Detecting lower levels of IBR in humans could significantly contribute to different areas of research, such as drug delivery. In this work, an electrochemical sensor was designed using a molecularly imprinted polymer on a glassy carbon electrode (GCE) for the selective and sensitive determination of IBR. A polymeric film was obtained on the GCE surface by photopolymerization (PP) method using template molecule IBR, 2-hydroxyethyl methacrylate (HEMA), ethylene glycol dimethacrylate (EGDMA), and 4-aminobenzoic acid (4-ABA). Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and scanning electron microscopy (SEM) were used to examine the sensor's morphological and electrochemical characteristics. In addition, the parameters affecting the MIP were optimized. For the first time, a MIP-based electrochemical sensor was designed to determine IBR. Low limit of detection (LOD) and limit of quantification (LOQ) values of 6.13 × 10<sup>−14</sup> and 2.04 × 10<sup>−13</sup> M were obtained, respectively. The developed sensor detected IBR at least 3 times more selectively than similar substances (pemetrexed (PEM), tofacitinib (TOF), and ruxolitinib (RUX)). IBR detection was investigated in biological samples and pharmaceutical dosage forms. Furthermore, the sensor successfully distinguished IBR from compounds with similar structures, demonstrating great selectivity.</div></div>","PeriodicalId":100822,"journal":{"name":"Journal of Pharmaceutical and Biomedical Analysis Open","volume":"5 ","pages":"Article 100055"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Belgium, the transposition of this directive requires that nicotine-containing e-liquid boosters cannot exceed a concentration of 20 mg mL<sup>−1</sup> to ensure consumers safety. Nowadays, accurate analytical methods available to measure nicotine levels in e-liquid products involve chromatography. The development of alternative analytical tools being faster, greener and adaptable to in-field analyses are therefore required. Surface-enhanced Raman scattering is a spectroscopic technique that significantly enhances inherent Raman scattering signals, improving detection limits, when analytes are adsorbed onto metallic nanostructures such as gold nanoparticles (AuNPs). This study introduces new SERS methods for quantifying nicotine in e-liquid boosters using two different Raman spectrophotometers based on a transmission (SETRS) and a backscattering detection mode. The transmission Raman spectrophotometer has a better sample representativity, which is very interesting to perform SERS on liquids samples, and an autosampler offering facilities for routine analyses as a benchtop equipment while the second spectrophotometer was a handheld Raman device allowing to expand the use of the developed SERS method to in-field analyses. These SERS analyses were performed using lab-synthetized AuNps and by adding an isotope-edited internal standards (IEISs) being nicotine-d4 to mitigate some repeatability issues. These methods were finally validated according to the ICH Q2 (R2) guidelines for a working range from 100 to 300 µg L<sup>−1</sup> of nicotine concentrations using a total error risk-based approach considering the acceptance limits fixed at 15 % and a risk level of 5 %.</div></div>","PeriodicalId":100822,"journal":{"name":"Journal of Pharmaceutical and Biomedical Analysis Open","volume":"5 ","pages":"Article 100054"},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tomato PDNVs have anti-inflammatory activity <em>in vitro</em> which could be further increased by the loading of a lipophilic natural compound, like curcumin. Recently, tolvaptan, a synthetic selective vasopressin V2-receptor antagonist drug was also successfully loaded into tomato PDNVs. In this work, we have advanced the analysis of native and loaded PDNVs and compared them with liposomes using nanoplasmonic sensing (NPS).

In addition to NPS, micro differential scanning calorimetry was used to get a deeper understanding of the interactions between tolvaptan and the various liposome compositions. The result of the comparative NPS study showed that tolvaptan can be successfully incorporated both into PDNVs and liposomes of different compositions. The PDNV/tolvaptan and liposome/tolvaptan systems were found to be stable.
