César de la Fuente of the Perelman School of Medicine spoke about his work, conducted in collaboration with the School of Engineering and Applied Science, developing a rapid, at-home COVID-19 test. “It all works through these chips that we’ve generated. They’re very small. You can make them out of different materials: paper, cardboard,” he said. “You can put your saliva sample onto the chip, and you can connect it to this little machine, and then you connect it to your phone.”
