TitleNanotechnology in the development of future nanoelectronics and sensors
Exploration of nanomaterials for future nanoelectronics, optoelectronics, sensors, and other applications has been an active area of research and has overwhelmingly focused on carbon nanotubes and graphene. A variety of one-dimensional inorganic nanowires have also been explored for a competitive avenue for many of these applications while being amenable to grow by chemical vapor deposition (CVD). Most of these nanowire materials have been used previously in the same applications as two dimensional thin films, but now in the one-dimensional form they provide quantum confinement, opportunities for bandgap engineering and exceptional surface quality. We have used nanowires to construct phase change memory, RRAM, piezoelectric energy harvesting and biosensors. We have also used oxide nanowires recently towards wearable electronics applications and some examples of e-textile will be presented. Recently paper has emerged as a viable substrate for electronics, sensors, batteries and other components and examples from our work will be given. Finally, we have fabricated nanoscale vacuum tubes using entirely silicon technology and obtained high frequency performance that exceeds state-of-the-art silicon devices. Vacuum is superior for electron transport compared to all semiconductors. These vacuum transistors have the potential for THz electronics. The device physics, fabrication and results will be presented.

TitlePiezotronics for functional system and nanogenerators as new energy technology
For Wurtzite and zinc blend structures that have non-central symmetry, such as ZnO, GaN and InN, a piezoelectric potential (piezopotential) is created in the crystal by applying a strain. Such piezopotential can serve as a “gate” voltage that can effectively tune/control the charge transport across an interface/junction; electronics fabricated based on such a mechanism is coined as piezotronics, with applications in force/pressure triggered/controlled electronic devices, sensors, logic units and memory. By using the piezotronic effect, we show that the optoelectronc devices fabricated using wurtzite materials can have superior performance as solar cell, photon detector and light emitting diode. Piezotronics is likely to serve as a “mechanosensation” for directly interfacing biomechanical action with silicon based technology and active flexible electronics. This lecture will focus on the updated progress in the field and its expansion to 2D materials.

Developing wireless nanodevices and nanosystems is of critical importance for sensing, medical science, environmental/infrastructure monitoring, defense technology and even personal electronics. It is highly desirable for wireless devices to be self-powered without using battery. Nanogenerators (NGs) have been developed based on piezoelectric, trioboelectric and pyroelectric effects, aiming at building self-sufficient power sources for mico/nano-systems. The output of the nanogenerators now is high enough to drive a wireless sensor system and charge a battery for a cell phone, and they are becoming a vital technology for sustainable, independent and maintenance free operation of micro/nano-systems and mobile/portable electronics. An energy conversion efficiency of 50% and an output power density of 1200 W/m2 have been demonstrated. This technology is now not only capable of driving portable electronics, but also has the potential for harvesting wind and ocean wave energy for large-scale power application. This talk will focus on the updated progress in NGs.

TitleTemplated Self-Assembly of Arrays of Nanostructures
Arrays of nanowires, nanodots and more complex nano-scale structures have a wide range of applications in microsystems. Arrays of nanoscale structures can be formed using self-assembly that is templated by larger-scale lithographically defined structures. Three examples will be discussed; templated pore formation in porous alumina, topographic templating of solid state dewetting, and patterned templating of solid state dewetting.

