Challenges for Nanomechanics of Biological Systems
NNI Interagency Workshop : Instrumentation and Metrology for Nanotechnology Grand Challenge Workshop National Institute of Standards and Technology, Gaithersburg, MD Jan 27-29, 2004 Challenges for Nanomechanics of Biological Systems Christine Ortiz, Assistant Professor Massachusetts Institute of Technology Department of Materials Science and Engineering WWW : http://web.mit.edu/cortiz/www/ Biological systems are one of the most difficult classes of materials to study mechanically at the nanoscale.1-3 Their complex multilevel and multicomponent structures (e.g. tissues, cells, proteins) need to be highly purified and characterized with minimal sample preparation damage (if possible, with no polishing and chemical treatments) so as to still give information relevant to in vivo function. Nanomechanical testing can be challenging due to the need for near-physiological conditions (i.e. aqueous salt solutions, ionic strength=0.15M, pH=7.4), the existence of varied 3-dimensional geometries and multiple buried interfaces, and their dynamic and sometimes, extremely soft, fluid-like nature. Following is a summary of a few new areas which I believe represent the most significant new paths in this field. I. Integration of Nanomechanical Testing Methods with Nanoscale Chemical/Structural Characterization Techniques Down to the Single Molecule Level in Near-Phys iological Conditions. One promising example of this is the combination of atomic force microscopy (AFM) and surface enhanced Raman spectroscopy (SERS)(Figure 1).4-8 SERS is a higher resolution version of traditional Raman spectroscopy, in which the wavelength and intensity of inelastically scattered light from molecules is measured. These wavelengths are shifted from the incident light by the energies of molecular vibrations and hence, allow for chemical identification and characterization of substances. -
Engineered Carbon Nanotubes and Graphene for Nanoelectronics And
Engineered Carbon Nanotubes and Graphene for Nanoelectronics and Nanomechanics E. H. Yang Stevens Institute of Technology, Castle Point on Hudson, Hoboken, NJ, USA, 07030 ABSTRACT We are exploring nanoelectronic engineering areas based on low dimensional materials, including carbon nanotubes and graphene. Our primary research focus is investigating carbon nanotube and graphene architectures for field emission applications, energy harvesting and sensing. In a second effort, we are developing a high-throughput desktop nanolithography process. Lastly, we are studying nanomechanical actuators and associated nanoscale measurement techniques for re-configurable arrayed nanostructures with applications in antennas, remote detectors, and biomedical nanorobots. The devices we fabricate, assemble, manipulate, and characterize potentially have a wide range of applications including those that emerge as sensors, detectors, system-on-a-chip, system-in-a-package, programmable logic controls, energy storage systems, and all-electronic systems. INTRODUCTION A key attribute of modern warfare is the use of advanced electronics and information technologies. The ability to process, analyze, distribute and act upon information from sensors and other data at very high- speeds has given the US military unparalleled technological superiority and agility in the battlefield. While recent advances in materials and processing methods have led to the development of faster processors and high-speed devices, it is anticipated that future technological breakthroughs in these areas will increasingly be driven by advances in nanoelectronics. A vital enabler in generating significant improvements in nanoelectronics is graphene, a recently discovered nanoelectronic material. The outstanding electrical properties of both carbon nanotubes (CNTs) [1] and graphene [2] make them exceptional candidates for the development of novel electronic devices. -

License and terms: see end of document. Abstract Nanoscale research of bulk solid surfaces, thin films and micro- and nano-objects has shown that mechanical properties are enhanced at smaller scales. Experimental studies that directly compare local with global deformation are lacking. In this research, spherical Au nanoparticles, 500 nm in diameter and 100 nm thick Au films were selected. Nanoindentation (local deformation) and compression tests (global deformation) were performed with a nanoindenter using a sharp Berkovich tip and a flat punch, respec- tively. Data from nanoindentation studies were compared with bulk to study scale effects. Nanoscale hardness of the film was found to be higher than the nanoparticles with both being higher than bulk. Both nanoparticles and film showed increasing hardness for decreasing penetration depth. For the film, creep and strain rate effects were observed. In comparison of nanoindentation and compression tests, more pop-ins during loading were observed during the nanoindentation of nanoparticles. -

