Fast detection of counterfeits
In most cases, the composition of counterfeit drugs considerably differs from the original formulations: active ingredients, mixing ratio of excipients, coatings, packaging materials can all differ.
This becomes evident in the vibrational spectrum of the particular products. Thus, authenticity checks of products can easily be performed on the basis of their Raman spectra. Reference spectra of the original formulations are stored and the spectrum of the product under examination is compared with it.
Depending on the packaging of the product, this test can often be performed without destruction: Raman spectra can also be absorbed through transparent packaging such as blister foils.
