Biosensors could register a biological event and convert it into a measurable signal with
specific biosensing elements and transducers. 1− 5 A DNA biosensor is a device that …

Quantum-dot-based photoelectrochemical sensors are powerful alternatives for the
detection of chemicals and biochemical molecules compared to other sensor types, which is …

In this study, a facile hydrothermal process was used to prepare the NSs of ZnO/Yb2O3 in an
alkaline medium (pH∼ 10.5), at a low temperature. The calcined NSs were characterized by …

In this work, low-toxicity fluorescent gold nanoclusters (AuNCs) based photoelectrochemical

Among the currently multitudinous analytical methods for hydrogen peroxide (H 2 O 2),
photoelectrochemical (PEC) sensors stand out for their potential advantages of high …

Abstract Hydrogen peroxide (H 2 O 2) is a major transmitter of redox signals during chemical
processes. Cost-effective and easy-to-operate sensors for H 2 O 2 are in high demand in a …

An ultrasensitive and selective photoelectrochemical (PEC) aptasensor for mercury ions was
first fabricated based on perylene-3, 4, 9, 10-tetracarboxylic acid/graphene oxide (PTCA/GO) …

The rapid and sensitive detection of H2O2 is of great importance for a series of industries. In
this work, surface-modified FePt nanoparticles were loaded into metal–organic frameworks …
