TITLE: In-Situ Soft Nano Particles for Targeted Drug Delivery

SPEAKERS: Dr. Jayakumar Rajadas, Director of Biomaterials and Advanced Drug Delivery Laboratory, Stanford University School of Medicine

ABSTRACT:
Pre-Designed nanosomes, self-assembled liposome shells used to protect and help active molecules penetrate cells, interact with biofluids such as blood and intestine secretions to develop into structures of desired patterns. We have shown these soft particles can recognize endothelial linings of the blood capillaries that are proximal to the affected tissues in the heart, brain and liver. We have used these structures to stabilize and target the fragile peptides, proteins and water insoluble therapeutic molecules to different organs. We use various biophysical approaches such as AFM, fluorescence, and NMR to understand the structural details of these molecules

TITLE: Nanoscale Optofluidic Devices

SPEAKERS: Prof. Holger Schmidt, Department of Electrical Engineering, UC Santa Cruz

ABSTRACT:
Integrated photonic devices have traditionally been designed for data communications using exclusively solid-state materials. However, a vast area of potential applications, in particular in the life sciences, involve interactions of light with liquids and gases. Recently, a number of optofluidic approaches have been considered that are aimed at integrating such non-solid media with chip-scale photonic structures. We have developed a versatile, planar photonic platform based on hollow-core optical waveguides. I will describe the physical foundations and optical characteristics of this platform and a broad range of devices and capabilities that are made possible by this approach. In particular, I will discuss the incorporation of nanoscale features for enhanced chip-scale particle detection, manipulation and trapping. I will outline a path to a fluidically and optically integrated “optofluidic” platform that enables direct detection of single nucleic acids and proteins for a new generation of photonics-based molecular diagnostic instruments.

SPEAKER BIOGRAPHY:
Holger Schmidt received his PhD degree in electrical and computer engineering from the University of California, Santa Barbara.

TITLE: Sub-5 nm Patterning Using Helium Ion Beam and Nanoimprint Lithography

SPEAKERS: Prof. Wei Wu, Department of EE, University of Southern California

ABSTRACT:
Helium ion beam lithography (HIBL) is a recently developed nanolithography technology. It uses a He ion beam to direct write patterns in the same fashion as electron beam lithography (EBL). Due to its advantages, such as smaller focusing spot and less proximity effects than electron beam, it can go beyond the resolution of EBL. We have demonstrated patterning of various nano-patterns using HIBL. For example, we achieved dense lines with half-pitch down to 4 nm. Moreover, we also achieved sub-5 nm patterning using nanoimprint lithography (NIL) with molds fabricated by HIBL. The combination of NIL and HIBL mitigates the two major drawbacks of HIBL: low throughput and the tendency to damage substrates. We also used HIBL as a direct milling tool to pattern metal and Graphene with dense lines down to 4 nm half-pitch. Our Raman spectra show that the HIBL patterned Graphene nanoribbons (GNRs) have lower line-edge roughness than reported GNRs patterned by EBL.

TITLE: Low-cost scalable production and applications of single-walled carbon nanotubes

SPEAKERS: Prof Mikhail Predtechensky, CTO, & Mr Yuri Koropachinsky, President, OCSiAl Group

ABSTRACT:
The closure by Bayer and Showa Denko of their large-scale facilities for the production of multi-walled CNT (MWCNT) is a benchmark event in the CNT industry. The reason for the scaling down of the production of MWCNT is that, regardless of the low price of MWCNT, their agglomerated form significantly hampers their introduction into the matrix, and what is especially important, in order to achieve similar properties of materials one needs to introduce into the material incomparably higher concentrations of MWCNT, than if one were to use SWCNT. There are two barriers for the broad application of SWCNT – their high price (tens of thousands of $ per kg) and the absence of scalable technologies for their synthesis. In order for industrial applications to become possible their price needs to be reduced to single digit $ per kg, and there have to be reactors producing at least tons of SWCNT per annum. This presentation announces the creation by OCSiAl of a new technology for the production of single wall carbon nanotubes and demonstrates the possibilities for improving the properties of different materials through the addition of such nanotubes. The presentation demonstrates some results of the above-mentioned applications of SWCNT including conductive composites which can be painted electrostatically, flexible transparent conductive film with high transparency and low resistance. lithium-ion batteries with increased power and cycle life, and many others Thus, the mass availability of low cost SWCNT has the potential to cause very significant impact on a variety of industries.

TITLE: Nanophosphors in Cancer Diagnosis, Therapeutics and Drug Delivery

SPEAKER: Dr. P. R. Ravilisetty, President Specialty Phosphors Inc.

ABSTRACT:
Mammography is considered to be the best tool for the detection of breast cancer, and high-resolution images can detect cancer more accurately than other systems, particularly with computer-aided diagnosis (CAD) systems. Current digital mammography systems use needle shape CsI:Tl phosphor pixels <100 μm in size. The stability and life span of these phosphor needles are limited due to their hygroscopic and fragile nature. Our approach to avoid current limitations in digital mammography is to grow micron-size pillars of very stable scintillator materials using novel nanophosphors.

