摘要： The present invention provides electrodes comprised of metal-coated vertically aligned carbon nanofibers. Arrays of vertically aligned carbon nanofibers provide highly accessible, high density templates having large electrochemically active surface areas that may be modified to further increase the surface area of the nanofibers. The methods of the present invention involve functionalizing the surface of the nanofibers and coating the functionalized surface with metal using electroless deposition. The resulting metal-coated nanofibers form highly stable and highly reproducible electrodes having very high surface areas. The electrodes of the present invention are expected to be useful in a variety of applications, including high-density energy storage, i.e., supercapacitors and fuel cells.

摘要： Disclosed herein are methods for functionalizing metal oxides, including tin dioxide. The methods comprise contacting at least one linker precursor comprising a first functional group to a metal oxide and exposing the linker precursor to UV light. The first functional group covalently binds to the metal oxide via a UV light induced reaction. The linker precursor may be an alkene having a vinyl group or an alkyne having an ethynyl group. Other molecules, such as biomolecules and dye molecules, may be bound to the linker precursors. The functionalized metal oxides may be used alone or as coatings on a substrate and find use in a variety of devices, including biosensors and dye sensitized solar cells.

摘要： Methods for building sensor arrays using electrical signals to selectively functionalize individual electrodes in an array of electrically addressable electrodes are provided. These methods are useful for providing sensor arrays for use in chemical and biochemical assays. The method is based on the sequential electrochemical reduction of functional groups on individual electrodes in order to selectively promote the functionalization of selected electrodes with selected binding entities.

摘要： Radio-frequency (RF) excitation is used for direct detection of hybridization events at microelectrodes with surface-attached DNA oligomers. A homodyne reflectometer operates on a high frequency carrier to detect the presence of a low-frequency modulation signal. Without non-linearities in an interface, the modulation signal is not impressed upon the carrier signal. As such, the reflectometer can sensitively measure changes in dielectric properties without interference from other sources of capacitance/resistance unrelated to the reaction at the surface.
摘要翻译： 射频（RF）激发用于直接检测具有表面附着DNA寡聚物的微电极杂交事件。 零差反射计在高频载波上工作以检测低频调制信号的存在。 在接口没有非线性的情况下，调制信号不会对载波信号施加影响。 因此，反射计可以敏感地测量介电性能的变化，而不受来自与表面反应无关的其他电容/电阻源的干扰。

摘要： Chemically-modified surfaces on unoxidized carbon, silicon, and germanium substrates are disclosed. Ultraviolet radiation mediates the reaction of protected &ohgr;-modified, &agr;-unsaturated aminoalkenes (preferred) with hydrogen-terminated carbon, silicon, or germanium surfaces. Removal of the protecting group yields an aminoalkane-modified silicon surface. These amino groups can be coupled to terminal-modified oligonucleotides using a bifunctional crosslinker, thereby permitting the preparation of modified surfaces and arrays. Methods for controlling the surface density of molecules attached to the substrate are also disclosed.

摘要： Systems and methods for fabricating ordered anisotropic organic monolayers are described. An apparatus includes a substrate including a surface; and an ordered organic monolayer chemically bonded to the surface, the ordered organic monolayer including a plurality of cyclic organic molecules, each of the plurality of cyclic organic molecules being obtained from an unsaturated cyclic organic reactant that is chemically bonded to the surface through an addition reaction. The systems and methods provide advantages in that translational and rotational order from the substrate is extended into the monolayer.

摘要： SPR-compatible substrates for high density microarray fabrication and analyses are provided. Novel carbon-on-metal thin film substrate architecture permits the integration of surface plasmon resonance detection with photolithographically fabricated biomolecule arrays for the analysis of biomolecular interactions. The utility of the technology is shown in the analysis of specific DNA-DNA, DNA-RNA and DNA-protein binding interactions. These new substrates may be used to determine the secondary structure of RNA molecules, to probe the sequence-specific binding kinetics and affinity of proteins and small molecules, and as substrates for small-molecule combinatorial chemistry platforms for drug discovery applications.
