    Abstract: The present invention provides a method for preventing or repairing damage to a fetal membrane. In one embodiment, the method comprises contacting a fetal membrane with a composition comprising a four-armed catechol-terminated polyethylene glycol (cPEG) and a biocompatible oxidant. In one embodiment, the four-armed cPEG and the biocompatible oxidant are initially contained in separate solutions, and the solutions are mixed to form the composition just prior to or at the same time that the composition contacts the fetal membrane.
