• Article: Quantum Dots-Enabled High-Resolution Analysis of Gene Copy Number Variation

  Yi Zhang, Tza-Huei Wang
  [show abstract] [hide abstract]
  ABSTRACT: We have developed a novel quantum dot (QD)-enabled copy number variation (CNV) quantification assay. Current CNV detection techniques are not able to reliably quantify less than a twofold difference. The assay employed a QD to physically transform the target copy number into different electrophoretic mobility (EM) levels that could be assessed by the electrophoresis. We built a model to predict the electrophoretic migration and explain the band broadening of the QD-DNA nanocomplex. The nanoassay demonstrated a remarkable resolution, capable of distinguishing a Li fold (~9%) difference in the target copy number. We applied the nanoassay to detect the CNV of the Rsf-1 gene that plays an important role in ovarian cancer.

• Article: A Beacon of Light

  ABSTRACT: We demonstrated controlled conversion of DNA/Ag NCs between bright and dark states and designed a new molecular probe, NCB, for homogeneous detection of nucleic acid targets. Not relying on Forster energy transfer as the fluorescence on/off switching mechanism, NCBs have the potential to reach an ultrahigh S/B ratio in molecular sensing. Since the fluorescence enhancement is caused by intrinsic nucleobases, our detection technique is simple, inexpensive, and compatible with commercial DNA synthesizers. Here, we demonstrated that a palette of NCB light-up colors can be produced from the same origin by employing different proximal sequences. We also showed that the NC-nucleation sequences capable of achieving strong red fluorescence enhancement share a common 5'-C₃NNNNNC₄ motif.

  Article: In It to WIN It

  A. Carty, J.T.W. Yeow
  [show abstract] [hide abstract]
  ABSTRACT: Nanotechnology and its applications are poised for explosive growth in the years ahead. The Waterloo Institute for Nanotechnology (WIN), with a new state-of-theart Quantum Nano Centre, a young and dynamic research faculty, and home to hundreds of Canada's best nanotechnology engineering students, is positioned to contribute to that growth as one of the foremost centers for nanoresearch and innovation in the world. From developments in advanced lithium-ion battery technologies, next-generation solar photovoltaic cells, and thermoelectric conversion materials to hybrid bionanocomposite materials and nanocatalysts, advances in fundamental understanding of materials design will lead to real-world applications. WIN anticipates major progress in organic electronic devices, large-area displays, and miniaturized CNTs or graphene-based X-ray sources. Single-electron and single-photon quantum devices enabled by nanotechnology will be fabricated and employed in quantum information processing. Handheld lab-on-a-chip diagnostic devices with microfluidic flow in channels controlled by electric fields will become a reality for disease and pathogen diagnosis, replacing more bulky and expensive analytical instrumentation. Drugs encapsulated in nanoparticles delivering therapies directly to a cancerous tissue will be in clinical trials for early adoption, and new, innovative nanotools for imaging and measurement will be introduced. These are only a few of the exciting results researchers expect to see from the next ten years of research at WIN.

  Article: A Closer Look at DNA Nanotechnology

  O. Tabata
  [show abstract] [hide abstract]
  ABSTRACT: A nanosystem in which multiple nanoscale functional components made of a variety of nanomaterials are integrated with a microelectromechanical system (MEMS) becomes increasingly important as a key device for the next generation. A deoxyribonucleic acid (DNA) nanotechnology is expected to play an important role to bridge the gap between the nanoscale components (nanocomponents) and the microscale MEMS as a complementary approach for top-down manufacturing technique and bottom-up manufacturing technique to realize nanosystems. From the design viewpoint of a system, such as large-scale integrated circuits (LSI), MEMS, and nanosystem, it should be noted that the complexity is an essence to generate its functionality. The functionality of LSI/MEMS/nanosystem, where functional components are simply arranged in a periodic order, is limited. Periodic nanostructure can be a part of a nanosystem as a nanocomponent, but it is not enough. Interaction and cooperation of multiple nanocomponents with different features make it possible to generate a unique and useful functionality of a nanosystem.

  Article: Highly Sensitive and Selective Explosive Detector Based on Nanoporous Silicon Photonic Crystal Infiltrated with Emissive Organics [Nanoproducts]

  I.A. Levitsky
  [show abstract] [hide abstract]
  ABSTRACT: Emitech Inc. (www.emitechinc.com) is developing a porous silicon (PSi) microcavity (MC)-based fluorescent detector for explosives. It was initially funded by the Army Small Business Innovation Research Phase II contract (Figure 1). The sensory part of the device is composed of a nano-PSi photonic crystal with MC, infiltrated with fluorescent organics that are specific to target explosive vapors and particulates. It is important that the nanodevice structure provides an extremely large interfacial area between the sensory material and the analyte vapors leading to its highest sensitivity, which is critical for fast trace detection of low vapor pressure explosives. An important feature of the nanodevice is the real-time sampling system (integrated with sensory head) based on the proprietary thermal air-jet technology.

