摘要 |
Molded polymer structures, including tubes, plates, cards, bottles, etc. are formed with doped, silica nanoparticles on or with in the polymer matrix. Prior to the thermoforming operation, the nanoparticles may be doped with single or multiple signal producing molecules, which are detectable by optical, electrical, and/or magnetic means. The nanoparticles may be visible or invisible to the naked eye. |