TitleNano-Bio Hybrid Materials for Nanomedicine
The purpose of this presentation is not to provide the definition of convergence in terms of various science and technology disciplines, but to help audience to understand what the hybrid materials are, and how to design and synthesize novel nano-bio hybrid materials, to induce their synergetic effects, and eventually to apply them for nanomedicine.
A novel concept of nano-bio hybrids with imaging, targeting and drug delivery functions will be proposed to get breakthroughs in gene and drug delivery researches. In order to examine 2d-material as nanovehicle for gene and drug delivery, an attempt has been made to prepare host-guest interaction mediated nanohybrid assemblies by the coprecipitation and/or ion-exchange type reactions, where guest biomolecules [antisense and siRNA] or anticancer drugs [Methotrexate and Pemetrexed (Alimta)] could be immobilized in the interlayer space of host layered double hydroxides (LDHs). And thus encased guest drug molecules could also be slowly released out in a body fluid depending upon the chemical design of host 2-d LDHs.
According to the intercellular uptake experiments for LDH nanoparticles, we found for the first time that drugs or genes in LDHs were effectively permeated inside the cell by clathrin-mediated endocytosis. Since LDH nanoparticles are partially soluble in cytosol, the drug concentration in the cell increases and as a consequence, the drug efficacy is maximized. More recently, the intracellular trafficking pathways of LDH nanoparticles, depending on particle sizes, were clearly demonstrated on the basis of quantitative immunofluorescence microscopy and confocal laser scanning microscopy analyses.
It is, therefore, concluded that the present multifunctional nano-bio hybrid drug delivery system could provide a promising integrative therapeutic action in chemo-and gene therapy.

TitleBio-Molecular and Cellular Assemblies at Interfaces
Graphene is a fascinating new material [1], and its peculiar properties hold promises for a great technological impact [2, 3]. Nevertheless, to allow for a real exploiting of their extraordinary properties, a complete control of the fabrication steps of graphene-based devices is mandatory. In this contribution we will show an integrated approach for the integration of graphene membranes in state-of-the-art technological processes and for the exploitation of their properties in an applicative framework.
Our approach starts from the careful control of the synthesis parameters of the CVD growth of graphene membranes, as well as of their structural and functional properties. It moves then to the definition of tailored transfer processes leading to the integration of graphene membranes in a wide class of functional substrates (technological surfaces, glass, plastic and polymeric flexible substrates), to provide the control of physical and chemical properties over large area, typically mandatory in the devices fabrication processes. Final step is the definition of the complete set of technological processing steps needed to achieve a full integrability of the membranes within the processes of fabrication of micromachined devices.
Examples concerning design and fabrication of micromachined thermal and thermoelectric sensing devices, as bolometers and thermopiles, or concerning the integration of graphene membranes as transparent conductive electrodes in thin film solar cells [4], dye sensitized solar cells [5], organic light emitting transistors [6] and flexible capacitors [7] will be provided.

TitleThe interaction between nanoparticles and living organisms - the search for guiding principles
Many of the current potentially transformative scientific efforts worldwide is the effort to understand how nanoscale objects interact with living organisms. It has thus been of interest to find guiding principles for such a new scientific discipline. [1]. This arena of science constitutes a step beyond a simple progressive growth of knowledge on materials and organisms, for two major reasons. Firstly, the nanoscale is unique in biology, and our capacity to engineer on that scale is transformative. The endogenous (intrinsic) machinery of biology is defined and operates on the nanoscale. Typical biomolecules and assemblies that are actively transported around organisms by specific motors and drivers are between 5-80nm. This means that nanoparticles are also actively (using the energy of the cell) transported around cells and biological barriers all unlike small molecules which passively partition into biological compartments (cells, organs etc). Secondly, the power of being able to communicate with, and use those endogenous mechanisms of biology is potentially transformative in practical terms. It is clear, and is often discussed how transformative could be the contribution of nanoscience to medicine, diagnostics, and new kinds of cell therapies.

However, with this enormous potential power to engage (interact) with the machinery of organisms there are also challenges. First of all, the complexity of the interaction is remarkable, much more so than for small cell and molecules, or large particles. Capturing this new capacity for benefit of human society will require dedication and commitment, indeed an exceptional generational effort, rather than peripheral research. To some degree, both the potential, and the challenge, of this field may have been underestimated, and only now are we beginning to face the need to invest in guiding principles and laws governing the whole arena. We also grow more confident though also in the potential, and our capacity to master it.

We discuss progress being made in understanding how interactions between nanoscale objects and living organisms occur, and their governing principles. [2,3] We argue that the future lies in pressing forward to develop a truly microscopic (molecular scale) understanding between the nanoscale and living organisms. [4]
