【摘要】：多面體低聚倍半硅氧烷(Polyhedral Oligomeric Silsesquioxane,POSS)作為連接有機(jī)材料和無機(jī)材料的重要中間體材料,受到越來越多的關(guān)注。本論文設(shè)計合成了POSS與寡聚苯撐乙烯衍生物(OPVE)雜化共軛水溶性熒光納米顆粒。通過核磁共振譜、飛行時間質(zhì)譜、熱重分析、傅里葉變換-紅外光譜儀、紫外分光光度計、熒光分光光度計、熒光壽命譜儀、透射電子顯微鏡、動態(tài)光散射粒徑-電位測量儀對納米粒子的分子結(jié)構(gòu),物理性能,熱性能,光學(xué)性能,電致發(fā)光性能的表征,反映出POSS-OPVE良好的水溶性、光穩(wěn)定性、熱穩(wěn)定性、生物相容性、抗氧化性、強(qiáng)度以及低毒性等。本論文對于POSS-OPVE納米粒子的在納米生物領(lǐng)域的應(yīng)用,主要包括以下幾個方面內(nèi)容:1,POSS-OPVE應(yīng)用于大腸桿菌微生物燃料電池,作為電子運輸?shù)拿浇轶w,可以使MFC產(chǎn)生的電壓增加,功率提高。并且通過與同類已知共軛寡聚電解質(zhì)的對照試驗我們得知了POSS-OPVE在產(chǎn)電方面比其更有效。顯示了POSS-OPVE等有機(jī)-無機(jī)雜化材料在作為微生物燃料電池媒介體方面提高產(chǎn)電效能方面具有很大潛能。2,POSS納米顆粒應(yīng)用于脂多糖(LPS)的檢測,由于兩者之間的靜電吸引相互作用以及有機(jī)憎水部分相互排斥作用,觀察到POSS-OPVE熒光增強(qiáng)且藍(lán)移,成功地將POSS-OPVE用于革蘭氏陰性細(xì)菌細(xì)胞膜的特異性識別物L(fēng)PS以及的檢測,最高靈敏度可達(dá)23 n M。并把其應(yīng)用革蘭氏陰性菌的染色鑒別。
[Abstract]:Polyhedral Oligomeric Silsesquioxaneus POSS (polyhedron oligosilane) is an important intermediate material for connecting organic and inorganic materials. In this paper, the conjugated conjugated water-soluble fluorescent nanoparticles of POSS and OPVE were designed and synthesized by NMR, time-of-flight mass spectrometry (TMS), thermogravimetric analysis (TGA), Fourier transform infrared spectrometer (FTIR), Fourier transform infrared spectroscopy (FTIR), Fourier transform infrared spectroscopy (FTIR). UV Spectrophotometer, fluorescence Spectrophotometer, fluorescence Lifetime Spectrometer, Transmission Electron microscope, dynamic Light scattering Particle size potentiometer, Molecular structure, physical Properties, Thermal Properties, Optical Properties of nanoparticles, The characterization of electroluminescent properties shows that POSS-OPVE has good water-solubility, photostability, thermal stability, biocompatibility, oxidation resistance, strength and low toxicity. The main contents include the following aspects: 1 / 1 POSS-OPVE applied to E. coli microbial fuel cells, as an electronic transport medium, can increase the voltage generated by MFC. Power increase. And through the control test with the same kind of known conjugated oligoelectrolytes, we know that POSS-OPVE is more effective than it in producing electricity. It shows that POSS-OPVE and other organic-inorganic hybrid materials are used as microbial fuel cell vectors. In terms of improving the efficiency of electricity production, it has great potential to be used in the detection of lipopolysaccharide (LPSs) by using poss nanoparticles. Due to the electrostatic attraction interaction and the repulsion of organic hydrophobicity, POSS-OPVE fluorescence was enhanced and blue shift was observed. POSS-OPVE was successfully used in the detection of LPS, a specific cell membrane recognizer of Gram-negative bacteria. The highest sensitivity was up to 23 n M. the method was applied to the identification of Gram-negative bacteria.
