“…Lastly, ds-DNA was added via immobilization through holding an electrochemical potential of +0.5 V (vs. Ag/AgCl) for 270 s. This nanocomposite was evaluated to addition of 5-ASA over the range of 0.03−100 μM with a LoD of 9 nM. 60 The author explored the selectivity of the sensor through exploring 100-fold concentration of glucose, norepinephrine, ascorbic acid, citrate, folic acid, and 200-fold concentration of calcium, sodium, and chloride which showed no effect. The analytical determination of 5-ASA was evaluated within spiked human urine and serum and a pharmaceutical tablet where they observed recoveries from 97% to 104%, while the authors note that they need to undertake future work exploring this with LC-MS.…”

Mesalamine, known as 5-aminosalicylic acid, is a medication used primarily in the treatment of inflammatory bowel disease, including ulcerative colitis and Crohn's disease. 5-Aminosalicylic acid can be measured using various benchtop laboratory techniques which involve liquid chromatography−mass spectroscopy, but these are sophisticated and large, meaning that they cannot be used on-site because transportation of the samples, chemicals, and physical and biological reactions can potentially occur, which can affect the sample's composition and potentially result in inaccurate results. An alternative approach is the use of electrochemical based sensing platforms which has the advantages of portability, cost-efficiency, facile miniaturization, and rapid analysis while nonetheless providing sensitivity and selectivity. We provide an overview of the use of the electroanalytical techniques for the sensing of 5-aminosalicylic acid and compare them to other laboratory-based measurements. The applications, challenges faced, and future opportunities for electroanalytical based sensing platforms are presented in this review.

Composites comprising conductive polymers and metal particles have garnered considerable interest in sensor technology due to their excellent electrical conductivity. However, producing controllable pressure sensors that retain high sensitivity under microstress remains challenging. Polyimide (PI) sponge exhibits excellent chemical and thermal stability and a porous structure that facilitates considerable deformation under low stress levels and results in good sensitivity to external forces. Herein, a conductive polymer–metal composite conductive phase, polypyrrole–silver (PPy–Ag), is directly fabricated on the PI surface through incipient network conformal growth. This method ensures that the PPy–Ag composite maintains optimal performance within its original temperature range, thereby enhancing detection sensitivity at low stress levels. The maximum conductivity of the fabricated PPy–Ag/PI composite sponge‐based flexible piezoresistive sensor is 2.42 × 10−4 S m−1, and the sensitivity is recorded at 16.31 kPa−1 within a stress range of 0–80 Pa. After undergoing 1000 compression cycles, the sensor exhibits commendable stability and reproducibility.
