Overall Goals for Senior Design Team:

  1. Quantitative modeling of micro fluidic channel flow
  2. Fluent/Gambit
  3. Time: 40 hours
  4. Resources: Professors, graduate students that have used the software, user groups
  5. Risk:
  6. Time: This could take a lot of time so need to time manage the different duties
  7. Resources: Not able to find the right people to help
  8. Milestones:
  9. Design basic channel with reservoirs
  10. Include nanotube inlet
  11. Include trap dimensions in channel
  12. Design multiple chips
  13. Collect data and compare data for different chips
  14. Definition of Success: Success gauged by completion of milestones
  1. Electrostatic modeling with Maxwell
  2. Time:10 hrs
  3. Resources: Voldman, online tutorials and user groups
  4. Risk:
  5. May not be able to export data to model DEP forces with Matlab
  6. Time: Could take away from other duties if time is not managed carefully
  7. Milestones:
  8. Display cross-section of electric field data at middle of DEP trap
  9. Explore similarities between Maxwell and FEMLAB, which is the actual program used to export the electric field data
  10. Export electric field data from Maxwell to model DEP forces with Matlab
  11. If it is deemed not possible to export data from Maxwell, then look into purchasing license for FEMLAB (now COMOSOL Multiphysics)
  12. Definition of Success:Success gauged by completion of milestones
  13. Modeling DEP forces with MatLab
  14. Time: 30hrs if no issues arise (excludes experiments time to calculate flow rate)
  15. Resources: Voldman and graduate students, proficient MatLab users
  16. Risk:
  17. Time: could take longer to precisely model our setup than expected and reduce the focus from other duties
  18. Resources: MatLab groups not focused on streamforce modeling, Voldman and students no longer supporting the software
  19. Milestones:
  20. Working test example from Rosenthal et al 2005 publication
  21. Simulate DEP model with our chip parameters
  22. Simulate our chip with electric field data from Maxwell
  23. Flow rate analysis between experiments and modeling
  24. Definition of Success: Success gauged by completion of milestones
  1. Collectionand analysis of cell data
  2. Time: Unlimited
  3. Resources: Need viable cells, information about viability tests, what is solution made of and how to make diluted solution, money
  4. Risk:
  5. Time- Devoting too much time and neglecting other duties
  6. Money- Lack of data may lose grant opportunities
  7. Inconclusive data
  8. Availability of cells and running experiments while cells are viable
  9. Milestones:
  10. Trapping cells and data collection (velocity, frequencies, voltages, bubble formation, time between flowing cells, position of cells, etc)
  11. Spectra data
  12. Theoretical analysis
  13. Experimental analysis
  14. Definition of Success: Success will be gauged by completion of milestones
  1. Design (fabrication-Weina) new DEP mask
  2. Time: Coordination with design and fabrication will be time dependent (don’t have a gauge of how long this could take)
  3. Resources: Simulations in Maxwell for electrostatic design specifications, MatLab DEP modeling, Fluent simulations to help design for fluid flow
  4. Risk:
  5. Time- Takes a lot of time from other duties
  6. Money- Need money for materials
  7. Lack of materials- Not able to get materials or too much money
  8. Milestones:
  9. Come up with functional designs
  10. Actually fabricating chips from the design
  11. Definition of Success: Success will be gauged by completion of milestones
  1. Analyze how bubble size affects channel flow
  2. Time: 10 hours
  3. Resources: Taking all the data collected and breaking it into comparable data, program to graph data
  4. Risk: Taking too much time and not focusing on other duties
  5. Milestones:
  6. Collecting relevant data
  7. Organizing data
  8. Plotting data
  9. Definition of Success: Success gauged by completion of milestones
