This week, our group worked on finding the tools to use for design testing and we made a list to order. The following are the parts that we will order for testing. 

1. Abrasion-Resistant Polyurethane Tube for Air, 1/8" ID, 3/16" OD for $8.50

Figure 1: tubing 

The tubing's diameter has to be approximately equal to the vein's. This is to ensure  that the velocity doesn't increase in the tube because returns into the body. 

2. Graduated Glass Beaker, 20.3 oz./ 600 ml

beakers will be helpful in testing since water (symbolizing blood) will be drawn from one beaker to another

3. SC947 Iron filings-12oZ

Iron oxide shavings will be used instead of magnetic nanoparticles. for testing the magnetic field of the permanent magnet. We are still looking for the smallest size  to fit the qualifications of nanoparticles better. 

4. Plastic Syringe with Luer Lock Tip, 0.17 oz. Capacity and Reusable Stainless Steel Dispensing Needle with Luer Lock Connection, Blunt, 16 Gauge, 1/4"

Figure 4 showing a syringe and needle 

syringes will be used to draw water from the beaker and returning it. Syringes with needles will be used to inject nanoparticles into the flow. 

Other parts that we will need to buy are tube fittings, Velcro, and a small pump (Right now, testings will be done using gravity to drive water). 

Also, for testing, We will be using Dr Xi's magnet until we design and print our own.

This week, we also worked on practicing comsol geometry, fluid flow, and magnetic fields.
