Lab-on-a-Chip

Micro Total Analysis System

Lab-on-a-chip concept enables chemical reagent manipulation (dispensing, mixing, incubation, reaction, analysis) on a very small surface area (1cmx1cm) using extremely small reagent quantities

Advantages:Low reagent volume/low analysis cost Fast results (short reagent diffusion time) High precisionPortability

Microfluidics Risks

Local Israeli Industry just starting to be involved

• Products cost should meet market expectation, namely be sufficiently low



Microfluidics Technology

Materials: Silicon, glass or plastics

Fabrication Methods: Depend on materials

Packaging: Unique issues related to liquids

Simulations: CFD- computational Fluidic Dynamics



MEFS Significance

• Microfluidic MEMS technology has potential

of revolutionizing biochemical/medical sciences

in a similar way as microprocessor has

revolutionized computer science

• Understanding and modeling of micro flow

phenomena is still largely unexplored subject

• There are interesting and still emerging new microfluidic applications meeting vast market needs
