Susana Palma & Cecรญlia Roque have created sustainable, unclonable security tags to fight counterfeiting and protect consumers worldwide 
.
โข Made of 80% biodegradable materials
โข Unique optical โfingerprintsโ that cannot be replicated
โข Easy to verify with a smartphone or microscope
โBy combining gelatin with molecules that manipulate light, we created a material with unique optical properties, like fingerprints, that cannot be replicatedโ, explains Susana Palma, first author of the study.
โA simple, natural material like gelatin can be turned into a powerful tool against counterfeiting while contributing to a more sustainable futureโ, says Cecรญlia Roque, coordinator of the study and UCIBIO Director.
