We would like to see the developement of a multitude of laboratory modules geared for use in undergraduate environments. Module information can go from simple ideas of projects to fully detailed experiments with sample data, etc.

We are slowly filling in these modules with protocols and data.

Modules outlined in AJP paper

Calibration and Characterization
E.coli rotation
DNA tether stretching
Fluorescent Microtubules

User submitted modules

The following module combines aspects of the calibration and E.coli modules to make a streamlined 2 hour course for an optical trap demonstration. It includes the calculation of the coefficient of drag for a sphere using an optical trap. Developed by Dr. Barbara Hughey & Dave Appleyard for the Women in Technology Program at MIT.
