Heavy metal pollution has become more and more serious with industrial development and
resource exploitation. Because heavy metal ions are difficult to be biodegraded, they …

Heavy metals (HMs) and rare earth elements (REEs) are used in a wide range of industrial
and technological applications, but they can also have harmful effects on the environment …

Realizing high‐precise and adjustable regulation of engineering nanozyme is important in
nanotechnology. Here, Ag@ Pt nanozymes with excellent peroxidase‐like and antibacterial …

Heavy metals accumulating in the human body produce physiological toxicity by interfering
with the transport of human proteins and enzymes. Heavy metals detection is significant for …

Abstract ssDNA aptamers have been increasingly used to detect heavy metal ions as

Biosensors are analytical tools with a great application in healthcare, food quality control,
and environmental monitoring. They are of considerable interest to be designed by using …

The ultimate sensitivity of field-effect-transistor (FET)-based devices for ionic species
detection is of great interest, given that such devices are capable of monitoring single …

Lead contamination is a major concern in food safety and, as such, many lead detection
methods have been developed, especially aptamer-based biosensors. However, the …

Various biosensors based on aptamers are currently the most popular rapid detection
approaches, but the performance of these sensors is closely related to the affinity of …

Abstract Lead ion (Pb 2+) is a main heavy metal in food that causes heavy teratogenicity and
carcinogenicity. In this study, a rapid and sensitive SERS method for detecting Pb 2+ in food …
