Article Synopsis
- - A new, affordable potentiometric sensor for detecting erythromycin (ERY) uses circular carbon dots and incorporates nanomaterials (f-MWCNTs/PANi) to improve performance, offering high sensitivity and selectivity against other similar drugs.
- - The sensor operates with a detection limit of 9.6 ± 0.4 × 10 M and shows excellent selectivity when tested against related substances like azithromycin and paracetamol, making it suitable for accurate drug monitoring.
- - Validated for use in pharmaceutical formulations and human urine samples, the sensor demonstrates recovery rates between 93.0% and 104.3%, showcasing its effectiveness even in complex biological matrices with minimal sample volume needed.
Article Synopsis
- - Myoglobin (Mb) is a key cardiac biomarker for quickly diagnosing cardiovascular issues, prompting the development of a reliable and affordable paper-based sensing device for point-of-care monitoring.
- - A custom biomimetic antibody for myoglobin was created using a molecular imprinting technique on carboxylated multiwalled carbon nanotubes, and the sensor's effectiveness was validated through various analyses.
- - The sensor demonstrated strong selectivity for myoglobin, a detection limit of 28 nM, and successful recovery in fake serum samples, suggesting it could serve as a scalable and cost-effective tool for clinical analysis.
Caffeine is a psychoactive drug that is administered as a class II psychotropic substance. It is also considered a component of analgesics and cold medicines. Excessive intake of caffeine may lead to severe health damage or drug addiction problems.

The potentiometric platforms integrate both the FLX sensor and the reference Ag/AgCl electrode. The sensors were based on the use of 4'-nitrobenzo-15-crown-5 (ionophore I), dibenzo-18-crown-6 (ionophore II), and 2-hydroxypropyl-β-cyclodextrin (2-HP-β-CD) (ionophore III) as neutral carriers within a plasticized PVC matrix.
