  • You may find this microrheology tutorial useful. But, then again, you may not.
  • A limited number (2) of optical traps will be set up on Monday. With a little luck, all 6 will be set up by Friday.

  • Here's a link to the presentation I gave last Friday. --Lissa Riley
  • And here are the pictures for the microscope assembly we discussed on Friday as well. - Sergio N.
  • Here is the best piece of advice you will receive on Lab Module 3: design your microscope before you begin constructing it!
  • It is strongly recommended that you:
  1. prepare a decent sketch of your design; and
  2. run it by Heejin or Jae Won before you begin construction.
  • Heejin and/or Jae Won will be in the lab Tuesday from 3:30-5:30, Wednesday from 3:00-6:00, Thursday from 1:00-6:00, and Friday 1:00-5:00
  • Access the course locker from Athena terminals by typing: attach 20.309; cd /mit/20.309/Students or use SecureFX from a non-Athena computer.
