PLASTIC MICROFLUIDICS: TRANSFORMATIVE TECHNOLOGY FOR TOMORROW

Patrick Mather , Sadhan Jana , Prithu Mukhopadhyay, May 2009

Abstract #1: Design, Fabrication and Applications of Polymer Microfluidic Biochips Microtechnology is initiated from the electronics industry. In recent years, it has been extended to micro-electro-mechanic system (MEMS) for producing miniature devices based on silicon and semi-conductor materials. However, the use of these hard materials alone is inappropriate for many biomedical devices. Soft polymeric materials possess many attractive properties such as high toughness and recyclability. Some possess excellent biocompatibility, are biodegradable, and can provide various biofunctionalities. I will first give a brief overview of major activities in our center on micro/nanomanufacturing of polymeric materials and microfluidics. An enzyme immunoassay chip will be discussed as an example for a low-cost and mass-producible lab-on-a-chip platform for molecular and biological analyses. The platform is a microfluidic CD for Enzyme-Linked Immunosorbent Assays (ELISA) that reduces cost, accelerates results, and improves reliability of analyses for food borne contaminants, cancer diagnoses and environmental contamination. The presentation will cover (1) optimization and integration of the critical microfluidic and biochip packaging methods developed for CD-ELISA applications, (2) development of manufacturing and detection protocols for the CD-ELISA chips, and (3) evaluation of the performance of CD-ELISA's by validating testing for food borne pathogens and cancer cytokines.?ÿ ?ÿ Abstract #2: Bio-applications of Microfluidics: A flexible microfluidic device to characterize bacterial biofilms We characterize the viscoelasticity of bacterial biofilms by means of a flexible microfluidic device. The biofilms are comprised of Staphylococcus epidermidis and Klebsiella pneumoniae.?ÿ The presence of implanted foreign bodies such as central venous catheters is a key risk factor for infection by bacteria of this kind.?ÿ Because of the sensitivity of biofilm properties to environme

MICROFLUIDICS FOR RAPID PERSONALIZED DIAGNOSTICS – ARE THERMOPLASTICS THE ULTIMATE SOLUTION?

E. Roy , M. Geissler , T. Veres , M.M. Dumoulin, May 2009

The development of disposable microfluidic devices for rapid point-of-care applications has become central to progress in medical diagnostics and a variety of other fields. Microfluidics is the technology of engineering flow at the micrometer scale, making it possible to perform multiple operations on a single chip. The use of these systems is attractive because they promote reduced sample consumption and analysis time without being restricted to standard laboratory settings. To this end, lab-on-a-chip (LOC) systems have mostly been shown to function in conceptual ways, yet their commercialization and widespread use has been hindered by a number of challenges, which include materials and low-cost fabrication technologies as primary concerns.

NEW STRUCTURAL POLYMER FOR METAL REPLACEMENT APPLICATIONS

Dr. Mike Zimmerman , Chris Lee , Dan Ward , Eric Paszkowski , Rick Boisjoly , Jim Elliott , Michael McGee, May 2009

Recent developments based on a novel thermoplastic Liquid Crystal Polymer (LCP) molecule and compound formulation have led to a new material which can exceed the properties of traditional plastics and demonstrate metal-like properties for structural applications. Developed with a very high modulus (>20,000MPa), tensile strength (125 MPa) and an extremely high strength-to-weight ratio, this material is isotropic and has a tailored Coefficient of Thermal Expansion (CTE) of 17x10-6/?øC matching aluminum and steel. The material has balanced dimensional stability and ultra-low shrinkage (0.05%) with high temperature stability up to 420?øC. These metal-like properties have been identified as a metal replacement material for structural applications in a variety of applications and markets.

Evaluation of Fusible PVCTM Pipe as a Sustainable Infrastructure Solution

Bob Walker, May 2009

As issues regarding environmental protection and sustainability have moved higher on public and political agendas, the demand for PVC pipe has also risen. The current North American market for PVC pipes and fittings exceeds six billion pounds annually and PVC pipes account for the majority of new water and wastewater pipelines. Indeed, the PVC pipe industry owes much of its success to environmentalists and the environmental movement. More importantly, our environment has benefited immensely as a result of the widespread use of PVC pipe.

Liquid calcium zinc stabilizers-Sustainable liquid stabilizers for flexible PVC.

Ben Labovitz, May 2009

Calcium zinc liquid stabilizers can replace other mixed metal stabilizers in flexible PVC compounds. Ca/Zn liquids are a sustainable and low toxicity option compared to barium, cadmium, and tin based stabilizers.
