.对锡膏固晶的热分布进行模拟和测试,发现灯丝中间温度高,两端温度低,理论与测试数据基本吻合.结果表明,锡膏焊接固晶方法更适合制备倒装LED.

    • 摘要: 胃癌患者能够得到早期诊断对其治疗具有十分重要的意义,疾病状态下的血红蛋白拉曼光谱检测在血液代用品的高铁血红蛋白含量检测中以及血氧饱和定量测定中占很大优势。本实验采用微波加热法制备银胶体粒子,依次对20例胃癌患者和11例健康人的血红蛋白进行表面增强拉曼光谱分析。采用SERS谱峰归属分析结果显示胃癌患者血红蛋白中的酪氨酸、苯丙氨酸和吡咯环的含量均低于正常人。本文还讨论了血红素的分子结构,在血红蛋白和氧气结合的前后,Fe2+分别处于高低自旋态,离子半径也随着与氧结合缩小了0.075 nm从而滑落入卟啉环平面中央的孔隙之中。这种空间的拉伸变化会牵动与铁相连的 F8 H is ,使得珠蛋白中两股螺旋之间空隙缩小,导致将 HC2酪氨酸排挤出空隙。利用这一机理,对血红蛋白1560 cm -1的吸收峰进行研究,证实了胃癌患者酪氨酸含量确实低于正常人。为了能得到更加明显的诊断区分,利用降维的思想,采用主成分分析(PCA )的方法对所有的拉曼光谱进行多元统计分析,得出三维的诊断散点图。为了更加精确的得出诊断准确率,用判别分析得出诊断的灵敏度和特异性分别为90.0%和90.9%,总判别正确率为90.3%。此项研究表明:对氧合血红蛋白的表面增强拉曼光谱诊断分析有希望成为一项新型的胃癌诊断技术应用于医学领域。%Early diagnosis have great positive effect on the treatment of gastric cancer patients .Raman spectroscopy can provide a useful monitor for hemoglobin dynamics .Besides ,Raman spectroscopy has notable advantages in the fields of abnormal hemo-globin diagnosis ,hemoglobin oxygen saturation deter mination and blood methemoglobin analysis .In this paper ,novel silver colloid was synthesized by microwave heated method .The surface enhanced Raman spectrums of hemoglobin from 11 normal persons and 20 gastric cancer patients are measured and analyzed in order to obtain spectrums which are high repeatability and characteristic peaks protruding .By analyzing the assignations of the SERS bands ,it found that the content of asparagine ,tyro-sine and phenylalanine in the hemoglobin are significantly lower than healthy people .Discussing the structure of hemoglobin , when hemoglobin combines with oxygen ,Fe2+ is in a low spin state ,ionic radius shrinks and moves 0.075 nm and fall into the pore in the middle of the heme porphyrin ring plane .This spatial variation affects F8His connected with the iron ,will narrow the gap between the globin in the two strands of the helix ,as a result ,HC2 tyrosine pushed out of the void .Using this mechanism , the absorption peak of 1 560 cm -1 confirmed that the tyrosine content in patients with gastric cancer was lower than that of nor-mal people .Principal component analysis(PCA) is employed to get a three-dimensional scatter plot of PC scores for the health and cancer groups ,and it can be learned that they are distributed in separate areas .By using the method of discri minate analy-sis ,it is found that the diagnostic algorithm separates the two groups with sensitivity of 90 .0% and diagnostic specificity of 90.9% ,the overall diagnostic accuracy was 90 .3% .The results from this exploratory study demonstrate that ,SERS detection of oxyhemoglobin combined with multivariate analysis would be an effective method for early diagnosis of gastric cancer .
