Inspired by the rapid progress and existing limitations in surface plasmon resonance (SPR)
biosensing technology, we have summarized the recent trends in the fields of both chip-SPR …

The design and application of sensors for monitoring biomolecules in clinical samples is a
common goal of the sensing research community. Surface plasmon resonance (SPR) and …

Antibodies or immunoglobulins (Ig) are proteins produced by the immune system to protect
the body by identifying and neutralizing pathogens. The determination of antibodies is an …

We report a surface plasmon resonance (SPR) sensor detecting nucleocapsid antibodies
specific against the novel coronavirus 2019 (SARS-CoV-2) in undiluted human serum …

Aluminum has recently attracted considerable interest as a plasmonic material due to its
unique optical properties, but most work has been limited to nanostructures. We report here …

This paper presents the first label-free and sensitive electrochemical immunosensor for
efficient and rapid detection of Citrus tristeza virus (CTV). The specific antibody against coat …

Diagnosing chronic Chagas disease (CD) requires antibody–antigen detection methods,
which are traditionally based on enzymatic assay techniques whose performance depend …

Polypyrrole (Ppy) is a biologically compatible polymer that is used as a matrix, in which
drugs and enzymes can be incorporated by doping. Here, we suggest an inventive …
