Abstract:
IgG (immunoglobulin G) is the most abundant serum antibody found in blood circulation in humans and is not present in healthy human urine. The detection of IgG in urine is closely related to valuating the severity and predicting the trend of glomerulitis and other chronic kidney diseases. Electrochemical impedance spectroscopy (EIS) biosensors are highly sensitive and ideal for detecting IgG in urine. This technique uses micro-gap parallel plate electrode (PPE) as the electrode of the EIS biosensor and antifouling Y-shaped peptides as biometric element combined with PPE. The development of an

Abstract:
An amperometric biosensor for chlorphenvinphos (organophosphorus pesticide) based on carbon nanotube paste and acetylcholinesterase enzyme (CNTs-AChE biosensor) is described herein. This CNTs-AChE biosensor was characterized by scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). The SEM result shows the presence of CNTs and small lumps, due to the enzyme AChE, which has a type of cauliflower formation. From EIS analysis is possible to observe increasedRtcfor CNTs-AChE biosensor when compared to the carbon nanotube paste electrode for the reaction [Fe(CN)6]4−/3−

Abstract:
The sensitive determination of folate receptors (FRs) in the early stages of cancer is of great significance for controlling the progression of cancerous cells. Many folic acid (FA)-based electrochemical biosensors have been utilized to detect FRs with promising performances, but most were complicated, non-reproducible, non-biocompatible, and time and cost consuming. Here, we developed an environmentally friendly and sensitive biosensor for FR detection. We proposed an electrochemical impedimetric biosensor formed by nanofibers (NFs) of bio-copolymers prepared by electrospinning. The biosensor

Abstract:
The development of an electrochemical biosensor for the detection of phosphorylated-tau threonine 231 (p-tau231), a biomarker of Alzheimer’s disease (AD), has yet to be achieved. Therefore, in this study, we developed a simple, small size, cheap, and sensitive electrochemical biosensor based on an interdigitated wave-shaped electrode via an activated self-assembled monolayer to preserve a specific anti–p-tau231 antibody (IWE/SAM/EDC-NHS/anti–p-tau231). Detection of p-tau231 in human serum (HS) using the biosensor was undertaken using electrochemical impedance spectroscopy (EIS). The change in

Abstract:
Tethered bilayer lipid membranes (tBLMs) are increasingly used in biosensor applications where electrochemical impedance spectroscopy (EIS) is the method of choice for amplifying and recording the activity of membrane-damaging agents such as pore-forming toxins or disrupting peptides. While the activity of these biological agents may depend on the pH of the analytes, there is increasing evidence that the sensitivity of tethered bilayer sensors depends on the pH of the solutions. In our study, we addressed the question of what are the fundamental reasons for the variability of the EIS signal of

Abstract:
This study demonstrates the application feasibility of electrochemical impedance spectroscopy (EIS) in measuring estrogen (17β-estradiol) in gas phase. The present biosensor gives a linear response (R2=0.999) for 17β-estradiol vapor concentration from 3.7 ng/L to 3.7 × 10−4 ng/L with a limit of detection (3.7 × 10−4 ng/L). The results show that the fabricated biosensor demonstrates better detection limit of 17β-estradiol in gas phase than the previous report with GC-MS method.

Abstract:
Diclofenac, a widely used non-steroidal anti-inflammatory drug (NSAID), poses growing concerns in environmental contexts due to its potential toxicity and persistence. Accurate, real-time monitoring of diclofenac levels in both biological samples and water sources is essential to ensure therapeutic safety and reduce environmental impact. However, conventional methods such as high-performance liquid chromatography (HPLC) and gas chromatography (GC) are limited by their complexity, high cost, and lack of portability for on-site testing.

Abstract:
Label free detection methods are preferred in biological sensing applications due to their convenience, low reagent usage, and minimal equipment dependence. EIS (Electrolyte-Insulator-Semiconductor) is a type of biosensor that achieves this through the sensing of the intrinsic charges present within a biological entity such as a cell or DNA. The charge generates a field which modulates the width of the depletion region within the semiconductor and can be detected using capacitance measurements.
