The PAD (Paper Analytical Device) Project is an attempt to provide affordable and quick drug-testing that can be performed in developping countries to check the legitimacy of different medicinal products. The device utilizes a paper strip that is able to detect almost instantly the grade of the pharmecutical products to ensure counterfeits or poorly made substitutes don't find their way into the bodies of patients.
Often times poor grade medicine will find its way into developing countries due to not enough funding going into checking the product quality. The PAD strips are a paper test developed by chemist Marya Lieberman that features 12 colored lanes that change hues depending on the chemicals featured in the product. The test can help doctors and professionals scan medicine quality prior prescribing to patients.
