Aptamers, a group of nucleic acids which can specifically bind to a target molecule, have
drawn extensive interest over the past few decades. For analytics, aptamers represent a …

The stressful conditions of today-life make it urgent the timely prevention and treatment of
many physiological and psychological disorders related to stress. According to the …

We demonstrate a composite nanomaterial, termed an aptamer nano-flare, that can directly
quantify an intracellular analyte in a living cell. Aptamer nano-flares consist of a gold …

Adenosine triphosphate (ATP) is the most direct source of energy in organisms. This study is
the first to demonstrate that ATP-aptamer complexes provide greater protection for …

This review (with 340 refs) focuses on methods for specific and sensitive detection of
metabolites for diagnostic purposes, with particular emphasis on electrochemical …

Aptamers, which are artificial oligonucleotides selected in vitro, have been employed to
design novel biosensors (ie, aptasensors). In this work, we first constructed a label-free …

The detection of Escherichia coli (E. coli) is crucial for water monitoring, environmental
evaluation, and food safety. E. coli is a versatile bacterium with significant implications for …

Molecular biorecognition processes facilitate physical and biochemical interactions between
molecules in all crucial metabolic pathways. Perhaps the target analyte and the …

This paper reviews the advancements of a wide range of electrochemical aptamer‐based
biosensors, electrochemical aptasensors, for target analytes monitoring. Methods for …

Aptamers are short single-stranded DNA or RNA, which can be selected from random
combinatorial library by SELEX in vitro. The SELEX technology has been modified over the …
