Nucleic acid aptamers are oligonucleotide sequences screened by an in vitro methodology
called Systematic Evolution of Ligands by Exponential Enrichment (SELEX). Known as …

Background Nucleic acid aptamers, defined as small functional nucleic acids that can
selectively bind to a specific target, have become one of the main bio-recognition elements …

We performed in vitro selection experiments to identify DNA aptamers for the S1 subunit of
the SARS-CoV-2 spike protein (S1 protein). Using a pool of pre-structured random DNA …

Conspectus Pathogens have long presented a significant threat to human lives, and hence
the rapid detection of infectious pathogens is vital for improving human health. Current …

Abstract An Au‐on‐Au tip sensor is developed for the detection of Salmonella typhimurium
(Salmonella), using a new synthetic nucleic acid probe (NAP) as a linker for the …

In recent years, foodborne pathogenic bacteria have gained increasingly serious public
concerns. Therefore, the construction of simple, rapid, effective, and low-cost methods for …

Chemical and biological contaminants are of primary concern in ensuring seafood safety.
Rapid detection of such contaminants is needed to keep us safe from being affected. For …

Since the systematic evolution of ligands by exponential enrichment (SELEX), a process that
has been used extensively in many studies, has yielded mixed results, researchers are …

Functional nucleic acids (FNAs) are short, single-stranded nucleic acids that can be derived
from synthetic nucleic acid libraries using test-tube selection experiments. Due to their …

The detection of pathogens is critical for preventing and controlling health hazards across
clinical, environmental, and food safety sectors. Functional nucleic acids (FNAs), such as …
