A candy that can tell if you're pregnant? The invention that could change everything

A US student is developing a pregnancy test candy designed for women with visual impairments. The candy is intended to detect the hCG hormone in saliva through tactile bumps on its surface. The development has not yet been clinically proven.

A US student, Rau, is developing a pregnancy test candy designed for women with visual impairments. The product, called TACT, is intended to detect the pregnancy hormone hCG in saliva using tactile bumps on the candy's surface. Bumps on both sides indicate a positive result, on one side a negative result, and no reaction indicates an invalid test. The development began last January under the guidance of a biomedical engineering expert. So far, the shape and texture have been tested, but the hormone detection mechanism is still under development. The next step is to integrate a DNA component that will bind to the hormone, followed by clinical trials and regulatory approval. The goal is to enable accessibility and privacy without the need for a smartphone or app.
