Abstract: It is intended to provide a method for delivering a drug such as a gene to a tissue or organ for transplant such as skin by use of a laser-induced stress wave (LISW) and thereby producing a high-performance tissue or organ for transplant with a high survival ability and to provide an apparatus for carrying out the method as well as a high-performance tissue or organ for transplant produced by the method. The present invention provides a method for delivering a drug to a graft of a tissue or organ for transplant, comprising applying a drug to a graft of a tissue or organ for transplant and applying, to the graft, a stress wave induced by the laser light irradiation of a light absorber provided in proximity to the graft, wherein the light absorber is made of a substance capable of absorbing a laser light and generating a stress wave.
