    摘要： The present invention provides a method of sensing pressure in a region of interest by providing a plurality of metallic particles operatively associated with one another in the region of interest (for example, wherein the metallic particles sustain a plasmon upon excitation), and with the metallic particles configured or positioned in relationship to one another so that a physical property of the particles (for example, the energy of the plasmon) varies in response to pressure; measuring the physical property of the metallic particles that varies in response to pressure; and then determining the pressure in the region of interest from the detected physical property (e.g., resistance, energy of the plasmon). Compositions, articles and formulations for carrying out the method in industrial and biomedical applications are also described.
