Suture-free methods for the delivery of cardiac patches in vivo. (A) a: CHI film. b&c: Rose Bengal is added to the CHI film making a non-conductive photoactivated patch (nc-Patch). d: PANI is immobilized into the nc-Patch, making a conductive patch (c-Patch). e: Transplantation of the c-Patch into the rat heart through photoadhesion. f: Explanted heart after two weeks in vivo.

(B) Suture-free GNR-based cardiac patch. a: Synthesized GNRs. b: SEM image of electrospun albumin scaffolds. c: SEM image of incorporated GNRs into the fibrous scaffolds. d: Scheme illustrating the transplantation of cardiac patch into the beating heart by NIR radiation. e: Integration of the cardiac patch with the rat heart. f: SEM image of the integrated patch and the heart tissue.
