The cocaine aptamer was later found to bind quinine with an even higher affinity. In this
work, we used a fluorescently labeled aptamer named MN4 to study its adsorption by gold …

Target-directed aptamer adsorption by gold nanoparticles (AuNPs) has been widely used to
develop label-free colorimetric biosensors. However, the potential interactions between …

DNA aptamers that bind biomolecular targets are of interest as the recognition element in
colorimetric sensors based on gold nanoparticles (AuNP), where sensor functionality is …

Cocaine is one of the most commonly misused stimulant which could influence the central
nervous system. In this study, a fluorescent aptamer-based sensor (aptasensor) was …

In this study, a thiol-modified aptamer was immobilized on a gold nanoparticle-modified
molybdenum disulfide composite material (MoS2@ AuNPs), which could remove the …

Herein, a novel colorimetric aptasensor was introduced for detection of cocaine based on
the formation of three-way junction pockets on the surfaces of gold nanoparticles (AuNPs) …

Summary of main observation and conclusion Aptamer serves as a potential candidate for
the micro‐detection of cocaine due to its high specificity, high affinity and good stability …

In this paper, a simple, highly sensitive, and cost-effective method was described for cocaine
detection as an example in the stimulants using an aptamer-functionalised gold …

A novel chemiluminescence (CL) aptasensor for highly sensitive detection of small-molecule
targets using cocaine as a model analyte was developed in the present study. For the …

A simple, sensitive and selective colorimetric biosensor for the detection of dopamine (DA)
was demonstrated with a 58-mer dopamine-binding aptamer (DBA) as recognition element …
