Nano-Biotechnology toward Diagnostic Industry: Obstacles and Opportunities

Biosensing of infectious agents should be ideally real-time, multiplexed, sensitive and specific. While no single device thus far have demonstrated superiority with respect to all these qualities, many of the upcoming nanomaterial-based sensors described in [...]

Serpentine Fluidic Structures for Particle Separation

Kole A.S., Lean M.H., Seo J., Palo Alto Research Center Inc, US

The above abstract is based on a novel technique for particle separation from liquid based solely on fluidic forces on the particles. No external force or filters are used for separation. The idea is scalable [...]

Fabrication of Perforated Membranes in Polymers by Imprint Lithography

Roychowdhury A., Park S., Louisiana State University, US

The ability to imitate architecture of naturally existing systems in an economical way is important because this will provide platform for various fundamental and applied research activities. One such structure is a perforated membrane having [...]

Assemblies of Blue-emitting CdSe Nanocrystals in Redox Copper Phenanthroline-based Polymeric Chains

Fu S.-J., Lin K.-J., National Chung Hsing University, TW

Assemblies of quantum-confined semiconductor nanoparticles into block copolymer micelles and silica shell open the door to “tunable” optical, electrical, and even mechanical properties. Sharp tuning of 3D spherical morphology in water solution is a fascinating [...]

Development of a Mobile Asbestos Decontamination Process

Gerdes T., Rosin A., Willert-Porada M., University of Bayreuth, DE

Within the European project “New Safe and Cost Effective Techniques Against Asbestos Risks” different methods for decontamination of asbestos in asbestos containing wastes, abbreviated as ACW from building industry were investigated. A mobile asbestos decontamination [...]

Nanostructuration of sol-gel thin films

Peroz C., Goletto V., Foresti M., Heitz C., Le Gratiet L., Barthel E., Sondergard E., Laboratoire mixte CNRS/Saint-Gobain, FR

Sol-gel chemistry is very versatile and structuring sol-gel materials will allow a fine tuning of chemistry, electromagnetic, optical and mechanical properties. We explore the possibilities to combine sol-gel chemistry to large scale patterning at low [...]

Transforming nano-science to nano-technology: Manipulating the size, shape, surface morphology, agglomeration, phases and defects of silver nano-particles under continuous flow conditions

Iyer S., Raston C.L., Saunders M., The University of Western Australia, AU

Spinning disc processing (SDP) is an instantaneously scalable, continuous flow and high throughput flash nano-fabrication technology which embraces green chemistry metrics. It has been used to prepare silver nano-particles with remarkable control in size (5 [...]

Study of model contaminants desorption from recycled PET in dry air and nitrogen atmosphere by thermogravimetric analysis

Santos A.S.F., Agnelli J.A.M., Medeiros E.S., Corradini E., Manrich S., Institute for Technological Research, BR

The polyethylene terephthalate (PET) bottle-to-bottle recycling is a good example of a successful technology that has allowed an increase of recycled plastic market. Nevertheless, the capability of all these processes to decontaminate recycled plastics into [...]

Nanoimprint Mold Manufacturing with Focused Ion Beam

Chung M., Huang B.R., Weng M.H., Fu C.S., Chang Y.Y., Lai S.W., Chiou J.M., Chen Y-C, Tzeng Y.H., Southern Taiwan University of Technology, TW

Nanoimprint lithography (NIL) is an emerging low cost technique for reproducing sub-100 nm pattern in various applications; however, manufacturing the mold for nanoimprint has been a key issue both in expense and resolution. Focused Ion [...]

Poly(acrylic) acid-coated Silver Nanoparticles for Antibacterial Textile Finishing

Falletta E., Bonini M., Fratini E., Lo Nostro A., Lo Nostro P., Becheri A., Lo Nostro A., Lo Nostro P., Baglioni P., University of Florence, IT

The synthesis of silver nanoparticles was obtained through two different methods and using different poly(acrylic) acids as templating agents. Cotton, wool, and polyester fabrics were treated with the nanoparticles, and their antimicrobial performances were tested [...]
