DNA from tomatoes could prevent counterfeit breast implants, say researchers
German scientists claim to have developed a way of identifying counterfeit breast implants by using DNA sequences from tomatoes.
The method was developed by scientists at the Fraunhofer Institute for Applied Polymer Research.
They used DNA sequences from tomatoes as a “permanent marker” to positively identify implants and prevent future counterfeits.
The marker allows implant manufacturers to “tag products” in order to identify genuine products.
“We isolated genomic DNA (gDNA) from tomato leaves and embedded it in the silicone matrix,” explained Joachim Storsberg, a scientist working on the project.
“We used approved siloxanes, which are building blocks for silicone products, to manufacture breast implants.”
The scientists hardened the gDNA in the host silicone at 150 degrees for five hours, before testing it with a polymerase chain reaction and an analytical method called gel electrophoresis. The DNA in the host silicone remained stable and did not degrade.
“Breast implants are made up of components; that is, several silicone polymers that cross-link to form a gel,” added Storsberg.
“The components’ manufacturer now has the option of marking silicones with the encapsulated tomato DNA sequence during the production process. He alone knows the type and concentration of the DNA used.”
