The multi-walled carbon nanotubes (CNTs) and reduced graphene oxide (rGO) nanosheets were functionalized with 2-hydroxymethyl thiophene (CNT-f-COOTh) and 2-thiophene acetic acid (rGO-f-TAA) and grafted with poly(3-dodecylthiophene) (CNT-g-PDDT and rGO-g-PDDT) to manipulate the orientation and patterning of crystallized regioregular poly(3-hexylthiophene) (P3HT). Distinct nano-hybrid structu...

To amplify the difference in localized surface plasmon resonance (LSPR) spectra of gold nano-islands due to intermolecular binding events, gold nanoparticles were used. LSPR-based optical biosensors consisting of gold nano-islands were readily made on glass substrates using evaporation and heat treatment. Streptavidin (STA) and biotinylated bovine serum albumin (Bio-BSA) were chosen as the mode...

1500 copies of this issue have been printed. This E-Nano newsletter issue is dedicated to present a review on Non-Contact AFM (NC-AFM) and therefore to provide a better understanding on how to image individual molecules, nanostructures, etc. on surfaces with this technique. Patterning of materials on the nanoscale is currently one of the major challenges for Nanotechnology. The research report ...

Understanding the correlation between film structure and its ferromagnetic properties is very important for applications. To this end, we have investigated epitaxial and smooth Ni films grown on MgO substrates using molecular beam epitaxy (MBE) and dc sputtering. To establish correlation between film morphology and structure with magnetic properties, we have used in situ and ex situ scanning tu...

Patterned thin-films of magnetic nanoparticles (MNPs) can be used to make: surfaces for manipulating and sorting cells, sensors, 2D spin-ices and high-density data storage devices. Conventional manufacture of patterned magnetic thin-films is not environmentally friendly because it uses high temperatures (hundreds of degrees Celsius) and high vacuum, which requires expensive specialised equipmen...

Nano-patterning of graphene film by a novel approach making use of laser ablation generated pressure is presented in this paper. Arrays of nanoscale holes were fabricated by applying laser shock pressure on graphene film suspended on well trenches in silicon substrate. Round holes with diameters ranging from 50 to 200 nm on graphene film were successfully punched. The critical pressure was foun...

Weakly charged solid substrates can be nano-patterned in liquid-like order with large and well-defined spacing by adsorbing poly(amido amine) (PAMAM) dendrimers; highly charged substrates lead to lower spacing due to electrostatic three-body attractions between the dendrimers and the substrate.
