Highly sensitive sensor probe development with ZCCO nano-capsule composites for the selective detection of unsafe methanol chemical by electrochemical technique

Highly selective and discriminative detection of small alcohols based on a dual-emission macrocyclic samarium complex

“…For instance, alcohol, found in an early period of human society, has played very important roles in liquors, 2 disinfectants, 3 and fuels. 4 Methanol is a crucial chemical raw material to produce formaldehyde, 5 formic acid, 6 pesticides, 7 and so on. Polyols, the 1,3-PDO, 8 are commonly used as intermediates in drug synthesis, and glycerol 9 is commonly used as humectants in skincare products.…”

“…In particular, small alcohols (methanol, ethanol and propanol) are frequently used organic solvents for various syntheses in chemical industries. 2–9 Nowadays, the development of reliable, rapid, selective, sensitive and simple techniques for detecting small alcohol has been an urgent demand not only in traditional brewing, pharmaceutical, clinical and chemical fields but also in booming alcohol-based renewable energy industries. After many years of great efforts, researchers have reported many technologies for detecting small alcohols using sophisticated instruments, such as the GC, 10 HPLC, 11 FT-IR, 12 NIR, 13 MS, 14 NMR, 15 Raman spectroscopy, 16 and flame ionization detectors.…”
