Disclosed is a trace detection device of a biological and chemical analyte, including a metal substrate, a periodic metal nanostructure on the metallic substrate, a dielectric layer on the periodic metal nanostructure, and a continuous metal film on the dielectric layer. Tuning the thickness of the dielectric layer and/or the continuous metal film to meet the laser wavelength can shift the absorption peak wavelength of the sensor, thereby further enhancing the Raman signals of the analyte molecules.

A method of regenerating a phase-change sputtering target for optical storage media. First, a used powder-metallurgy sputtering target composed of a target material, an adhesion material, and a backing plate is recycled. Then, the target material is separated from the backing plate. Then, the target adhesion material is scraped from the recycled target material Thereafter, the surface of the recycled target material is processed. Finally, the backing plate, a new adhesion material, the recycled target material, and new powders are placed in a vacuum thermal-pressure furnace in sequence to perform a thermal-pressure sintering process. This completes a new phase-change sputtering target
