Article Synopsis
- The study aimed to create a biosensor for detecting epinephrine using a poly-thiophene derivative and an enzyme called tyrosinase as the recognition element.
- The differential pulse voltammetry (DPV) technique was found to be the most effective for analysis, showing a wide linear detection range and low detection limits, while the chronoamperometry (CA) technique had less favorable performance.
- The developed biosensor demonstrated high sensitivity, stability, and selectivity, effectively distinguishing epinephrine from interfering substances and successfully analyzing a pharmaceutical sample.
The study of neurotransmitters and stress hormones allows the determination of indicators of the current stress load in the body. These species also create a proper strategy of stress protection. Nowadays, stress is a general factor that affects the population, and it may cause a wide range of serious disorders.

- The study explores how pH levels affect the optical characteristics and stability of quantum dots (QDs) by modifying hydrophobic CdSe/CdS QDs with 3-mercaptopropionic acid.
- The best functionalization efficiency (45%) and preservation of photoluminescence (PL) occurred under acidic conditions, even though the PL was significantly lower than that of hydrophobic QDs.
- The research indicates that QDs maintain strong PL at specific pH levels regardless of the initial pH during the modification process, with PL intensity behaving differently for QDs modified under various pH conditions over a broad pH range (2-12).
In this review we present polymeric materials for (bio)sensor technology development. We focused on conductive polymers (conjugated microporous polymer, polymer gels), composites, molecularly imprinted polymers and their influence on the design and fabrication of bio(sensors), which in the future could act as lab-on-a-chip (LOC) devices. LOC instruments enable us to perform a wide range of analysis away from the stationary laboratory.
