Dibenzo-18-crown-6-based carbon paste sensors for the nanomolar potentiometric determination of daclatasvir dihydrochloride: An anti-HCV drug and a potential candidate for treatment of SARS-CoV-2

Smartphone-Assisted EY@MOF-5-Based Dual-Emission Fluorescent Sensor for Rapid On-Site Detection of Daclatasvir and Nitenpyram

“…In addition, approaches for efficient DCT detection in biological media would save patient care time and cost. 10 Similarly, extensive pesticide applications in agriculture have created severe environmental concerns since they easily diffuse into water, air, food, and soil, causing threats to fauna and flora. 11 Pesticides are not degraded easily and have approximately 10−30 years of half-life.…”

“…Therefore, developing a selective and rapid method can benefit physicians’ effective drug dosage monitoring and minimizing its adverse effects and interactions. In addition, approaches for efficient DCT detection in biological media would save patient care time and cost …”

Ionophore-Based Nanosphere Emulsion Incorporating Ion-Exchanger for Picogram Potentiometric Determination of HCV Drug (Daclatasvir) in Pharmaceutical Formulations and Body Fluids

“…Potentiometric and pH measurements were performed with the Jenway pH-mV Model 3510 (UK), using a Metrohm Ag-AgCl as a reference electrode. A DAC-selective carbon paste electrode served as a working electrode, and it was prepared as described elsewhere [21] with a (w/w)% composition of 69.38%:29.38%:1%:0.25% of graphite:DOP: DB18C6:Na-TimB. High-resolution transmission electron microscopy was performed at HR-TEM (JEOL, JEM -2100, Tokyo, Japan).…”

“…Subsequently, increasing volumes of DAC (analyte) were added to the cell, and the cell potential was continuously monitored (Figure 3A). To detect the endpoint, a DAC-selective ISE was utilized as a working (indicator) electrode [21]. Before the endpoint, the nanospheres imposed a very low concentration of DAC 2+ ions in the aqueous solution because it was exchanged with Na + and entered the nanosphere's core.…”

Molecularly-imprinted polymer-base bulk optode for the determination of ivabradine hydrochloride in Procoralan®

“…4. 11,28 To conrm the selectivity shown by SSM, measurements were performed by MSM reported by Wang and Meyerhoff; 24 selectivity pattern of miptode 2 and niptode 3 were comparable for ionic species by applying the MSM as shown in Fig. 6.…”
