Abstract

Carbon/Nafion® nanocomposite thin films developed through a low-cost procedure were shown to function as high-sensitivity, low-noise, high-throughput laser desorption-ionization mass spectroscopy substrates for small molecule detection without the need of organic matrices. Our nanocomposite approach combines the strong light absorption feature of amorphous carbon with Nafion®'s efficient protonating capability to yield superior laser desorption-ionization.
