層層自組裝(layer by layer self-assembly，LbL)是一種重要的薄膜制備技術(shù)，它具有組裝基元和驅(qū)動(dòng)力多樣、操作簡(jiǎn)單、條件溫及可在非平面上制備等諸多優(yōu)點(diǎn)。在膜分離、催化、生物傳感器以及抗感染方面有著重要的應(yīng)用價(jià)值。特別是具有抗菌型的多層膜在生物醫(yī)用材料抗感染方面的應(yīng)用越來(lái)越受到人們的關(guān)注，具有潛在的研究?jī)r(jià)值。 本文將釓-諾氟沙星(Gd-NFLX)分別與Dawson結(jié)構(gòu)鎢磷酸鹽(P2W18)、一缺位Dawson結(jié)構(gòu)釩取代磷鎢酸鹽(P2W17V)、二缺位Dawson結(jié)構(gòu)釩取代磷鎢酸鹽(P2W16V2)、夾心結(jié)構(gòu)銅修飾銻鎢酸鹽(SbW9Cu3) 、夾心結(jié)構(gòu)銅修飾鉍鎢酸鹽(BiW9Cu3)交替沉積制備多層抗菌膜，并對(duì)薄膜性質(zhì)進(jìn)行了研究。具體內(nèi)容如下： (2) 以層層自組裝技術(shù)制備了P2W17V/Gd-NFLX多層膜，利用紫外跟蹤了膜的增長(zhǎng)過(guò)程，并對(duì)薄膜的抗菌效果、電化學(xué)性質(zhì)、熒光性質(zhì)、表面形貌以及膜的穩(wěn)定性進(jìn)行了系列的研究。研究結(jié)果表明：薄膜具有很好的光滑度透明度，同時(shí)呈現(xiàn)出優(yōu)異的電化學(xué)性能和抗菌性能，對(duì)大腸桿菌殺菌持久，殺菌率高達(dá)99%，另外薄膜在0~100℃范圍內(nèi)非常穩(wěn)定，而薄膜中的Gd-NFLX被P2W17V猝滅。 [ Last edited by lize886622 on 2013-2-17 at 15:36 ] |

Layer by layer self-assembly (LbL) is an important film preparation technique. It has lots of advantages such as the diversity of assembly primitives and driving force, the simple operation, and possible preparation on non-planar plate. Hence it is of great applications in field of membrane separation, catalysis, biosensors, and anti-infective. Especially, more and more attention has been paid to its potential application in biomedical materials with antibacterial multilayer film resistance to infection. In this paper, Gadolinium-norfloxacin (Gd-NFLX) was combined with some other materials by alternately deposition to prepare the antibacterial multilayered films and their properties were studied. These materials include the tungsten phosphate with dawson structure (P2W18), vanadium replaced phosphorus tungstate with dawson structure (P2W17V), vanadium substituted phosphortungstate with dawson structure (P2W16V2), the copper modified antimony tungstate with sandwich structure (SbW9Cu3), the copper modified bismuth tungstate with sandwich structure (BiW9Cu3), The specific contents are as follows: (2) P2W17V/Gd-NFLX multilayers has been prepared by self-assembly technique. The antimicrobial effect, the electrochemical and fluorescence properties, surface morphology, and membrane stability of the layers has been systematically investigated by tracking the growth process of the film using UV technique. It reveals that the film is of great transparency and smoothness, while presents excellent electrochemical performance and antimicrobial performance. It could do lasting sterilization against Escherichia coli, and the sterilization rate is up to 99%. Moreover, such film is very stable within the temperature range of 0 ~ 100 ℃, but the Gd-NFLX was quenched by P2W17V in this film. 看沒(méi)人幫你，你就將就吧，僅供參考。  |
