Surface assembly of nano-metal organic framework on amine functionalized indium tin oxide substrate for impedimetric sensing of parathion

The Cu-MOF-199/single-walled carbon nanotubes modified electrode for simultaneous determination of hydroquinone and catechol with extended linear ranges and lower detection limits

“…The Co-MOF modified carbon paste electrode also showed a wide linear range from 2.5 µmol·L -1 to 0.95 mmol·L -1 with the detection limit of 2.5 µmol·L -1 for the determination of GSH. Deep et al [27] presented the surface assembly of a nanometal organic framework [Cd(atc)(H 2 O) 2 ] n (atc = 2-aminoterephthalic acid) on a 2-aminobenzylamine (2-ABA) modified indium tin oxide (ITO) slide by sequential dipping. The pesticide sensor based on this modified electrode was designed for the electrochemical determination of parathion by the M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 5 electrochemical impedance spectroscopy and its sensitivity was better or comparable to the reported sensors.…”

A review on metal-organic framework: synthesis, properties and application

“…Akash deep et al [157] were the first who A novel approach to develop an inkless and erasable printing medium using MOFs has been demonstrated by synthesizing photochromic MOF [158]…”

Recent Progresses in Nanobiosensing for Food Safety Analysis

“…Amino-carboxyl compounds (based on 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide/ N -hydroxysuccinimide (EDC/NHS)) are most commonly used to functionalize variety nanomaterials [ 52 , 53 ], while metal-S is prevalent to functionalize metal NPs and QDs [ 23 , 54 ]. Other approaches of functionalization include metal-ligand [ 55 ], efficient click chemistry [ 56 ], and SN2 mechanism [ 57 ].…”

“…In addition, immunoassay based nanobiosensing are most common for detecting pesticides in food [ 105 , 106 , 107 ]. The application of nanometal organic framework and other materials can greatly reduce the LOD [ 55 ]. As pesticides are known to impede certain photophysical as well as photochemical functions of nanomaterial, through specific recognition of pesticides by antibodies decorated on nanomaterial, several excellent phenomena have been discovered: pentachlorophenol obstructs electrochemiluminescence of Au nanoclusters/graphene hybrid [ 108 ], acetamiprid decreases enhanced photocurrent produced by electron donor of quercetin in Co-doped ZnO diluted magnetic semiconductor, thiram quenches blue luminescence of Cu 2+ decorated NaYF4:Yb/Tm upconversion NPs fixed on filter paper (monitored by the smartphone camera through a self-written Android program) [ 109 ].…”
