  • Supramolecular Assemblies of Functional Nanoporphyrins in Therapeutics

    New supramolecular systems have been assembled with the use of bridging unities such as tetrapyridylporphyrins, porphyrazines and polypyrazines. The assembly involves the orientation of the pi-conjugated rings, which are kept together by means of strong hydrophobic intermolecular interactions, as well as by the electrostatic interactions between the peripheral cationic and anionic residues. The porphyrins and ruthenium polypyridines are two classes of compounds exhibiting most of the above mentioned molecular properties. In the present study new cationic porphyrin as tetraruthenium (bipyridine)porphyrin (4+)(TRPyP) was synthesized and its association with anionic porphyrin (TSPP) forming heteroaggregates, is investigated. Potential applications in photodynamic therapy of cancer are discussed.

  • A high-flow Knudsen pump using a polymer membrane: Performance at and below atmospheric pressures

    This paper describes a miniature gas (Knudsen) pump that utilizes thermomolecular flow through a nanoporous membrane. A temperature gradient along the length of a pore that supports free molecular gas flow at atmospheric pressure pumps gas molecules from the cold end to the hot end. In contrast with past work, the membrane material is mixed cellulose which provides superior uniformity in pore diameter and porosity. The final packaged volume of the Knudsen pump is 14×14×4.4 mm<sup>3</sup>. For an input power of 1.4 W, a single stage Knudsen pump based on these nanoporous polymer membrane has a temperature bias of 30 K across the thickness of the membrane, which provides 0.4 sccm flow against a 330 Pa pressure head. The load characteristics of the pump suggest that the pump can provide as much as 0.93 sccm gas flow in the absence of a load. Knudsen pump operation at sub- atmospheric pressures is also reported.

  • Improvements of silicon integrated GOx micro enzyme reactors by the use of porous silicon as a surface enlarging matrix

    Micro flow-through cells were fabricated in silicon and were designed to work as micro enzyme reactors (columns) for glucose monitoring. The reactor design comprised a parallel channel structure with 32 channels, 50 /spl mu/m wide. A reactor with vertical channels yields a much larger surface area than a corresponding v-groove channel structure. Therefore, [110] silicon was used to allow the fabrication of channels with vertical walls (channel depth was 250 /spl mu/m). Glucose oxidase (GOx) can be immobilized to the silicon surface and earlier measurements have shown that the increase in enzyme activity corresponded to the surface area increase of such a channel structure. A new approach to surface enlargement was investigated. Planar silicon surfaces were anodised in an HF/ethanol etchant, yielding a spongious nanoporous silicon surface. Dice with three different porosities were fabricated and GOx was coupled to the porous dice. The increase in enzyme activity due to surface enlargement of the nanoporous structure was 33 times compared to a planar surface. The two surface enlarging strategies (vertical channel reactors and porous silicon) were subsequently combined, giving a parallel vertical channel structure covered by a porous silicon layer. This reactor structure displayed an enzyme activity increase of 100 times when compared to a non-porous channel structure.

  • Cellular responses to nanotopology of polymeric surfaces fabricated with AAO nanoimprinting

    We made various patterns on the PMMA surfaces and observed the cellular responses on them. Nanoimprinting using AAO (anodized aluminum oxide) template was used for the topology control of polymeric culture surfaces. AAO has numerous regularly-spaced nanopores. The pore diameter and the center-to- center pore distance can be easily controlled by altering the anodizing and etching conditions. One of the main advantages of using AAO as a template in nanoimprinting is that nanometer-scale structure templates larger than 25 cm/sup 2/ are easily, economically and quickly fabricated, which are suitable for various cellular studies. We cultured fibroblast on the variously nanopatterned surfaces directly or after surface treatment with collagen, O/sub 2/ plasma, or both. The cellular activities of fibroblasts on 420 nm- nodule pattern treated with both were significantly retarded at 24 hours. Fibroblasts also showed significantly different activities among different patterns. In the time-lapse observation of initial adhesion in stressed condition (ambient temperature and no CO/sub 2/ supply) from 3.5 hours to 5.5 hours after seeding, we could conclude that fibroblast do not like 420 nm- nodule pattern for their initial adhesion as fibroblasts on 420 nm-nodule pattern markedly changed their shape to round form while those on 90 nm-nodule pattern maintained their shape.

  • Synthesis of MoS/sub 2/ nanostructures from nano-size powder by thermal annealing

    It have been shown that the molybdenite could be the first inorganic fullerene-style molecular shell (MoS/sub 2/)n, of perhaps several materials, based on the transition metal chalcogenides, which could be allowed to create nanocages and nanotubes. We first describe in detail the attempt to produce nanostructures from nano-size MoS/sub 2/ powder by thermal annealing in vacuum conditions. We show the chemical synthesis process of nano-size MoS/sub 2/ powder and the technological regimes of thermal treatment of molybdenite nano- size powder. The TEM images of thermal treated molybdenite powder show the appearance of curvature of reflective planes [002], which could be considered as initial seeds for nanostructures.

  • Forming low resistance nano-scale contacts using solder reflow

    We describe the use of solder reflow on the 100 nanometer scale to form electrically conductive contacts. We fabricated nanowires using electrodeposition in nanoporous templates. We investigated the use of directed assembly and nanoscale soldering to integrate the nanowires with microfabricated bond pads, and measured the electrical characteristics of the soldered wires. The electrical resistance of a single nanowire on top of two adjacent contact pads dropped by an order of magnitude after solder reflow. The results in this paper demonstrate that it is possible to use solder films as thin as 100 nm to electrically bond nanocomponents to substrates with contact resistances as low as 5 /spl Omega/.

  • Preliminary study on dependency of basic properties of porous silica ILD thin film on CMP compatibility

    Adhesion, cohesive strength, modulus, and hardness of the porous silica ILD film via organic/inorganic hybrid (ALCAP-S) with various kinds of film thickness were investigated and the preliminary attempt was made to correlate the above properties with abrasion compatibility as a function of film thickness. The Stud-pull strength is drastically affected by the visco-elastic behavior of the film and necessary for correction. The corrected adhesion and cohesive strength of ALCAP-S (k=2.2) are satisfactorily high. With decreasing the film thickness, the depth-dependency of modulus induced by the substrate becomes more significant and the corresponding film is liable to abrasion. On the contrary, with increasing thickness the dependency ceases and the film appears to be more elastic, leading to lower abrasion compatibility.

  • Physical considerations of operating and characteristics modeling of nanostructural field emission devices

    In this paper, the characteristics of nanostructural field emission devices (FEDs) are determined based on a basic model that is a field emission triode cell which has more complicated structure compared with a diode. The basic elements of a field emission triode cell was characterized using the following parameters; conductor elements, dielectric elements, the boundary of a field emission triode cell, and an electron gas region or vacuum region. Physical processes was described by means of the fundamental equations of Maxwell, Fowler-Nordheim and hydrodynamical equations describing the behaviour of electron gas.

  • Ultrafast optical Kerr effect spectroscopy of water confined in nanopores of the gelatin gel

    This paper reports on the investigation of the water structure in the pores of the gelatin gel, gelatin being the biopolymer obtained by denaturation of collagen, in times shorter than the lifetime of molecular complexes. This study utilizes the femtosecond optical Kerr-effect spectroscopy with heterodyne detection, by use of Ar-ion laser pumped sapphire laser with 40 fs pulse duration. The ultrafast responses of water molecules, obtained in bulk liquid and in two concentrations of gelatin gels are shown. Significant changes can be seen in the intermediate-time region, which results from the intermolecular collective vibrations of molecular clusters.
