Design of Magnetic Blood Cleansing Microdevices through experimentally validated CFD modeling

Gómez-Pastora J., González-Fernández C., Karampelas I.H., Bringas E., Furlani E.P., Oriiz I., Flow Science Inc., US

Continuous flow bioseparators allow magnetic particles that are properly functionalized so that they get attached to dangerous pathogens, to be easily captured in a buffer solution. Specifically, the unique properties of magnetic particles enable their [...]

Microfluidic Test Target for Photoacoustic Imaging

Schneider P., Eadie N., Christie L., Zhan Y., Siskar T., Koh D., Xia J., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Photoacoustic imaging involves the use of optics (typically a high power pulsed laser) and acoustics (ultrasonics frequency ranges >1MHz) to image a targeted object. Individually, these modalities, being optical and ultrasonic imaging, can be quantified [...]

Additive Manufacturing of Microfluidic Components via Wax Extrusion

Schneider P., Sukhotskiy V., Christie L., Siskar T., Karampelas I.H., Furlani E.P., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Fused deposition modelling (FDM) has been extensively applied in the fields of rapid prototyping and 3D printing, but typically this technique has mostly been used for the fabrication of low melting point plastics. This paper [...]

A compact syringe-assisted vacuum-driven micropumping with a constant flow rate

Wang A., Koh D., Schneider P., Oh K.W., University at Buffalo, US

Abstract In this paper, a simple syringe-assisted pumping method was introduced. Compared with previous study [1], the proposed design does not require pre-designed vacuum chambers, the multiple pumps can be integrated into one device and [...]

Physical and Chemical Transformations of Silver Nanomaterial-containing Textiles After Use

Gorka D.E., Gorham J.M., National Institute of Standards and Technology, US

Nanomaterials have been increasingly used in consumer products and silver nanomaterials (AgNMs) especially have been used for their antibacterial properties. Increased use of AgNMs in consumer goods will result in increased disposal and entrance into [...]

70dB EMI shielding between 10 MHz and 10 GHZ with sprayed metallization of Ag

Stremsdoerfer S., Jetmetal Technologies, FR

This presentation starts with the description of a new direct chemical plating method for silver, called the JET METAL (JMT) process and of the JET SELECTIVE process, which allows to obtain a selective metallization on [...]

Exposure Assessment Framework for Materials Selection in Consumer Products

Liong M., Exponent, Inc., US

The use of exposure and risk assessment methodologies is crucial in materials selection for consumer products, particularly those involving long-term dermal contact. While biocompatibility test procedures designed for medical devices, such as those described in [...]

A novel fabric softener system to make the softness and water wiping effect compatible.

Igarashi T., Uematsu J., Onda T., Nakamura K., Kao Corporation, JP

It is known that the softness of fabric is realized when fabrics softener is used after washing, and it is also well known that the water-absorbency of the fabrics is decreased as an unfavorable side-effect. [...]

Characterizing the transplanar and in-plane water transport property of fibrous materials under different sweat rate: Forced Flow Water Transport Tester

Tang K.P.M., Chau K.H., Kan C-W, Fan J.T., The Hong Kong Polytechnic University, HK

The water absorption and transport properties of fabrics are important in determining the thermophysiological comfort of apparel and health-care products, especially for sportswear and protective clothing. In the textile industry, a number of water absorption [...]

Characterizing the stickiness property of fibrous materials under wet skin surface: Textile Friction Tester

Tang K.P.M., Chau K.H., Kan C-W, Fan J.T., The Hong Kong Polytechnic University, HK

People sweat a lot when staying in hot environment or exercising. The presence of moisture within fabric-skin interface will cause sensorial discomfort. When applying pressure and friction on wet skin surface, it may lead to [...]
