SYSTEM AND METHOD OF USING PLASMONIC NANOPARTICLES FOR ANTI-COUNTERFEIT APPLICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240054841 titled 'SYSTEM AND METHOD OF USING PLASMONIC NANOPARTICLES FOR ANTI-COUNTERFEIT APPLICATIONS

Simplified Explanation

The patent application describes a method of using nanoparticles for anti-counterfeit applications by creating unique nanofingerprints based on the position and color of non-spherical nanoparticles on a substrate.

  • Select at least one non-spherical nanoparticle for anti-counterfeit application.
  • Place the nanoparticle on a substrate.
  • Shine light on the nanoparticle to determine its position and color.
  • Define a nanofingerprint based on the position and color of the nanoparticle.
  • Recognize the nanofingerprint for authentication purposes.
      1. Potential Applications
  • Anti-counterfeit measures for products and documents.
  • Security features for currency and identification cards.
      1. Problems Solved
  • Counterfeiting of products and documents.
  • Unauthorized replication of sensitive materials.
      1. Benefits
  • Enhanced security and authentication.
  • Difficult for counterfeiters to replicate nanofingerprints.
  • Reliable and cost-effective anti-counterfeit solution.


Original Abstract Submitted

a method of using at least one nanoparticle for an anti-counterfeit application including selecting the at least one nanoparticle having a non-spherical configuration; providing the at least one nanoparticle on a substrate; providing a light to the at least one nanoparticle; determining a position of the at least one nanoparticle based on providing the light to the at least one nanoparticle; determining a color of the at least one nanoparticle based on providing the light to the at least one nanoparticle; defining a nanofingerprint based on the position and the color of the at least one nanoparticle; and recognizing the nanofingerprint.
