Conducting Polymer Enzyme Alloys: Electromaterials Exhibiting Direct Electron Transfer

MACROMOLECULAR RAPID COMMUNICATIONS, Issue 14 2010
Brianna C. Thompson
Abstract Glucose oxidase (GOx) is an important enzyme with great potential application for enzymatic sensing of glucose, in implantable biofuel cells for powering of medical devices in vivo and for large-scale biofuel cells for distributed energy generation. For these applications, immobilisation of GOx and direct transfer of electrons from the enzyme to an electrode material is required. This paper describes synthesis of conducting polymer (CP) structures in which GOx has been entrained such that direct electron transfer is possible between GOx and the CP. CP/enzyme composites prepared by other means show no evidence of such "wiring". These materials therefore show promise for mediator-less electronic connection of GOx into easily produced electrodes for biosensing or biofuel cell applications. [source]

Stable, Glassy, and Versatile Binaphthalene Derivatives Capable of Efficient Hole Transport, Hosting, and Deep-Blue Light Emission

Abstract Organic light-emitting diodes (OLEDs) have great potential applications in display and solid-state lighting. Stability, cost, and blue emission are key issues governing the future of OLEDs. The synthesis and photoelectronics of a series of three kinds of binaphthyl (BN) derivatives are reported. BN1,3 are "melting-point-less" and highly stable materials, forming very good, amorphous, glass-like films. They decompose at temperatures as high as 485,545,°C. At a constant current density of 25,mA,cm,2, an ITO/BN3/Al single-layer device has a much-longer lifetime (>80,h) than that of an ITO/NPB/Al single-layer device (8,h). Also, the lifetime of a multilayer device based on BN1 is longer than a similar device based on NPB. BNs are efficient and versatile OLED materials: they can be used as a hole-transport layer (HTL), a host, and a deep-blue-light-emitting material. This versatility may cut the cost of large-scale material manufacture. More importantly, the deep-blue electroluminescence (emission peak at 444 nm with CIE coordinates (0.16, 0.11), 3.23 cd A,1 at 0.21,mA cm,2, and 25200,cd,m,2 at 9,V) remains very stable at very high current densities up to 1000,mA,cm,2.

Down- and Up-Conversion Luminescent Nanorods,

ADVANCED MATERIALS, Issue 20 2007
L. Wang
With a facile one-pot strategy, up-conversion and down-conversion luminescent LaF3 and NaLaF4 nanorods are successfully prepared. Owing to their high up-conversion and down-conversion luminescence, ease of processing, and simple fabrication, these luminescent inorganic nanocrystals may find great potential applications in polymer-based devices.

Core/shell pH-sensitive micelles self-assembled from cholesterol conjugated oligopeptides for anticancer drug delivery

AICHE JOURNAL, Issue 7 2010
Xin Dong Guo
Abstract A doxorubicin (DOX) delivery system of pH-sensitive micelles self-assembled from cholesterol conjugated His5Arg10 (HR15-Chol) and His10Arg10 (HR20-Chol) has been described in this article. The amphiphilic molecules have low critical micelle concentrations of 17.8 and 28.2 ,g/mL for HR15-Chol and HR20-Chol, respectively, even at a low pH of 5.0. The pH-sensitive histidine segment of the polypeptide block is insoluble at pH 7.4 but becomes positively charged and soluble via protonation at pH lower than 6.0. The size and zeta potential of DOX-loaded micelles increases with the decrease in pH. Coarse-grained simulations were performed to verify the structure of DOX-loaded micelles and pH sensitivity of HR15/20-Chol. The in vitro DOX release from the micelles is significantly accelerated by decreasing pH from 7.4 to 5.0. Furthermore, DOX release from the micelles is controlled by a Fickian diffusion mechanism. These micelles have great potential applications in delivering hydrophobic anticancer drugs for improved cancer therapy. © 2009 American Institute of Chemical Engineers AIChE J, 2010 [source]
