Jubilee of Precision Ellipsometry

Event Date: 19 Dec 2018 (Wednesday) - 19 Dec 2018 (Wednesday)

Kinesis Building, Seminar Room 3, Level 7

Time :02:00 - 03:30

Ellipsometry is analytical technique that determines properties of thin films by measuring changes of light polarisation reflected from the film.  It gains its sensitivity by measuring phase shift between components of polarisation rather than intensity.  Precision ellipsometry (PREL) uses polarisation modulator that makes it even more sensitive.  With polarisation modulator designed and made in IMRE, PREL system has sensitivity in the range of microradians.  This translates to sensitivity of 0.01 nm of organic layer on silicon.

In IMRE, PREL was used for quantitative real-time measurement of interactions, binding and unbinding of various molecules and multilayers, ranging from small molecules (amino-silane), polymers and polyelectrolytes to bio-molecules, proteins, antibodies and aptamers.  The results of these studies, findings and discoveries will be presented at the seminar. There will also be a ‘live’ demonstration on measuring molecular attachments using a portable PREL system.
