Fe3O4/Au是结合胶体金和磁性纳米粒子双重优势的新型复合材料,本团队在全球率先开展Fe3O4/Au复合微粒的研究(Y.Cui,et.al.,Science in China(Series B),44(4):404～410,2001)并将其命名为GoldMag(R)金磁微粒(Y.Cui et.al.,Biomedical Microdevices 7:2,153～156,2005).
在毛细管和微流控芯片电泳分析中,由于检测窗口过于细小而不利于光学检测,其检测灵敏度通常只能达到10-9 mol/L 左右.但是许多疾病,特别是重大疾病如肿瘤在其发病的初级阶段,疾病标志物的含量非常低,采用目前的毛细管电泳和微流控芯片电泳方法检测,由于灵敏度不够而出现假阳性,难以得到准确的测定结果.因此,发展超高灵敏的微尺度分离分析新技术,实现对生物样品中痕量疾病标志物的检测,是疾病的早期预警和准确
肝细胞肝癌(HCC)在世界范围内发病率和死亡率分别居恶性肿瘤的第5位和第3位.目前我国肝癌的发病人数占全球的55 ％,其死亡率排在恶性肿瘤的第二位,但是目前仍缺少肝癌早期诊断的一个高检出率的指标,进行肝癌代谢组研究并发现肝癌早期诊断的生物标记物是一个非常有挑战和意义的课题.
逆流色谱(Counter-current chromatography,CCC)技术是20世纪由Ito Yoichiro 等人发明的一种液-液分配色谱技术[1,2].后来,Ito[3]等人利用螺旋管同步行星式运动所产生的变化离心离场将固定相保留在螺旋管内,流动相快速的流过螺旋管与固定相进行连续高效的混合和分配,可以实现样品的快速分离和制备,开发了目前广泛应用的高速逆流色谱( High speed
鸟枪法是目前蛋白质组分离鉴定应用最广泛的策略.然而,蛋白质组样品的高复杂性、宽动态范围分布使得低丰度肽段以及难离子化肽段的质谱检测仍旧面临着巨大挑战.本文以理论化学辅助设计为基础,合成了三种新型咪唑类芳香季铵衍生化试剂,包括溴化1-[3-[(2-碘-1-氧乙基)氨基]丙基]-3-甲基咪唑(IPMI),溴化1-[3-[(2-碘-1-氧乙基)氨基]丙基]-3-丁基咪唑(IPBI)和溴化1-[3-[(2
3 micro class ultrafast lasers have aroused considerable attention due to their potential applications in mid-infrared spectroscopy,laser surgery,and many nonlinear applications.
We present an all-fiber linear polarized actively mode-locked thulium-doped fiber laser operating at 2 μm.Without altering system configuration of this fiber laser,we also obtained polarized harmonic
Quitting smoking is one of the best things people can do for their health.While there are many ways you can stop smoking,many people turn to the newest substitute for tobacco:electronic cigarette.But,
On the basis of our recent work [1–3] we analyse the new exact solutions of the relativistic wave equations of a charged particle interacting with an arbitrary high-amplitude monochromatic radiation,w
For many years,several attempts have been made to enhance skin permeability by chemical,physical or mechanical manipulations to reduce the barrier function of the skin.The present study demonstrates t
