Aluminum-Doped Zinc Oxide Enzymatic Dopamine Biosensor Integrated With Potentiometric Readout Circuit Board

Po-Hui Yang et al.

Summary: In this study, a standard industrial flexible printed circuit board (FPCB) was used to fabricate a potentiometric enzymatic dopamine (DA) biosensor. The sensing films of the DA sensor were made from aluminum-doped zinc oxide (AZO) using a radio frequency (RF) sputtering system. Tyrosinase (Tyr) was immobilized on the AZO film using (3-Aminopropyl)triethoxysilane (APTES) and glutaraldehyde. The DA sensor showed good sensing characteristics, including selectivity for DA in the presence of other interfered biomolecules.

Boric acid-functionalized silver nanoparticles as SERS substrate for sensitive and rapid detection of fructose in artificial urine

Jialu Shen et al.

Summary: The detection of fructose in human urine using surface-enhanced Raman spectroscopy (SERS) has significant implications in preventing and screening diseases such as fructokinase deficiency and hereditary fructose intolerance. The boronic acid-functionalized SERS substrate achieved a high sensitivity with a detection limit of 0.084 mu mol/L in water and 0.535 mu mol/L in urine, making it a reliable method for fructose detection in bioassay and clinical medicine.

ZnO and AZO Film Potentiometric pH Sensors Based on Flexible Printed Circuit Board

Po-Hui Yang et al.

Summary: In this study, zinc oxide (ZnO) and aluminum-doped zinc oxide (AZO) were deposited on the electroless nickel immersion gold (ENIG) surface of a flexible printed circuit board (FPCB) to fabricate a potentiometric pH sensor. The characteristics of the pH sensor, including average sensitivity and linearity, drift effect, and repeatability, were observed through voltage-time (V-T) measurements in pH 2 to 10 buffer solutions. The experimental results demonstrated the good characteristics of the pH sensors in this study.

Differential pulse voltammetry and chronoamperometry as analytical tools for epinephrine detection using a tyrosinase-based electrochemical biosensor

Sylwia Baluta et al.

Summary: The study aims to develop a biosensor-based system for detecting epinephrine using a poly-thiophene derivative and tyrosinase as the recognition element. Comparison of two electroanalytical techniques showed that differential pulse voltammetry (DPV) exhibited a wider linear range and lower detection limit compared to chronoamperometry (CA). The prepared biosensor system demonstrated good parameters and high selectivity for epinephrine detection, making it suitable for pharmaceutical applications.
