This sensor enables for continuous and ultra-low power wearable application.

13.2 Highly Integrated CMOS Microsystems to Interface with Neurons at Subcellular Resolution (Invited), A. Hierlemann, ETH Zurich
We demonstrate that CMOS high-density microtransducer arrays featuring several thousands of transducers (e.g. >3,000 electrodes per mm2)can be used to record from or stimulate potentially any individual neuron or subcellular compartment on the CMOS chip. High- and subcellular-resolution recordings of individual neurons and networks are presented.

A novel optofluidic device for high throughput cell sorting is demonstrated. The device combines CMOS based imaging of cells in fluidic channels with sorting based on thermal bubble generation through microheaters. The throughput is 1000 cells/s per channel with potential to sort millions of cells based on dense multichannel integration.

10:20 a.m.
13.4 Lensfree Microscopy: A New Framework For the Imaging of Viruses, Bacteria, Cells and Tissue (Invited), C. Allier, S. Vinjimore*, Y. Hennequin*, O. Cioni*, F. Momey*, T. Bordy, L. Hervé, J.-G. Coutard, S. Morel, A. Berdeu, F. Favarro, and J.-M. Dinten, CEA LETI, MINATEC
Lensfree imaging is an emerging microscopy technique based on in-line holography as invented by Gabor in 1948. Albeit the existence of the method since decades, the recent development of digital sensors, helped the realization of its full potential. Over the recent years, the performance have tremendously increased while keeping the design simple, robust, and at a reasonable low cost. The detection ability improved from 10 µm (cell) in 2009, to 1 µm (bacteria) in 2010 , down to 100 nm beads in 2012, paving the way to the detection of viruses in 2013.

10:45 a.m.
13.5 Precision Mass Measurements in Solution Reveal Properties of Single Cells and Bioparticles (Invited), S. Olcum, N. Cermak, and S. Manalis, Massachusetts Institute of Technology
Micro- and nanomechanical resonators enable mass measurements of single analytes with extraordinary precision. However the performance of these devices degrades when operated in solution due to viscous loss. The suspended microchannel resonators (SMR) were developed to overcome this limitation. The SMR is a mechanical resonator comprised of a microfluidic channel running through a cantilever oscillating at its resonant frequency. As particles flow through the integrated channel, the resonant frequency of the cantilever is transiently modulated by the particle’s buoyant mass, enabling precise mass measurements in solution. Here, we will discuss the recent advancements of the SMR technology that enabled the quantification of single cell growth and density, and resolving nanoparticles down to 10 nm with single attogram precision. Finally, we will present a technology for simultaneously monitoring multiple resonances that enabled high throughput growth rate measurements. We will show how the same technology can potentially determine the shape of nanoparticles along with their masses.

11:10 a.m.
13.6 Fabrication and Analysis of SiN Nanopores for Direct DNA Sequencing (Invited), I. Yanagi, Y. Goto, R. Akahori, K. Matsui, Y. Nara, T. Yokoi, and K.-i. Takeda, Hitachi, Ltd.
This paper summarizes the latest developments of solid-state nanopores in our laboratory. For the realization of direct DNA sequencing with solid-state nanopores, a simple method to precisely fabricate nanopores with diameters of 1 to 3 nm has been developed. From the measurements of translocation events of DNA through the fabricated nanopores, it was confirmed that single-stranded DNA (ssDNA) could pass through the nanopore even when the diameter of nanopore is down to 1.2 nm. In addition, it was discovered that the translocation speed of single-stranded DNA is faster than that of double-stranded DNA (dsDNA) by two or three orders of magnitude.

A methodology for optimizing the energy-delay performance of a nano-electro-mechanical relay is developed. Contrary to popular belief that structural stiffness should be minimized to achieve minimum switching energy, this work shows that the effective spring constant should be relatively large. The optimal energy-delay of an aggressively scaled NEM relay (with 5 nm contact gap as-fabricated) is presented.

In this work, we demonstrate for the first time the performance of polysilicon NEMS fabricated with a low temperature process compatible with a NEMS above IC 3D integration.

We found the best process window (laser annealing conditions and dopant concentration) to optimize poly-Si NEMS with excellent features compared to conventional c-Si NEMS. The goal of this study is to replace c-Si for low cost 3D integration.

29.1 Field-Effect Control of Ions Beyond Debye-Screening Limit in Nanofluidic Transistors, Q. Ran, Y. Liu*, and R.W. Dutton, Stanford University, *Zhejiang University
We investigate the field-effect control of ions in nanofluidic transistors (NFTs) with characteristic channel size (~100nm) significantly larger than the system’s Debye length (~10nm). These 100nm NFTs achieve an ionic current modulation ratio of ~2.5, demonstrating better performance than the state-of-the- art 20nm NFTs. The result attests a new operating regime beyond the Debye-screening limit. The relaxed constraint on channel size offers advantages in device manufacturing, testing, and reliability. It also opens up new applications in biological sensing and sample preparation.

2:50 p.m.
33.4 Artificially Intelligent Nanoarrays for Disease Detection via Volatolomics (Invited), H. Haick, Technion – Israel Institute of Technology
According to recent reports, more than 15 million deaths occur annually due to infectious diseases1 and approximately 57 million deaths occurred in 2008 from non-communicable diseases including cancer2. The spectrum of currently available medical methods does not enhance detection of many diseases, primarily due to technology limitations and their complexities, causing a delay in diagnosis.1-3 For this reason, there is an urgent need for inexpensive and minimally invasive technology that would allow efficient early detection, stratifying the population for a personalized therapy, and for rapid bed-side assessment of treatment efficacy. An emerging approach that has a high potential to fulfill these needs is based on the so-called “volatolomics”, viz. chemical processes involving profiles of highly volatile organic compounds (VOCs) which are by-products of metabolic and pathological processes and are emitted from various body fluids including breath, skin, urine, blood, and others. 3- 6
