Abstract:Novel biosensor architecture based on nanocrystalline cellulose (NCC)/CdS quantum dots (QDs) nanocomposite was developed for phenol determination. This nanocomposite was prepared with slight modification of nanocrystalline cellulose (NCC) with cationic surfactant of cetyltriammonium bromide (CTAB) and further decorated with 3-mercaptopropionic acid (3-MPA) capped CdS QDs. The nanocomposite material was then employed as scaffold for immobilization of tyrosinase enzyme (Tyr). The electrocatalytic response of Tyr… Show more
“…Enzymatic biosensors have largely demonstrated excellent analytical applicability for the detection of targets that are involved either as substrates or inhibitors in the enzymatic reaction in which the sensor is based. Specifically, biosensors based on polyphenol oxidase (also called tyrosinase) allow for the determination of phenolic compounds as substrates of this enzyme (such as catechol, phenol, tyrosine and dopamine), [1][2][3][4][5][6][7][8][9] as well as a number of inhibitors (such as benzoic acid among others). [10][11][12][13] Different strategies have been reported for the construction of this sort of biosensors, mainly involving the immobilization of the enzyme by distinct approaches.…”

“…Phenol is one of the toxic phenolic compounds that can be harmful to plants, animals, and humans. (64)(65)(66)(67)(68)(69) Exposure to phenol over its permissible level can lead to symptoms such as vomiting and diarrhea, and further exposure can cause kidney, lung, and liver malfunction. (70)(71)(72)(73)(74)(75) Consequently, it has drawn researchers' attention, leading to the rapid development of sensors for its detection.…”
“…Abd Manan et al [ 289 ] successfully developed biosensor based on nanocrystalline cellulose (NCC)/cadmium sulphide (CdS) quantum dots (QDs) nanocomposites for phenol determination. They modified the NCC with cationic surfactant of cetyltrimethylammonium bromide (CTAB) and further decorated with 3-mercaptopropionic acid (MPA) capped CdS QDs as a scaffold for immobilisation of tyrosinase enzyme (Tyr).…”

Wood-based industry is one of the main drivers of economic growth in Malaysia. Forest being the source of various lignocellulosic materials has many untapped potentials that could be exploited to produce sustainable and biodegradable nanosized material that possesses very interesting features for use in wood-based industry itself or across many different application fields. Wood-based products sector could also utilise various readily available nanomaterials to enhance the performance of existing products or to create new value added products from the forest. This review highlights recent developments in nanotechnology application in the wood-based products industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
