91. Physicochemical characterization and in vitro hemolysis evaluation of silver nanoparticles
Topic: Bioscience & Health
Published: 6/7/2011
Authors: Vytautas Reipa, Jonghoon Choi, Nam Sun Wang, Victoria M. Hitchins, Peter L. Goering, Robert Malinauskas
Abstract: In anticipation of the increased use of various forms of silver as an antimicrobial agent in medical devices, the objective of this study was to evaluate the in vitro hemolytic potential of silver nanoparticles in dilute human blood, and to relate pa ...

92. CAVITY OPTOMECHANICAL SENSORS
Topic: Bioscience & Health
Published: 6/5/2011
Authors: Houxun H. Miao, Kartik A Srinivasan, Matthew T. Rakher, Marcelo Ishihara Davanco, Vladimir A Aksyuk
Abstract: We report a novel type of fully integrated optomechanical sensor and demonstrate high sensitivity mechanical displacement measurements on chip. We sense the motion of micro and nano-mechanical devices by near field coupling them to high quality facto ...

93. Fluid interactions with metafilm/metasurfaces for tuning, sensing, and microwave assisted chemical processes
Topic: Bioscience & Health
Published: 5/25/2011
Authors: Joshua A Gordon, Christopher L Holloway, James C Booth, James R. Baker-Jarvis, David R Novotny, Sung Kim, Yu Y. Wang
Abstract: In this paper we demonstrate tunability of a metafilm, which is the two-dimensional equivalent of a metamaterial, also referred to as a metasurface, by changing the permittivity in a micro-fluidic channel that interacts with the metafilm. Numerical s ...

94. Tumor volume measurement errors RECIST studied with realistic tumor models
Series: Journal of Research (NIST JRES)
Topic: Bioscience & Health
Published: 5/16/2011
Authors: Benjamin R. Galloway, Adele P Peskin, Zachary H Levine
Abstract: RECIST (Response Evaluation Criteria in Solid Tumors) is a linear measure intended to predict tumor volume in medical computed tomography (CT). In this work, using purely geometrical considerations, we estimate how well RECIST can predict the volume ...

95. Investigation of SiO2/HfO2 stacks for flash memory applications
Topic: Bioscience & Health
Published: 4/28/2011
Authors: Nhan V Nguyen, Bashwar Chakrabarti

96. Combinatorial Screening of Osteoblast Response to 3D Nano-Composite Tissue Scaffolds Using Gradients and Arrays
Topic: Bioscience & Health
Published: 4/24/2011
Authors: Carl George Simon Jr., Kaushik Chatterjee, Limin Sun, Laurence Chung Lung Chow, Marian F Young
Abstract: Current methods for combinatorial and high-throughput (CHT) screening of cell-material interactions utilize a two-dimensional (2D) format where cells are presented on flat materials surfaces [1]. However, cell response in 3D scaffolds is more represe ...

97. Effect of 3D Scaffold Structure on Osteogenic Differentiation of Human Bone Marrow Stromal Cells
Topic: Bioscience & Health
Published: 4/24/2011
Authors: Carl George Simon Jr., Girish Kumar, Marian F Young
Abstract: Structural properties of polymeric scaffolds for tissue engineering play a key role in directing osteogenesis. These properties depend on the chemical nature and the fabrication process of biomaterial. There are many protocols for fabricating scaff ...

98. NIST Reference Material Scaffolds Characterized for Cell Response
Topic: Bioscience & Health
Published: 4/24/2011
Authors: Carl George Simon Jr., Jeff M Coles
Abstract: Reference scaffolds characterized for cell response are being developed for use as a standard for biological characterization of new scaffolds. The need for reference scaffolds to serve as a calibration standard between labs has been identified as c ...

99. Nanofiber Scaffolds Induce Morphological Changes in hBMSCs Critical for Osteogenic Differentiation
Topic: Bioscience & Health
Published: 4/24/2011
Authors: Carl George Simon Jr., Girish Kumar, Christopher K. Tison
Abstract: Utilizing tissue scaffold architecture to induce stem cell differentiation is of tremendous importance to the regenerative medicine community. To this end, we have investigated the effect of nanofiber scaffold structure on primary human bone marrow s ...

100. Osteoblast Response to Protein Adsorption to 3D Polymer Scaffolds Through Pre-Ageing in Cell Medium
Topic: Bioscience & Health
Published: 4/24/2011
Authors: Carl George Simon Jr., Kaushik Chatterjee, Stevephen Hung
Abstract: Protein adsorption mediates biological responses to materials. When a biodegradable polymer scaffold is placed in aqueous, physiological medium, proteins adsorb onto the scaffold surface. The total amount, composition and structure of the adsorbed pr ...
