A medical delivery device includes a first compartment configured to hold at least a portion of an activator that activates one or more molecular nanomachines. The first compartment includes a first wall that includes a first ferrous material, where the first wall is configured to disintegrate in response to first electromagnetic radiation received by the first ferrous material such that the activator activates the one or more molecular nanomachines. The device includes a second compartment configured to hold the one or more molecular nanomachines, wherein the second compartment includes a second wall that includes a second ferrous material, and wherein the second wall is configured to disintegrate and release the one or more molecular nanomachines into a patient in response to second electromagnetic radiation received by the second ferrous material.
