The cover image represents an inside view of a laser‐activated gold nanorod/chitosan film. Gold nanorods dispersed throughout the polymeric chitosan matrix absorb incident near‐infrared laser light. The photothermal conversion from the gold nanorods activates the surrounding chitosan strands to mediate functional adhesion with biological tissue, as discussed in work reported on p. 4313 by Paolo Matteini...
Biocompatible chitosan/gold nanorods films are fabricated and tested as laser‐activatable adhesives. When exposed to near‐infrared laser light the nanoparticles carry out efficient photothermal conversion, which activates the polar groups of chitosan strands and mediates functional adhesion with a biological tissue. This technology may enable a number of key applications in medicine including tissue...
