(a) Survival yield of BP ions desorbed from various carbon substrates (Buckminsterfullerene = C₆₀, Multiwalled Carbon Nanotubes = CNT, nanoporous graphitic carbon = PGC, non-porous graphite particles = G, highly oriented pyrolytic graphite = HOPG, Nanodiamonds = ND) in a range of laser fluencies, adapted with permission from [57]. Copyright American Chemical Society, 2009; (b) Survival yields of 4-methyl-BP ions in desorption/ionization from SiNWs, DIOS, and MALDI. All solid symbols are for a N₂ laser (λ = 337 nm, 4 ns pulse length), and all hollow symbols are for Nd:YAG laser (λ = 355 nm, 22 ps pulse length): (red) perfluorophenyl (PFP)-derivatized SiNW surface, (blue) PFP-modified DIOS, and (black) MALDI from CHCA matrix, adapted with permission from [54].
