Dr. Kate Biberdorf Explains How At-Home COVID Antigen Tests Work
Learn about the chemistry of the at-home antigen tests from Dr. Kate Biberdorf in this video from WIRED on YouTube:
Over the past two years, you’ve likely taken a Covid rapid antigen test. A unique, biochemical reaction involving saline, tiny particles of gold, and paper with antibodies, is helping to give us quick and relatively accurate results.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
