To give you an idea of how micro this video is, those dots you see moving diagonally toward the top of the screen are individual white blood cells. What you’re looking at is a microchip that sorts out white blood cells from a blood sample. It makes a great visual, but more importantly, it could seriously improve the way we diagnose disease.
Researchers at MIT used the same process that goes on inside your body to attract white blood cells away from the general blood flow. They coated tiny channels (the diagonal stripes in the video) with a sticky molecule called P-selectin, which your body uses to attract white blood cells to injured tissue. As blood passes from left to right along the bottom, white blood cells filter out, and roll away along the P-selectin coated ramps.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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.
