Silicone strips can be useful chemical monitoring devices. They have long chainlike structures that create channels similar in size to the pores in human cell membranes. Pores in the cell membrane could determine which chemicals make it into our cells.
Silicone wristbands are comfortable. They can be worn while sleeping, eating, showering, exercising, petting animals, cooking, and working on a laptop. When they’re removed, they are checked for the presence of different chemicals.
