Rapid detection of nucleic acids (DNA or RNA) by inexpensive, selective, accurate, and
highly sensitive methods is very important for biosensors. DNA-sensors based on DNA …

Recent years have witnessed an exponential increase in the research on gold nanoparticles
(AuNPs)-based colorimetric sensors to revolutionize point-of-use sensing devices. Hence …

Electrochemical immunoassays can be developed in a way that allows them to become an
alternative to enzyme-linked immunosorbent assays as clinical diagnostic tools. In this …

The colorimetric sensors for reducing sugars based on a redox reaction between AuCl 4−
ions and fructose, glucose, lactose, or mannose are presented. Gold nanoparticles (AuNPs) …

With the increasing importance of healthcare and clinical diagnosis, as well as the growing
demand for highly sensitive analytical instruments, immunosensors have received …

In this study, a Au-Fe3O4 nanocomposite-coated carbon paste electrode was developed as
a simple, inexpensive, and efficient sensor for the removal and detection of para nitrophenol …

Phthalates, also called phthalic acid esters (PAEs), are well-known endocrine-disrupting
chemicals (EDCs) that have been detected in residential and occupational environments. In …

Bone marrow mesenchymal stem cells (BMMSCs) possess a strong ability to differentiate
into the chondrogenic lineage, which is important for cartilage regeneration. External stimuli …

We studied the direct electron transfer (DET) between glucose and electrogenerated AuCl4−
catalysed by glucose oxidase (GOx) and gold nanoparticles (AuNPs) by scanning …

Herein a uric acid (UA) biosensor based on triangular Au nanoplates–uricase was
presented. In the presence of uricase and oxygen, UA was oxidized to produce H 2 O 2. H 2 …
