Light-induced facile and efficient synthesis of color-variable lignin-based gold nanoparticles and its application as Pb2+ sensor

Red gum-capped gold nanoparticles for electrochemical sensing of bromocresol purple in water

“…18–23 For example, AuNPs are used as electrochemical probes for the detection of many analytes such as cortisol, 24 diethylstilbestrol, 25 dopamine, 26 norepinephrine, 27 serotonin, 28 boron, 29 copper( ii ) ions, 30 arsenic ions, 31 phosphates, 32 and Escherichia coli . 33 AuNPs can be fabricated by different methods such as laser-induced photochemical synthesis, 34 plasma-based instant synthesis, 35 UV-induced decomposition, 36 chemical vapor deposition, 37 and chemical reduction. 38 Chemical reduction is considered the most widely used method for the synthesis of AuNPs.…”

UV‐Induced Oxidation Preparation of Multi‐Functional Lignin‐Based AgNPs and its Application for Conductive Coating, Antibacterial Enhancement, and Product Separation

“…[7] Therein, the preparation of biocompatible AgNPs has been reported more and more. Lignin is one of the most abundant components in plants, [8,9] and a large number of oxygen-containing functional groups make it reducible and dispersible. [10,11] Researchers have conducted extensive researches on the preparation of AgNPs using lignin as reducing and dispersing agent.…”