Photodynamic therapy (PDT) is currently used clinically where a photosensitizer such as Photofrin is activated with laser light to produce oxygen radicals that kill cancer cells. Visible light only penetrates few millimeters into tissue. IR light penetrates much deeper, but does not activate photo sensitizers. Upconverting phosphors (UCPs) absorb infrared photons and emit visible photons. Due to low conversion efficiency, UCPs do not deliver enough visible light. X-ray excitable nanophosphors are good candidates to deliver higher flux visible light to sensitize PDT drug. Currently, we are investigating the possibility of adopting inorganic nanophosphors as a biological contrast agent for medical imaging in X-ray/optical combo. We are also working on X-ray luminescence computed tomography (XLCT), a new molecular imaging modality with medical research groups at Stanford University. This combined modality may yield an increase in the utility of omnipresent X-ray imaging by enabling concurrent molecular imaging. Nanophosphors with magnetic properties are being explored at SPI in drug delivery.

Nanophosphors synthesis, characterization, and possibilities of using in early detection of breast cancer, X-ray PDT, medical imaging in a combined X-ray/optical instrument and drug delivery will be presented.

SPEAKER BIOGRAPHY:
Dr. Ravilisetty is a President of Specialty Phosphors Inc., a startup company dedicated to development and manufacturing of nanophosphors for medical, display, lighting and security applications. Dr. Ravilisetty spent five years in CECRI (Government Lab.), India developing optically stimulated dosimetry and color TV phosphors.

TITLE: Nano-Justified: Why Nano Matters for Silicon Thermoelectrics

SPEAKER: Akram Boukai, CEO and Co-Founder, Silicium Energy

ABSTRACT:
Nano has been an overhyped buzz word for more than a decade and yet it’s difficult to point to a product that benefits from the nanoscale. The field of thermoelectrics, however, benefits tremendously from nanostructuring due to dissimilar length scales between heat and electron transport. Silicon in particular has very different length scales for heat and electron transport. Recently, silicon based thermoelectric devices that utilize a finely tuned nanostructure have delivered high performance in the lab. This discovery culminated in the formation of Silicium Energy in 2011 with funding from Khosla Ventures. Silicium Energy is developing next-generation thermoelectric devices with unprecedented performance designed to revolutionize markets for waste heat recovery and refrigeration. Silicium’s platform has the potential to achieve high ZT across a wide range of temperatures at low cost. Silicium leverages technology created at Caltech and the University of Michigan, which utilizes a “fab-less” approach for high performance thermoelectrics using off the shelf silicon wafers.

SPEAKER BIOGRAPHY:
Akram Boukai obtained his PhD from the California Institute of Technology in 2008. His research focused on the thermoelectric properties of nanostructured silicon where he produced and measured high efficiency thermoelectrics. He then went on to become an Assistant Professor at the University of Michigan in the Materials Science and Engineering Department. There his group made a breakthrough in the manufacture of nanostructured silicon thermoelectrics, which resulted in the formation of a Khosla Ventures funded startup, Silicium Energy. Akram now serves full-time as the co-founder and CEO of Silicium Energy and is continuing his dream of taking his laboratory discovery on silicon thermoelectrics to market.

TITLE: Searching for Profits at the Intersection of Nanotech and Electronics

SPEAKER: Ross Kozarsky, Senior Analyst, Lux Research Inc.

ABSTRACT:
Despite massive media attention and investments, nanotechnology has yet to live up to the hype, and many are still confused as to the best context for examining “nano” for the purpose of business-minded analyses. Rather than regarding nano as its own industry, it is best considered an enabling technology that fits into and enhances the value chains of already existing industries. The nanotechnology value chain – namely, the distinction between nanomaterials, nanointermediates, and nano-enabled products – is a very useful tool for conducting such an analysis. After a discussion of this value chain, this presentation will review some of Lux’s key tools for assessing both a company’s technical value and business execution. It will then explore key electronics application spaces of nanotechnology – including transparent conductive films, conductive composites, imaging, and in vitro diagnostics – which will serve as case studies for solidifying common themes of what it takes to be successful as a nanotech developer.

SPEAKER BIOGRAPHY:
Ross Kozarsky is a Senior Analyst who leads Lux Research’s Advanced Materials team. Ross’ primary responsibilities include providing strategic advice and on-going intelligence for emerging coating, composite, metal, and platform materials that serve as enabling technologies for new markets and applications in industries ranging from oil and gas to electronics.

TITLE: Conductive-bridge memory (CBRAM) with excellent high-temperature retention and tolerance to high levels of Gamma Radiation

SPEAKER: Dr. Venkatesh P. Gopinath, V.P. of CBRAM Technology at Adesto Technologies

ABSTRACT:
Development activities in resistive memories have undergone explosive growth in the past several years. Conductive-Bridge RAM (CBRAM) is a family of resistive memory that offers significant advantages of performance, cost, scaling and power as compared to today’s non-volatile memory technologies. While several implementations of RRAM technology have demonstrated excellent potential as next generation memory technology, the barriers to achieve commercial success remain rooted in overcoming process integration challenges as well as market and application requirements. Further, reliability and functional requirements for memory products vary depending on the end application for which they will be utilized.
This talk will focus on a family of fully CMOS integrated CBRAM technology that not only shows excellent performance and power advantages over today’s technologies but also demonstrates excellent high temperature (>200ºC) retention and tolerance to very high levels (5Mrad) of Gamma radiation. These features allow CBRAM to replace conventional NVM technology for traditional applications as well as solutions for operations under harsh operating conditions like automotive, medical (sterilization) and space applications.

SPEAKER BIOGRAPHY:
Dr. Venkatesh (“P.G.”) Gopinath is the V.P. of CBRAM Technology at Adesto Technologies. His responsibilities include R&D and transferof CBRAM technologyto volume manufacturing.
