PAHs and the Universe location:Toulouse date:31 May - 4 June 2010
In this contribution I review the PAH-DIB hypothesis. Firstly, I list several properties of PAHs and their behaviour and expected signatures in space. Next, I give an overview of the current observational insights on the DIB carriers. I conclude with a brief description of recent results on the search for the DIB carriers and the prospects we have for identification.
