Gold nanoparticles (AuNPs) are extremely promising objects for solving a wide range of
biomedical problems. The gold nanoparticles production by biological method (“green …

Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

We review the progress achieved during the recent five years in immunochemical
biosensors (immunosensors) combined with nanoparticles for enhanced sensitivity. The …

The main challenge for all electrical, mechanical and optical sensors is to detect low
molecular weight (less than 400 Da) chemical and biological analytes under extremely …

Anisotropic gold nanoparticles (AuNPs) have attracted the interest of scientists for over a
century, but research in this field has considerably accelerated since 2000 with the synthesis …

Aptamers are single-stranded nucleic acids that selectively bind to target molecules. Most
aptamers are obtained through a combinatorial biology technique called SELEX. Since …

Graphene–gold metasurface architectures that can provide significant gains in plasmonic
detection sensitivity for trace-amount target analytes are reported. Benefiting from extreme …

A biosensor is a device that reacts with the analyte to be analyzed, detects its concentration,
and generates readable information, which plays an important role in medical diagnosis …

We have synthesized silver nanoparticles from silver nitrate solutions using extracts of
Rumex hymenosepalus, a plant widely found in a large region in North America, as reducing …

Nucleic acid aptamers are promising alternatives to antibodies in analytics. They are
generally obtained through an iterative SELEX protocol that enriches a population of …
