Scientific research in plasmonic metasurfaces has been widely widespread the last years, motivated by recent advances nanofabrication field and increasing demand for high throughput sensing platforms. The electronics, microfluidics, signal processing have enabled complete development of highly integrated devices with broad application potential. However, progress observed from a fabrication poi...

Abstract Intestinal diseases that have high mortality and morbidity rates bring huge encumbrance to the public medical system economy worldwide, always been focus of clinicians scientific researchers. Early diagnosis intervention are valuable in progression many intestinal diseases. Fortunately, emergence sensor materials can effectively assist clinical early health monitoring. By accurately lo...

The photoelectrochemical charge-transfer process occurring at semiconductor surfaces has important implications in the fields of solar fuels and biodetection. Usually, physical light sources located outside liquid phase, such as a simulator, light-emitting diode (LED), or laser, are used for studies. Here, we report inducing photoelectrochemistry using an electrochemical source light, that is, ...

Exponential molecular amplification such as the polymerase chain reaction is a powerful tool that allows ultrasensitive biodetection. Here, we report new exponential strategy based on photoredox autocatalysis, where eosin Y, photocatalyst, amplifies itself by activating nonfluorescent Y derivative (EYH3-) under green light. The deactivated photocatalyst stable and rapidly activated low-intensit...

In recent years, metaplasmonic biosensors have emerged as a novel counterpart of well-established plasmonic based on thin metallic layers. Metaplasmonic offer high potential for sensor miniaturization, extreme sensitivity biosensing, and multiplexing capabilities with detection methods free coupling optical elements. These make highly attractive Point-of-Care handled/portable devices or On-Chip...
