Additive manufacturing (AM)/3D printing technology provides a novel platform for the rapid prototyping of low cost 3D platforms. Herein, we report first time, fabrication, characterisation (physicochemical and electrochemical) application (electrochemical sensing) bespoke nanographite (NG)-loaded (25 wt%) AM printable (via fused deposition modelling) NG/PLA filaments. We have optimised tailored variety NG-loaded filaments their counterparts in order to achieve optimal printability...
Nifuroxazide (NFX) is an antimicrobial agent that frequently used as intestinal antiseptic and recently was proven to have anticancer properties. This work employs the use of nitrogen sulphur co-doped carbon quantum dots (NSC-dots) luminescent nanoparticles propose a highly sensitive, sustainable, white green spectrofluorometric method for NFX detection in bulk pharmaceutical dosage forms. l-Cysteine citric acid were precursors synthesize water soluble NSC-dots by quick...
The constant and persistent synthesis abuse of new psychoactive substances have sparked the requirement for rapid, on-site, sensitive analytical protocols their sensing quantification. Mephedrone (4-MMC) is currently one most popular legal highs among recreational drug abusers imposes a serious public health problem. In this paper, electrochemical two metabolites 4-MMC, namely, nor-mephedrone (4-methylcathinone, 4-MC) dihydromephedrone (4-methylephedrine, 4-MMC-R), utilizing screen-printed...
We report a combination of HPLC and electrochemistry towards the detection heroin, fentanyl ten fentalogues.
Abstract Nitazoxanide (NTX) is an antimicrobial drug that was used for the treatment of various protozoa. However, during coronavirus pandemic, NTX has been redirected such virus primarily infect respiratory tract system. now as a broad-spectrum antiviral agent. In this study, highly sensitive and green spectrofluorometric method developed to detect in dosage forms its metabolite, tizoxanide (TX), human plasma samples using nitrogen sulfur co-doped carbon quantum dots nanosensors (C-dots). A...
Herein, a novel spectrofluorometric sensor is proposed for the sensitive analysis of two nonfluorescent mucolytic drugs, namely, acetylcysteine (ACT) and carbocisteine (CST), utilizing newly synthesized 2-[(2-hydroxyethyl)-(2,8,10-trimethylpyrido[2',3':3,4]pyrazolo[1,5-a]pyrimidin-4-yl)-amino]-ethanol as fluorescence probe (Flu. Probe). This fluorophore exhibits emission at 445 nm upon excitation 275 nm. The addition increasing concentrations each drug resulted in quantitative quenching Flu....
Abstract This paper shows the development of an electrochemical sensor for sensitive estimation cariprazine (CRZ), FDA-approved drug to treat schizophrenia and acute manic. Voltammetric studies were developed utilizing a carbon paste electrode (CPE) modified with novel nanohybrid material composed silver zinc oxide nanoparticles (Ag/ZnO NPs) Prussian blue analogue (PBA, ZnTCNi/HCCo) that was prepared through chemical co-precipitation technique. Its structural, compositional, morphological...
One of the most significant advancements in rapidly expanding field nanotechnology is colloidal semiconductor nanocrystals, often known as quantum dots. Originally suggested fluorescent biological markers, they are now discovering new applications analytical chemistry owing to their promising optical, structural, and electrical properties. Carbon dots have attracted a lot attention lately because sustainability, strong biocompatibility, water solubility, low cost manufacture, superior...

Simple, sensitive and specific spectrophotometric (Method I) spectrofluorimetric II) methods were developed for the determination of three sulfur-containing drugs: mesna (MSN), acetylcysteine (ACT) timonacic acid (TMN).
We report the electroanalytical properties of graphene and graphite paste electrodes comprising varying lateral flake sizes when applied for sensing relevant biomolecules prominent drugs abuse.
The emergence of a new class novel psychoactive substances, N-benzyl-substituted phenethylamine derivatives so-called "NBOMes" or "Smiles", in the recreational drug market has forced development sensitive analytical methodologies for their detection and quantitation. NBOMes' hallucinogenic effects mimic those illegal psychedelic lysergic acid diethylamide (LSD) are typically sold as LSD on blotter papers, resulting remarkable number fatalities worldwide. In this article, four halide NBOMe,...
Four simple and sensitive spectrophotometric methods were developed for the determination of sulfhydryl containing drug mesna (MSN). Methods I II rely on nucleophilic aromatic substitution reactions using two UV tagging reagents namely: 4-chloro-7-nitrobenzo-2-oxa-1,3-diazole (NBD-Cl) method 2,4-dinitrofluorobenzene (DNFB) II. Both took place in alkaline buffered medium obtained yellowish products measured at 414 332 nm II, respectively. III IV are indirect based suppressive effect MSN...