  ABSTRACT: Over the past few years, virus detection techniques have become increasingly important because of the frequent occurrence of new pathogenic virus strains. At present, there are two well-established diagnostic techniques for viruses: immunoassay and DNA-/RNA-based methods. Immunoassay, considered the gold standard, uses either direct immunofluorescent assay or membrane enzyme-linked immunosorbent assay to first isolate the virus and then characterize it using serological or other molecular biological tools. Typical drawbacks for immunoassay include poor specificity and low sensitivity. By comparison, DNA-/RNA-based methods such as reverse transcription-polymerase chain reaction assays are much more specific and sensitive. These methods, however, are typically very time consuming since the protocol requires a series of DNA/RNA isolation, concentration, and gel electrophoresis.

• Article: The Quiet Revolution of Inorganic Nanowires

  M. Meyyappan, Jeong-Soo Lee
  [show abstract] [hide abstract]
  ABSTRACT: Inorganic materials in the form of thin films are ubiquitous in various applications. In the last two to three decades, the research community and industry have grown thin films of silicon, germanium, III-V compounds, various oxides, nitrides, antimonides, metals, and dielectrics using techniques such as chemical vapor deposition (CVD), metal organic CVD (MOCVD), and molecular beam epitaxy (MBE). These thin films have directly contributed to all the advances we see today in computers, electronics, optoelectronics, and microelectromechanical systems. Some examples include silicon and its oxide and nitride in logic and memory chips, GaAs and AlGaAs in lasers, and tin oxide thin films in chemical sensors. In the nano era, recent efforts have focused on growing all of the aforementioned materials in the form of one-dimensional (1 -D) nanowires.

• Article: Nanotech Commercialization in the United States [Commercialization]

  L.J. Ross
  [show abstract] [hide abstract]
  ABSTRACT: In the previous issue, I focused on R&D trends and also referred to concerns regarding the United States and the importance of maintaining steady funding by the public and private sectors for emerging technologies such as nanotech. The overall R&D funding climate is always a leading indicator of future innovation activity, and delays or reductions can spread out the time necessary to bring to market commercial products. Though companies and even the government become hard pressed to keep up the pace in a down economy, the ramifications of falling behind can be severe in terms of lost opportunities and competitiveness. Many areas of nanotechnology are still in a nascent stage of development, and sudden breakthroughs may lead to strong disruptions in existing technology and product markets in relatively short order.

• Article: Low Processing Temperature of Lead-Free Solder Interconnects [Nanopackaging]

  Hongjin Jiang, C.P. Wong
  [show abstract] [hide abstract]
  ABSTRACT: Solder paste is a homogeneous and kinetically stable mixture of solder alloy powder, flux, and vehicle, which is capable of forming metallurgical bonds at a given soldering condition. The thermal properties of tin/silver/copper (SnAgCu) alloy nanoparticles of different sizes were studied by differential scanning calorimetry (DSC). The particle size-dependent melting point and latent heat of fusion were also observed. The nanoparticle pastes completely melted and wetted on the copper surface, and tin/copper intermetallic compounds (IMCs) were formed after the reflow process. These low-melting-point SnAgCu alloy nanoparticles pastes could be used for low processing temperature of lead-free solder interconnect applications.

• Article: Exploring the Limits of Dielectrophoretic Nanoassembly

  Ming Li, Wen Li
  [show abstract] [hide abstract]
  ABSTRACT: Limitations of dielectrophoretic (DEP) assembly for gold particles and optical dielectrophoretic (ODEP) manipulation of spherical particles are theoretically analyzed in this article. The results in the "Gold Nanoparticle Assembly" section reveal that the core-shell sphere polarization model is effective for characterizing the frequency-dependent mechanism of DEP manipulation, which concludes that the rate of gold pearl chains formation tended to zero at highand low-frequency limits and had a maximum at a narrow midrange frequency band. Analysis with scaling laws shows that approximately 2 nm will be the size limit for the DEP assembly of gold particles. In the "ODEP Manipulation" section, the capabilities of particle transportation in ODEP systems are analyzed. With a virtual spot electrode of 1 ¿m, it is theoretically possible to manipulate 2-nm particles using ODEP systems.

• Article: Delivering on the Promise in Real-World Applications

  J. Dorr
  [show abstract] [hide abstract]
  ABSTRACT: Few technologies on the near-term horizon offer the potential for game-changing results as do CNT products. In an age where the state of the art in global defense, transportation, and energy depends on meaningful advancement and delivery of novel materials, it is critical to view scalability to be as important as product performance itself. To date, few nanotechnology manufacturers have solved the scaling problem, choosing instead to focus most of their resources on research and advances in material science. In the end, materials without a meaningful path to volume delivery will remain as novel inventions with very little practical value. Those nanotechnology manufacturers that address the issue of scaled production will indeed change the game in ways we can only begin to appreciate today.
