Langmuir and Langmuir-Blodgett films from photoactive derivatives of DNA nucleobases

The versatility and many appealing properties of DNA nucleobase derivatives have made them the target of investigations for use in a wide range of possible applications: from medicine to novel materials for nanotechnology and biocompatible electronics. By modifying a nucleobase with a photoactive moiety, one is able to control the binding between nucleobases by irradiating the molecules with light of specific wavelengths.

In this webinar:

  • Learn from the results of the measurements of surface pressure, surface potential, and absorption of Langmuir films from photoactive guanosine derivatives and what the behaviour of each of these tells about the film.
  • Get a comparison of characteristic thermal cis-trans relaxation times in solution, in Langmuir films, and in Langmuir-Blodgett films. 
  • See an analysis of the behaviour of surface pressure in Langmuir films from an azo-functionalised guanosine derivative during irradiation with UV light.

Presentation by Matjaž Ličen

Matjaž Ličen, Jožef Stefan Institute, Slovenia will present the results of their studies of Langmuir and Langmuir-Blodgett films from lipophilic derivatives of nucleobases with an emphasis on the behaviour of films from azo-functionalised lipophilic guanosine derivatives and their response to irradiation with light that triggers photoisomerization.
