Reference number : GC-2017-Q1-00489, amendment number : , agreement type : G, recipient legal name : Branda, Neil (Simon Fraser University), recipient country : CA, recipient province : nan, recipient city : British Columbia|Colombie-Britannique, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : The goal for this university-industry collaborative project is to develop a dynamic ink system that can be_x000D_
applied to the skin under commonly used sunscreen products and indicate to the user when the sunscreen has_x000D_
worn off and when to reapply it. The ink will be based on microencapsulated photoresponsive dye molecules_x000D_
that will change from colourless to coloured when exposed to the UVB radiation in sunlight. The sunscreen_x000D_
worn on top of this stamped ink will block the UVB radiation and prevent the ink from colouring. When the_x000D_
sunscreen wears off, the UVB will reach the stamp, activate the photochromic dyes and become coloured._x000D_
Reapplication of the sunscreen will block the activating light and the stamp will return to its originally_x000D_
colourless state._x000D_
Second generation systems will not only provide visual feed back to the user about the need to reapply the_x000D_
sunscreen, they will also act as dosimeters, providing information about to the total amount of radiation_x000D_
received._x000D_
The collaboration between the Branda group at 4D LABS and this local Canadian company will help develop_x000D_
new materials and methods to overcome an important health problem and provide better guidelines about using_x000D_
