21. Separation and Metrology of Nanoparticles by Nanofluidic Size Exclusion
Published: 8/11/2010
Authors: Samuel M Stavis, Jon C Geist, Michael Gaitan
Abstract: A nanofluidic approach to the separation and metrology of nanoparticles is demonstrated. Advantages of this approach include nanometer-scale resolution, nanometer-scale to submicrometer-scale range, mitigation of hydrodynamic and diffusional limitat ...

26. Polyelectrolyte Multilayer-Treated Electrodes for Real-Time Electronic Sensing Cell Proliferation
Series: Journal of Research (NIST JRES)
Published: 4/1/2010
Authors: Geraldine I. Mijares, Darwin R Reyes-Hernandez, Jon C Geist, Michael Gaitan
Abstract: The feasibility of using and the performance of non-biological polyelectrolyte multilayer (PEM) films to facilitate cell attachment on titanium-tungsten alloy/gold (TiW/Au) electrodes for the detection of cellular responses in cell assays are investi ...

27. Temperature-Programmed Gas-Sensing With Microhotplates: An Opportunity to Enhance Microelectronic Gas Sensor Metrology
Published: 10/5/2009
Authors: Jon C Geist, Muhammad Yaqub Afridi
Abstract: It is only recently that the ITRS (International Technical Roadmap for Semiconductors) has identified functional diversification through heterogeneous integration as a key enabler of future industry growth. This paper describes a powerful temperatur ...

28. Generalized temperature measurement equations for rhodamine B dye solution and its application to microfluidics
Published: 9/2/2009
Authors: Jayna J Shah, Michael Gaitan, Jon C Geist
Abstract: Contact-less mapping of temperature distributions based on ratios of fluorescent signals is a ubiquitous temperature detection technique. However, application of calibration equations that relate fluorescence intensity ratios to temperature pose sev ...

29. Analog BIST Functionality for Microhotplate Temperature Sensors
Published: 9/1/2009
Authors: Muhammad Yaqub Afridi, Christopher B Montgomery, Elliott cooper-Balis, Stephen Semancik, Kenneth Gruber Kreider, Jon C Geist
Abstract: In this paper we describe a novel microhotplate temperature sensor calibration technique suitable for Built-In Self Test. The technique only requires short-term temperature stability from the four-wire polysilicon heater/temperature sensors that are ...

30. Mapping the Edge-Roughness of Test Structure Features for Nanometer-Level CD Reference-Materials
Published: 4/2/2009
Authors: Michael W Cresswell, M Davidson, Geraldine I. Mijares, Richard A Allen, Jon C Geist, M R Bishop
Abstract: The near-term objective of the work reported here is developing a protocol for rapidly mapping CD and edge roughness from high-resolution SEM images of reference-material features patterned on SCCDRM chips. The longer term mission is to formulate a ...
