Skin, the largest and most exposed organ of the human body, harbors an incredible diversity of molecules that have a number of origins. Such origins include but are not limited to human cells, microbes that live on the skin, and the surrounding external environment. Our daily routine as well as all of the soaps, creams, and moisturizers that we apply on the skin also contribute to the chemical composition of human skin.
In the Dorrestein lab at the University of California San Diego, we have decided to develop a mass spectrometry based approach in combination with computational tools to study the chemical composition of human skin surface.

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.
