“Shielding” has been impregnated with actual SARS-CoV-2 RNA (coronavirus) from a plasmid construct. This is a safe, non-infectious reagent for SARS-CoV-2 research (NIBSC 19/304), obtained from the National Institute for Biological Standards and Control, UK. SARS-CoV-2 RNA was supplied to me by researchers Dr. Ines Moura and Dr. Jane Freeman at the University of Leeds who are working with SARS-CoV-2 primers and the RNA construct in the development and use of a RT-PCR assay for SARS-CoV-2 detection in faeces. I’ve worked with Dr. Freeman on several previous works and I knew she was undertaking research in this area. We continue to collaborate on the “Collateral Effects” project.
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.
