This article discusses the possibility of the fabrication of a highly sensitive sensor based on single-walled carbon nanotubes surface modified with functional amino groups (-NH2). The sensor potential for detection of alkali (sodium. lithium. and potassium) metals was investigated. https://www.roneverhart.com/Necco-Halloween-Snack-Size-Candy-Buttons-Strips-Wrapped-32-Piece-Bag/
