Nanofabrication of Gate-defined GaAs/AlGaAs Lateral Quantum Dots

1Département de Physique, Faculté des Sciences, Université de Sherbrooke


JoVE 50581

This paper presents a detailed fabrication protocol for gate-defined semiconductor lateral quantum dots on gallium arsenide heterostructures. These nanoscale devices are used to trap few electrons for use as quantum bits in quantum information processing or for other mesoscopic experiments such as coherent conductance measurements.

Capillary Force Lithography for Cardiac Tissue Engineering

1Department of Bioengineering, University of Washington, 2Department of Pathology, University of Washington


JoVE 50039

In this protocol, we demonstrate the fabrication of biomimetic cardiac cell culture substrata made from two distinct polymeric materials using capillary force lithography. The described methods provide a scalable, cost-effective technique to engineer the structure and function of macroscopic cardiac tissues for in vitro and in vivo applications.

Formation of Biomembrane Microarrays with a Squeegee-based Assembly Method

1Department of Electrical and Computer Engineering, University of Minnesota, 2Department of Biomedical Engineering, University of Minnesota, 3Department of Neurology, Mayo Clinic College of Medicine, 4Department of Immunology, Mayo Clinic College of Medicine


JoVE 51501

Supported lipid bilayers and natural membrane particles are convenient systems that can approximate the properties of cell membranes and be incorporated in a variety of analytical strategies. Here we demonstrate a method for preparing microarrays composed of supported lipid bilayer-coated SiO2 beads, phospholipid vesicles or natural membrane particles.

Fabrication of Carbon Nanotube High-Frequency Nanoelectronic Biosensor for Sensing in High Ionic Strength Solutions

1Department of Electrical Engineering and Computer Science, University of Michigan - Ann Arbor


JoVE 50438

We describe the device fabrication and measurement protocol for carbon nanotube based high frequency biosensors. The high frequency sensing technique mitigates the fundamental ionic (Debye) screening effect and allows nanotube biosensor to be operated in high ionic strength solutions where conventional electronic biosensors fail. Our technology provides a unique platform for point-of-care (POC) electronic biosensors operating in physiologically relevant conditions.

In Situ SIMS and IR Spectroscopy of Well-defined Surfaces Prepared by Soft Landing of Mass-selected Ions

1Physical Sciences Division, Pacific Northwest National Laboratory


JoVE 51344

Soft landing of mass-selected ions onto surfaces is a powerful approach for the highly-controlled preparation of novel materials. Coupled with analysis by in situ secondary ion mass spectrometry (SIMS) and infrared reflection absorption spectroscopy (IRRAS), soft landing provides unprecedented insights into the interactions of well-defined species with surfaces.

Ultrahigh Density Array of Vertically Aligned Small-molecular Organic Nanowires on Arbitrary Substrates

1Electrical and Computer Engineering, University of Alberta


JoVE 50706

We report a simple method for fabricating an ultrahigh density array of vertically ordered small-molecular organic nanowires. This method allows for synthesis of complex heterostructured hybrid nanowire geometries, which can be inexpensively grown on arbitrary substrates. These structures have potential applications in organic electronics, optoelectronics, chemical sensing, photovoltaics and spintronics.

Fabrication of Spatially Confined Complex Oxides

1Materials Science and Technology Division, Oak Ridge National Laboratory, 2Department of Physics & Astronomy, University of Tennessee, Knoxville


JoVE 50573

We describe the use of pulsed laser deposition (PLD), photolithography and wire-bonding techniques to create micrometer scale complex oxides devices. The PLD is utilized to grow epitaxial thin films. Photolithography and wire-bonding techniques are introduced to create practical devices for measurement purposes.

Origami Inspired Self-assembly of Patterned and Reconfigurable Particles

1Department of Chemical and Biomolecular Engineering, The Johns Hopkins University, 2Department of Chemistry, The Johns Hopkins University


JoVE 50022

We describe experimental details of the synthesis of patterned and reconfigurable particles from two dimensional (2D) precursors. This methodology can be used to create particles in a variety of shapes including polyhedra and grasping devices at length scales ranging from the micro to centimeter scale.

Fabricating Nanogaps by Nanoskiving

1Stratingh Institute for Chemistry and Zernike Institute for Advanced Materials, University of Groningen


JoVE 50406

The fabrication of electrically addressable, high-aspect-ratio (> 1000:1) metal nanowires separated by gaps of single nanometers using either sacrificial layers of aluminum and silver or self-assembled monolayers as templates is described. These nanogap structures are fabricated without a clean room or any photo- or electron-beam lithographic processes by a form of edge lithography known as nanoskiving.
