A series of articles and techniques for controlled pharmaceutical delivery within a patient is described. An article includes at least one cavity having an interior dimension equal to a resonant mode of electromagnetic radiation to which the article is exposed. A standing wave is created within the cavity, causing a change in a diffusion characteristic of at least one component of the cavity, in turn causing release of a pharmaceutical from the cavity into an area of the body surrounding the article. Low-energy, non-destructive electromagnetic radiation, such as visible or near-infrared light, can be used. |
