A novel self-powered and flexible enzymatic biofuel cell (EBFC)-based aptasensor was developed for the sensitive and selective detection of 17 β-estradiol (E2). A flexible polyvinyl alcohol (PVA)-tannic acid‑carbon nanotube/reduced graphene oxide (PTCR) substrate was modified with gold nanoparticles (AuNPs) and thiolated aptamer 1 (Apt1) to yield Apt1@AuNPs/PTCR. A copper-based metal-organic framework (Cu-MOF) with peroxidase mimicking activity was employed to anchor glucose oxidase (GOD) and Apt2, forming the Cu-MOF@GOD/Apt2 tag.

- A new perovskite-based photoelectrochemical (PEC) platform has been created to measure alkaline phosphatase (ALP) activity in milk and serum samples.
- The platform works by detecting ascorbic acid (AA) produced when ALP in the sample hydrolyzes a specific substrate, which is then monitored using a specialized cathode.
- This method shows high sensitivity and selectivity for ALP detection, with a low limit of detection and a wide range for measurement, making it promising for food and biomedical applications.
A flexible electrochemical sensor based on the carbon felt (CF) functionalized with Bisphenol A (BPA) synthetic receptors was developed. The artificial Bisphenol A receptors were grafted on the CF by a simple thermal polymerization molecular imprinting process. Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and electrochemical characterizations were used to analyze the receptors.
