Objective

Test the conductivity of our nanoparticles that we created using probes

Description

  • four leads close enough that with purple solution, that when we place on leads it will connect all four leads. on piece of teflon
  • find the conductance of gold nanoparticles
  • start to investigate.
  • cut out pieces of platium wire
    • make them square or rectangular small as possible fit wire underneath comfortably
    • Wire has to make contact with these squares. wire 1" to .5"


steps(go in this order)

1. put down conductive epoxy on teflon (epoxy holds wire to teflon along with foil. wire connected to foil)

2. put down wire

3. put down square foil


note: need to known the area of each foil strip, should be as close as possible. between the two middle ones, close as possible.

Today set and let epoxy dry, get some protein and particles in small volume. Deposit all over the foil. Electrical contact. Foil can not be touching, but as close as possible. Becuase we do not know the strength of the conductivity between nanoparticles.

Why is a 4 point prober better than a 2 point probe?

Notes

This area is for any observations or conclusions that you would like to note.


Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
