Due to their visual interpretability and ease of use, a large number of paper-based sensors have been created as competitors to traditional detection methods. In particular, the application of nanomaterials with different strategies to paper-based biosensors can provide an enhanced colorimetric readout for selective and sensitive detection. Among them, the numerous hydroxyl groups on IrO₂ nanoparticles (IrO₂NPs) surface made it easier for organic molecules to be adsorbed, leading to optical change of IrO₂NPs in the presence of biologically important molecules as analyte. In this study, a paper-based optical sensor platform was obtained using bacterial cellulose (BC) doped with IrO₂NPs. The IrO₂NPs-doped BC (IrO₂NPs@BC) was cut into circular pieces (spot) for easily handling and used for dopamine detection.

A key factor in effective drug use is taking it at the correct dosage and timing. Otherwise, some adverse or side effects of these drugs may occur.

The simple definition of a drug (medication) is a chemical substance that produces a biological effect when adapted to an organism. There are many techniques to determine the drug amount, including spectrometric, chromatographic, electrochemical, colorimetric, or immunological. These analytical techniques have been successfully used to quantify drugs. To improve the effectiveness of the detection protocols, combined systems such as spectroelectrochemistry (SEC) provide significant advantages. This well-known technique unites the principles of spectroscopy and electrochemistry by creating a synergy to provide information on redox properties, mechanisms, and molecular structures. This review highlights the transformative potential of SEC in determining drug molecules, offering a detailed exploration of its principles, methodologies, and unique advantages.

Proteinuria serves as an indicator of structural kidney damage and is increasingly recognized as a crucial marker for kidney disease and a risk factor for AKI. Free light chains (FLCs) are being investigated as potential markers for assessing the risk of kidney damage. This study aimed to validate the early detection of AKI by examining FLCs (kappa, lambda, and the kappa/lambda ratio) in serum and saliva samples. Clinical data were collected from 149 patients who underwent cardiac surgery in Baghdad, with 90 providing both saliva and serum samples for FLC evaluation. Patients were categorized based on the severity of proteinuria. Results showed that serum kappa levels were significantly elevated in patients with severe proteinuria compared to those with mild or no proteinuria. Conversely, salivary kappa levels were higher in patients with mild proteinuria than in those with severe or no proteinuria, while salivary lambda levels decreased as proteinuria severity increased. The rise in serum kappa may be attributed to immune system activation and kidney impairment. Both serum and salivary kappa demonstrated strong predictive capabilities for post-surgery AKI prognosis, outperforming lambda and the kappa/lambda ratio based on ROC analysis. The findings suggest that FLCs, particularly kappa, could be valuable in the early detection of AKI following cardiac surgery, highlighting their potential to enhance patient outcomes through proactive monitoring and intervention.</div></div>","PeriodicalId":100822,"journal":{"name":"Journal of Pharmaceutical and Biomedical Analysis Open","volume":"5 ","pages":"Article 100058"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143280733","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}

Additionally, pesticides have a lengthy half-life in the environment, which allows them to build up in species' tissues and go up the food chain, a process known as bioaccumulation and biomagnification.
