“…While, when b-CD functionalized CNHs were modified on GCE, b-CD was found to be able to further induce the amplification effect towards ECL emission of luminol owning to the rich hydroxyl groups on the b-CD. 11 After the supermolecular interaction between naringin and b-CD occurred naringin molecules were introduced on the sensing interface. The inclusion complex formed on the sensing interface thus led to some changes on the kinetics of heterogeneous electron transfer, surface terminal functional groups and the charge density.…”

A molecularly imprinted polymer (MIP) based on free-radical polymerization was prepared with 1-(N,N-biscarboxymethyl)amino-3-allylglycerol and N,N-dimethylacrylamide as functional monomers, N,N-methylene diacrylamide as the cross-linker, copper ion-clonazepam as the template and 2,2-azobis(2-methylbutyronitrile) as the initiator. The imprinted polymer was characterized by Fourier transform infrared spectroscopy, elemental analysis, thermo-gravimetric analysis, and SEM. The MIP of agglomerated microparticles with multipores was used for SPE. The imprinted polymer sorbent was selective for clonazepam. The optimum pH and sorption capacity were 5 and 0.18 mg/g at 20C, respectively. The profile of the drug uptake by the sorbent reflects good accessibility of the active sites in the imprinted polymer sorbent. The MIP-SPE was the most feasible technique for the extraction of clonazepam with a high recovery from human plasma and urine samples.

“…Several methods have been reported in the literature for the estimation of drugs of clonazepam and nitrazepam in either pharmaceutical forms or biological fluids, including HPLC [9][10][11][12][13][14][15][16], liquid and gas chromatography [17][18][19][20][21][22][23][24], clonazepam in blood using LC-MS/MS [25], chemiluminescence and electrochemiluminescence [26,27], electrical methods [28][29][30][31][32][33][34][35][36], flowinjection [37][38][39][40][41][42], colorimetric and various spectrophotometric methods [43][44][45][46][47][48][49][50][51][52][53][54][55][56]…”

Depending on the oxidative coupling reaction as a rapid and selective spectrophotometric method, reduced clonazepam and nitrazepam drugs were evaluated by using potassium bromate as oxidation agent for these drugs and phenylephrine hydrochloride as a new chromogenic reagent to give red coloured products for clonazepam and nitrazepam at a maximum absorption of 491 and 488 nm, respectively. The linear ranges was 2-60 µg mL -1 and 5-90 µg mL -1 while the molar absorptivity are 3.157 × 10 3 L mol -1 cm -1 and 3.825 × 10 3 L mol -1 cm -1 and their detection limits are 0.141 µg mL -1 and 0.104 µg mL -1 , respectively for clonazepam and nitrazepam. The proposed methods did not require any temperature control and also not affected by foreign excipients and henceforth successfully applied to determine clonazepam and nitrazepam in pharmaceutical preparations.
