Power Puff Girls

This week we finished building the housing and attaching all the components together. We also tested our neodymium magnets for the first time, completed our mid-semester presentation, and starting creating test-protocols. Figure 1 shows our completed prototype Figure 2&3 shows the results of using neodymium magnets. They worked very well, leaving no observable particles in the end product, only slight discoloration of the water. Figure 1. Figure 3. Figure 2.

This week, we want to have the whole project working, but so far, we have the recirculation plate tilting controlled by the motors.  The following link shows the movement of the motors and the recirculation plate.  recirculation and motors movement .  We have yet to anchor the parts of the pulley system. 

This week, the Power Puff Girls worked on the recircultion device. After developing a new design for this portion of the project, the girls worked to complete building. During the week, parts were made using Solidworks and AutoCAD. The parts will be used in the apparatus to cause a tilting that will cause the blood in a bag to move and mix the blood in order to increase the binding probability of the nanoparticles and tumor cells. The devices can be seen in figures 1 and 2. Figure 1: Solidworks drawings of the pulley used for the recirculation device.  Figure 2: An AutoCAD drawing of the plate used in the recirculation device. During the week, the girls spent time in the shop to build the container for the whole project and the attachments for the printed parts and the box. There was some delay in the process as one of the tools needed for processing was loaned out earlier in the week. The tool should be back in the shop on Monday February 12, and another blog wi...

This week, the Power Puff Girls mainly worked on coming up with a design for the re-circulation device. In doing so, a better design for the overall apparatus was developed. In the previous blog, you can see the details for the device itself. The basis behind making the design can bee seen in the brainstorming represented in Figure 1. Figure 1: An image of the brainstorming board from January 29, 2018. Starting from the left, there is a list of ideas for re-circulation along with pros and cons for each. The bottom of the whiteboard shows the important factors that the device MUST accomplish. The ideas were then placed under each to see which idea was able to complete the needed task. In the center is a schematic of what the entire project needs to do. It is important that there is not too much blood outside of the body at a given time. The design is set up so that the maximum volume of blood outside the body is 1 pint. This value was determined from the fact that 1 pint is wha...
