About the cover

December 2011 Volume 3 No 12

The cover image shows an artist's impression of cells growing in a photochemically modifiable hydrogel matrix. In the system described by Cole DeForest and Kristi Anseth, the hydrogel is formed using a biocompatible copper-free click reaction. It is then modified using a combination of two orthogonal photochemical reactions to investigate how cells spread and form interactions in response to various biochemical and biomechanical stimuli during growth.
