1. Airbrushed Nanofiber Scaffolds Support Bone Marrow Stromal Cell Differentiation
Topic: Medical Devices
Published: 11/1/2013
Authors: Carl George Simon Jr., Wojtek J Tutak, Sumona Sarkar, Tanya M. Farooque, Jyotsnendu J. Giri, Dongbo Wang, Sheng Lin-Gibson, Joachim Kohn, Durgadas Bolikal
Abstract: Nanofiber scaffolds are effective for tissue engineering since they emulate the fibrous nanostructure of native extracellular matrix (ECM). Although electrospinning has been the most common approach for fabricating nanofiber scaffolds, airbrushi ...

2. An Average Enumeration Method of Hyperspectral Imaging Data for Quantitative Evaluation of Medical Device Surface Contamination
Topic: Medical Devices
Published: 9/15/2014
Authors: Hanh Le, Moon Kim, Jeeseong Hwang, Yi Yang, Pawneena U-Thainual, Jin Kang, Do-Hyun Kim
Abstract: We propose a quantification method called Mapped Average Principal component analysis Score (MAPS) to enumerate the contamination coverage on common medical device surfaces. The method was adapted from conventional Principal Component Analysis (P ...

3. Challenges of the Changing Robot Markets
Topic: Medical Devices
Published: 7/19/2013
Authors: Gurvinder Singh Virk, Carol Herman, Roger V Bostelman, Tamas Haidegger
Abstract: Service robots are becoming an integrated part of daily life, entering even the most complex scenarios, yet at a slower pace than previously anticipated. This paper presents an overview of the changing area of robotics and the new challenges being fa ...

4. Dielectrophoretic Trapping of P19 Cells on Indium Tin Oxide based Microelectrode Arrays
Topic: Medical Devices
Published: 11/8/2013
Authors: Aveek Gangopadhyay, Saugandhika Minnikanti, Darwin R Reyes-Hernandez, Mulpuri V. Rao, Nathalia Peixoto
Abstract: A microfabricated device comprised of a microelectrode array (MEA) and a microfluidic channel is presented here for the purpose of trapping cells using positive dielectrophoresis (DEP). Transparent indium tin oxide (ITO) electrodes are patterned in a ...

5. Fabrication of Microelectrodes on Polyester Membranes for Dielectrophoretic Cell Capture
Topic: Medical Devices
Published: 6/18/2012
Authors: Conni Hanke, Petra S. Dittrich, Darwin R Reyes-Hernandez
Abstract: We present a new system for cell capturing on permeable polyester (PET) membranes using dielectrophoretic forces. For the first time gold microelectrodes were fabricated on PET membranes using conventional photolithographic techniques. Their charac ...

Topic: Medical Devices
Published: 10/28/2012
Authors: Conni Hanke, Petra S. Dittrich, Darwin R Reyes-Hernandez
Abstract: A cell co-culture was generated on opposite sides of a permeable polyester membrane (PET) membrane by combining dielectrophoretic (DEP) and electrostatic forces to hold cells against gravity in a multilayer microfluidic device (Figure 1). HepG2 cell ...

7. Genomic Reference Materials for Clinical Application
Topic: Medical Devices
Published: 11/21/2014
Authors: Justin M Zook, Marc L Salit
Abstract: Reference Materials are well-characterized, homogeneous, and stable samples that can be used to understand measurement performance. The Genome in a Bottle Consortium is developing whole human genome DNA Reference Materials from large batches of DNA ...

8. Hybrid Cell Adhesive Material for Instant Dielectrophoretic Cell Trapping and Long Term Cell Function Assessment
Topic: Medical Devices
Published: 8/16/2011
Authors: Darwin R Reyes-Hernandez, Jennifer S. Hong, John T Elliott, Michael Gaitan
Abstract: We present the development and evaluation of an engineered hybrid cell adhesive surface for instant dielectrophoretic trapping and patterning of cells in a microfluidic device. This work demonstrates that a hybrid cell adhesive material (hCAM) prepar ...

9. International Standards Efforts Towards Safe Accessibility Technology for Persons With Disabilities: Cross-industry Activities
Topic: Medical Devices
Published: 12/31/2010
Author: Roger V Bostelman
Abstract: This paper describes the US and International Standards activities ongoing within the National Institute of Standards and Technology, Intelligent Systems Division (ISD) with regards to accessibility for the disabled. There is a critical role of stan ...

10. Machine Learning Analysis for Identification of Cell Shape Metrics Associated with Stem Cell Differentiation in Nanofiber Scaffolds
Topic: Medical Devices
Published: 4/19/2014
Authors: Desu Chen, Sumona Sarkar, Stephen J Florczyk, Subhadip Bodhak, Carl George Simon Jr., Joy P Dunkers, Julian Candia, Wolfgang Losert
Abstract: Cell shape has been demonstrated to be closely related to cell function and may be an important predictor of cell fate. Many metrics are available to describe cell shape, however the relationship of these metrics to cell fate are not well understood ...
