We report the development, as well as the in vitro and in vivo testing, of a sprayable nano-therapeutic that uses surface engineered custom designed multi-armed peptide grafted nanogold for on-the-spot coating of infarcted myocardial surface.

When applied to mouse hearts, 1 week after infarction, the spray-on treatment resulted in an increase in cardiac function, 2.4-fold, muscle contractility, and myocardial electrical conductivity. The applied nanogold remaining at the treatment site 28 days post application with no off-target organ infiltration. Further, infarct size in the mice that received treatment was found to be <10% of the total left ventricle area, while the number of blood vessels, pro-healing macrophages, and cardiomyocytes increased to levels comparable to that of a healthy animal.

Our cumulative data suggests that the therapeutic action of our spray-on nanotherapeutic is highly effective and in practice its application is simpler than other regenerative approaches for treating the infarcted heart.
