A Direct Z-Scheme AgBr/CuBi2O4 Photocathode for Ultrasensitive Detection of Ciprofloxacin and Ofloxacin by Controlling the Release of Luminol in Self-Powered Microfluidic Photoelectrochemical Aptasensors

“…1 Thus, the sensors exhibited a wide dynamic range and outstanding sensitivity in the field of biological assays, 4 pesticide residues detection, 5 and food analysis. 6 Even though the performance of the PEC sensor has reached a satisfactory level, multitarget quantitative analysis remains a challenge. Besides, one of the most pressing tasks is to develop a portable and miniaturized PEC detection platform for ultrasensitive analysis.…”

“…Self-powered photoelectrochemical (PEC) sensors that can convert optical signals into electrical signals without an external voltage have attracted extensive attention. − Furthermore, the self-powered PEC sensors that integrate photoanode and photocathode, rather than redundant three-electrode systems, have a simplified structure . Thus, the sensors exhibited a wide dynamic range and outstanding sensitivity in the field of biological assays, pesticide residues detection, and food analysis . Even though the performance of the PEC sensor has reached a satisfactory level, multitarget quantitative analysis remains a challenge.…”

“…In recent years, fluoroquinolone antibiotics (FAs) have been widely used in healthcare and veterinary medicine to treat bacterial infections. , FAs, in particular, exhibited extraordinary efficacy against a wide range of Gram-positive and Gram-negative pathogenic bacteria. , However, residues of FAs have emerged as potential contaminants due to their excessive production and unsafe disposal. And the presence of antibiotics in animals and surface water may badly endanger human health via the food chain .…”

Catalytic Decomposition of the Hole-Derived H2O2 by AgBiS2@Ag Nanozyme to Enhance the Photocurrent of Z-Scheme BiVO4/ZnIn2S4 Photoelectrode in Microfluidic Immunosensing Platform

“…The photoelectrochemical (PEC) sensor, which possesses alluring advantages of low background noise, rapid responses, and high sensitivity, has attracted continuously growing scientific interest in the field of bioanalysis, food analysis, and environmental pollutant monitoring. − Nevertheless, the lack of miniaturization and portability extremely limits its application in actual sample testing. , In addition, ultrasensitive and efficient biomarker analysis has great significance for early diagnoses and treatment of disease . Therefore, in this paper, an innovative analytical platform was successfully established, which integrated a microfluidic chip possessing superiorities of less sample consumption, easy integration, and miniaturization with a PEC sensor, and could achieve accurate detection of cytokeratin 19 fragments (CYFRA21–1).…”

High-Throughput Detection of Multiple Contaminants Based on Portable Photoelectrochromic Sensor Chip

“…In recent years, photoelectrochemical (PEC) biosensors have attracted more and more attentions. Under light illumination, electric signals, such as photocurrent or photovoltage, are affected by the interactions between the analyte and PEC active materials. − Quantification is achieved based on this PEC response change. Due to the separation of the excitation source and the detection signal, PEC sensing has a low background noise, which ensures good sensitivity. , However, this technology also has certain drawbacks.…”
