Abstract: Systems and methods for detection of an amphiphile at a liquid crystal interface include the production of circular polarized light. A system 100 for detecting an amphiphile at a liquid crystal interface comprises a source of white collimated light. A circular polarizer is included for circularly polarizing incoming white light. Polarized white light passes through to an LC grid including a suspended LC film and a solution in contact with the LC grid at a surface. A spectrophotometer optically detects the presence of an amphiphile at the surface by determining a change in birefringence exhibited by the suspended LC film. A method for detecting amphiphiles at a liquid crystal water interface comprises shining collimated white light on an LC cell including an LC film, polarizing the white light with a circular polarizer, adding an amphiphile to a solution in contact with the LC film, and optically detecting the presence of the amphiphile by measuring a change in birefringence exhibited by the LC film.
