Week 9

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Testing paramagnetic bead method by isolating parameters

    • magnetic force

    • needle length/diameter

    • needle tip

    • Ground strategy  (sweep, poke, peck, puncture

    • Slide material

Accomplishments from Previous Week

• • Figured out the LABVIEW software glich

  • Attemped pickup of beads

    • Beads free-floating in water

      • works well

    • Beads on glass surface

      • must touch bead

    • Beads on dry surface

      • none completed yet (still adjusting parameters)

    • Beads on dry surface with wet tip

      • Made no difference

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Clear set of experiments to draw strong conclusions

  • Research other ways to magnetize (AC/electromagnet)

  • Microinjector ordered

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • try to get beads from the channels

  • try magnetizing needle using magnetic freezing magnet

  • polarizing light didn't do much to get rid of glare

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • Look into electromagnet

  • Outline parameters

Risks and Areas of Concern

• • Running out of time, need better documented and organized results

Budget (list amount spent and amount remaining)

• • Bought microinjector $2300