“Nanomechanics: Elasticity and Friction in Nano-Objects”
“NanoMechanics : Elasticity and Friction in Nano-Objects” Start Date: August 2006 Applicant: Elisa Riedo Institution: Georgia Institute of Technology PI: Elisa Riedo Address: School of Physics, 837 State St, Atlanta GA 30332-0430Email: [email protected] DOE Division of Materials Sciences and Engineering, Office of Basic Energy Sciences Mechanical Behavior and Radiation Effects Program DOE Office of Science Program Manager Contact: John S. Vetrano 1. Introduction Nanosheets, nanotubes, nanowires, and nanoparticles are gaining a large interest in the scientific community for their exciting properties, and they hold the potential to become building blocks in integrated nano-electronic and photonic circuits, nano-sensors, batteries electrodes, energy harvesting nano-systems, and nano-electro-mechanical systems (NEMS). While several experiments and theoretical calculations have revealed exciting novel phenomena in these nanostructures, many scientific and technological questions remain open. A fundamental objective guiding the study of nanoscale materials is to understanding what are the new rules governing nanoscale properties and at what extent well-known physical macroscopic laws still apply in the nano-world. The vision of this DoE research program is to understand the mechanical properties of nanoscale materials by exploring new experimental methods and theoretical models at the boundaries between continuum mechanics and atomistic models, with the overarching goal of defining the basic laws of mechanics at the nanoscale. The group of the PI has developed in the last years several studies on the mechanical properties of Carbon nanotubes and oxide nanobelts, more recently the PI and her collaborators have focused their attention on the properties of two-dimensional (2D) materials, such as graphene and MoS2, which are a few-atomic- layer thick films with strong in-plane bonds and weak interactions between the layers. -

Electron back scatter diffraction (EBSD) proves that they are single crystals having identical crys- tallographic orientation. Mechanical investigations such as bending tests, lateral force measurements, and mechanical resonance measurements were performed on 100–300 nm diameter wires. The wires could be either directly employed using micro tweezers, as a singly clamped nanowire or in a doubly clamped nanobridge. The mechanical tests exhibit a surprisingly high flexibility for such a brittle material resulting from the small dimensions. Force displacement measurements on singly clamped W nanowires by an AFM measurement allowed the determination of a Young’s modulus of 332 GPa very close to the bulk value of 355 GPa. Doubly clamped W nanowires were employed as resonant oscillating nanowires in a magnetomotively driven resonator running at 117 kHz. -

Nanomechanics and Nanoelectronics: Molecule-Size Machines
Report Number 11 February, 2004 Nanomechanics and Nanoelectronics: Molecule-Size Machines Executive Summary Nanotechnology research is aimed at building minuscule machines and electronics and constructing materials molecule- by-molecule. The technology promises to open the way to faster and lower-power electronics, jewelry-size computers, data storage densities in the realm of several terabits per square centimeter, ultrahigh-bandwidth communications devices, microscopic transmitters and receivers, new types of devices like handheld biological sensors, and inexpensive manufacturing processes. Near-term nanotech developments will make materials tougher and lubricants slipperier. Longer-term research is largely focused on developing the basic building blocks of nanoscale technology — components that are hundreds of times smaller than a red blood cell. Nanoelectronics researchers are working to develop tiny transistors, memory devices, switches, wires, light emitters and networks. What to Look For Nanomechanics researchers are working to develop ratchets, actuators, motors, shuttles, springs, pistons and bearings. Nanotube electronics: There are two approaches to building both types of devices: the top- Carbon nanotubes sensors down method of today’s microelectronics manufacturing and the Hybrid nanotube-silicon chips bottom-up techniques of biology, chemistry and materials engineering. Carbon nanotube logic circuits Raw materials include inorganic matter like metals and Mass production of nanoelectronics semiconductors, molecules like polymers and carbon nanotubes, and biological molecules like DNA and proteins. Nanowire electronics: Carbon nanotubes and nanowires are especially promising because Nanowire memory chips they can be exceedingly small, assembled chemically, and have the Nanowire LEDs and lasers potential to be grown in place and en mass. Carbon nanotubes are Nanowire processor chips also very strong mechanically. -

At the nano-scale, typically defined as 1 to 100 nanometers, some phenomena are of crucial importance, while the same phenomena can be completely neglected on a larger scale. For example, the feet of a gekko are covered by nanocontacts that yield such high adhesion forces that the animal can run up on walls and even on the ceiling. At small enough distances, matter and energy become discrete, and the description of the phenomena occurring at this scale requires quantum mechanics. However, at room temperature the transitions between quantized energy levels may be concealed by the thermal vibrations of the system. As two surfaces approach each other and come into contact, electrostatic forces and van der Waals forces may cause redistribution of matter at the nano level. One effect that may occur upon contact between two surfaces is the triboelectric effect, in which charge is transferred from one surface to the other. This effect can be used to generate electricity in triboelectric nanogenerators (TENGs), where two surfaces are repeatedly brought in and out of contact, and where the charge transfer is turned into electrical energy. -
