World Health Organization approximates that 10% of medical products in developing nations are counterfeit or “substandard,” while a United Nations health report suggests that nearly 500,000 individuals in sub-Saharan Africa lose their lives every year due to falsified medications.
Identifying rapid, straightforward, and affordable methods to detect counterfeit drugs is becoming more critical, and investigators from the University of California, Riverside have crafted a possible solution. In a study published in Analytical Chemistry, the researchers introduced a device for detecting counterfeit drugs that utilizes technology from an unexpected origin: a toy robot.
Employing a basic sensor designed for a toy, the UC Riverside innovation gauges the quantity of light reflected by the particles released when a tablet is dissolved in water. Given that legitimate medications are strictly regulated, pills of the same type will disintegrate uniformly each time, contrasting with other pharmaceuticals. By analyzing the quantity of particles released over time, scientists can establish what they refer to as a pill’s “disintegration fingerprint” (DF). This can be used to assess the legitimacy of a drug, as a counterfeit will possess a different fingerprint.
