Mixed-ligand nanoparticles of chlorobenzenemethanethiol and n-octanethiol as chemical sensors

Gold Nanoparticles in Chemical and Biological Sensing

“…435,436 For example, AuNPs of two different thiol ligands have been fabricated by Kim et al 436 that showed different chemical selectivities and produced rapid and reversible responses towards the vapors of 1-propanol, acetone and cyclohexane. AuNP-dendrimer composites have also been explored in vapor sensing.…”

An assessment of sensing technologies for the detection of clandestine methamphetamine drug laboratories

“…These materials include carbon nanotubes [59,60], nanoparticles [61], nanorods [62][63][64][65][66], nanobelts [62,67], nanowires [62,[68][69][70], and nanofibers [71][72][73] made both from polymers and semiconductors. Their high surface area to volume ratio offers the possibility of building highly sensitive devices with low detection limits.…”

Controlled Synthesis and Tunable Upconversion Luminescence of NaYW<SUB>2</SUB>O<SUB>8</SUB>:Yb<SUP>3+</SUP>/Ho<SUP>3+</SUP> Nanocrystals

“…[1][2][3][4][5][6][7][8][9][10][11][12] With rapidly shrinking sizes, micro/ nanocrystals usually exhibit novel physical and chemical properties due to their extremely small sizes and relatively large specific surface areas. [13][14][15] Upconversion (UC) is an anti-Stokes process where long wavelength radiation is converted to shorter wavelength via a two-photon or multi-photon mechanism. 16 UC phosphors have been extensively studied due to their potential applications in three-dimensional displays, solar cells, and solid-state lasers.…”
