Universal sulfatase-based chemiluminescence biosensing platform: Validation via AFP detection in clinical blood samples
Enzyme-catalyzed chemiluminescence has been widely used in the field of biomedicine, especially in the test kit for various biomarkers. However, the currently reported enzyme-catalyzed chemiluminescence systems suffered from the addition of oxidizing substances, short emission wavelength, and susceptibility to interference by autofluorescence. In this paper, a universal sulfatase-based chemiluminescence system with NIR was developed, in which the designed substrate QM-CF could be transformed into 1,2-dioxetane derivate in the presence of sulfatase and oxygen. This system exhibited long emission wavelengths and CL half-time, a high signal-noise ratio, and without other additives. Importantly, the sulfatase-based chemiluminescence enzyme-linked immunoassay platform was successfully constructed and could be generally applied to detect biomarkers. As a proof of concept, the sulfatase-labeled AFP antibody and substate QM-CF were conveniently suitable for commercial AFP test kits, leading to satisfactory detection results of AFP in clinical blood samples.
期刊介绍：
Biosensors & Bioelectronics, along with its open access companion journal Biosensors & Bioelectronics: X, is the leading international publication in the field of biosensors and bioelectronics. It covers research, design, development, and application of biosensors, which are analytical devices incorporating biological materials with physicochemical transducers. These devices, including sensors, DNA chips, electronic noses, and lab-on-a-chip, produce digital signals proportional to specific analytes. Examples include immunosensors and enzyme-based biosensors, applied in various fields such as medicine, environmental monitoring, and food industry. The journal also focuses on molecular and supramolecular structures for enhancing device performance.
