Researchers Report Novel Approach for Single Molecule Electronic DNA Sequencing

Sep. 2012- DNA sequencing is the driving force behind key discoveries in medicine and biology. For instance, the complete sequence of an individual’s genome provides important markers and guidelines for medical diagnostics and healthcare. Up to now, the major roadblock has been the cost and speed of obtaining highly accurate DNA sequences. While numerous advances have been made in the last 10 years, ...

High Aspect Ratio Polymer Nanopore Membranes by Conformal Initiated Chemical Vapor Deposition

May. 2011- Recently, Asatekin and Gleason from MIT reported on their work using conformal initiated chemical vapor deposition (iCVD) to control the size and surface functionality of polymeric nanopores. Their work demonstrates a simple, scalable nanomanufacturing process to synthesize nanopore membranes for separation of small molecules. Utilizing a facile approach to tune the pore size, shape, and surface ...

Filling of Nanoporous Electrode Structures for Dye Sensitized Solar Cells by Initiated Chemical Vapor Deposition

Dec. 2010- Nejati and Lau investigate initiated chemical vapor deposition (iCVD) as a solvent-free method to form solid polymers in nanoscale structures, circumventing the challenges of replacing liquid electrolytes with solid state or gel materials in dye sensitized solar cells (DSSCs). 

Nanopatterned Silicon Membranes Provide Stable, Efficient Thermoelectric Properties

Dec. 2010- In order to realize competitive thermoelectric devices from silicon, an approach to synthesize high-density, highly uniform nanostructures must be utilized. Recently, Tang et. al. reported on the thermoelectric performance enhancements in a new type of nanostructured material, holey silicon (HS). In their approach, the authors demonstrate nanostructured silicon membranes that exhibit ~50 ...

Fabrication of a nanoporous template from a diblock copolymer film - electric field alignment

Fabrication of a nanoporous template from a diblock copolymer film - electric field alignment

An applied electric field aligns a cylindrical-phase diblock copolymer perpendicular to a substrate. One polymer block is removed by UV exposure and a chemical rinse to yield a nanoporous polymer film. The porous film can be used as a template for electrodeposition of metal nanowires or as a mask for reactive ion etching.

Fabrication of a nanoporous template from a diblock copolymer film - neutral brush

Fabrication of a nanoporous template from a diblock copolymer film - neutral brush

A perpendicular orientation of cylindrical microdomains in diblock copolymer thin films is achieved by control over polymer-surface interactions. The block which forms cylindrical microdomains is removed by UV exposure and a chemical rinse to yield a nanoporous polymer film. The porous film can be used as a template for electrodeposition of metal nanodots or as a mask for reactive ion etching.

Fabrication of a nanoporous template from a diblock copolymer film - solvent annealing

Fabrication of a nanoporous template from a diblock copolymer film - solvent annealing

An evaporation-induced flow in solvent cast block copolymer films can produce arrays of nanoscopic cylinders oriented normal to the surface and solvent annealing could markedly enhance the ordering of block copolymer microdomains in thin films. Without removing minor components, solvent-induced surface reconstruction can produce nanoporous structure in thin films. The porous film can be used as ...
