To create the colorized scans, the researchers fitted a special detector on a conventional electron microscope. The researchers then selectively “painted” structures such as proteins, membranes, and cells with various “rare earth” metals, including lanthanum, cerium and praseodymium in the form of a chemical solution. When these specimens were scanned by the modified microscope, the stream of electrons lost by the metallic elements were interpreted as color.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
