Article Abstract
Bisphenol A (BPA) is an endocrine disrupting chemical and broadly used in plastics. The leakage of BPA in food and water cycles poses a significant risk to the environment and human health. Thus, monitoring the concentration of BPA to avoid its potential risk is highly important. In this work, a simple and efficient oxygen deficient molecularly imprinted TiO electrochemical sensor was proposed for the detection of BPA. The introduction both oxygen vacancies and molecular imprinting evidently enhanced the electrochemical oxidation signal of BPA. The sensor had a good linear response ranging from 0.01 μM to 20 μM with a limit of detection of 3.6 nM. Additionally, the sensor showed remarkable stability, reproducibility and interference resistant ability. It also exhibits excellent recovery during the detection of real water. These findings suggested that the sensor has the potential to be developed as a simple, efficient and low-cost monitoring system for the monitoring of BPA in water.

A novel molecularly imprinted polymer (MIP)-based electrochemical sensor has been developed for the selective detection of naringenin (NAR) in various real-world samples, including plant extracts, wine, and herbal supplements. To enhance the active surface area and porosity of the glassy carbon electrode (GCE), a 2D/0D nanocomposite composed of graphene oxide (GO) and cobalt ferrite (CFO) nanoparticles, CFO_GO, was incorporated into the sensor design. 4-aminobenzoic acid (4-ABA) was selected as the functional monomer to prepare the MIPs.

Electrochemical sensors capable of detecting different types of biomolecules using a single electrode are highly desirable for simplifying analytical platforms and expanding their practical applicability. Herein, we develop a multifunctional electrochemical sensor based on a 3D honeycomb-like porous rGO/PPy-POM composite film for the independent detection of dopamine (DA) and folic acid (FA), two chemically distinct and clinically relevant biomolecules. The electrode is fabricated through a facile, low-cost, and environmentally friendly breath figure method to create a 3D porous reduced graphene oxide (rGO) framework, followed by codeposition of polypyrrole (PPy) and polyoxometalates (POMs).

High-fat foods are decomposed into fatty acids during digestion and absorption, primarily occurring in the gastrointestinal tract, and numerous studies have indicated that long-term high-fat diets significantly increase the incidence of intestinal disorders. As a critical intestinal hormone, serotonin (5-hydroxytryptamine, 5-HT) is involved in regulating intestinal peristalsis, secretion, and visceral sensitivity. However, due to the lack of methods capable of reproducing intestinal mechanical activities and in situ monitoring of 5-HT levels, the influence of high-fat diets on intestinal 5-HT release remains unclear.

The study addresses the critical issue of sepsis diagnosis, a life-threatening condition triggered by the body's immune response to infection that leads to mortality. Current diagnostic methods rely on the time-consuming assessment of multiple biomarkers by a series of tests, leading to delayed treatment. Here, we report a platform for developing a point-of-care (POC) device utilizing electrochemical immunosensors for the dual and rapid detection of sepsis biomarkers: Procalcitonin (PCT), Interleukin-6 (IL-6), and C-reactive protein (CRP) as host markers and lipopolysaccharide (LPS) as a pathogen marker.
