Disposable immunosensor for determination of leptin in serum and breast milk

Scientists in Spain have developed a disposable magnetic bead-based immunosensor to detect the hormone leptin. Leptin helps regulate food intake and is thought to play a role in obesity. This new sens...

AAPS PharmSciTech: PEGylated Single-Walled Carbon Nanotubes as Nanocarriers for Cyclosporin A Delivery

Type: Original PaperSingle-walled carbon nanotubes (SWCNTs) have attracted the attention of many researchers due to their remarkable physicochemical features and have been found to be a new family of...

Bedside detection of the signatures of heart disease

A disposable point-of-care device has been designed that can detect cardiac troponin I (cTnI) – a biomarker that is highly specific to cardiac injury. The approach uses a surface acoustic wave immun...

Electrochemical sensor for coeliac disease promises easy diagnosis of gluten allergy

Researchers have developed the first example of an electrochemical immunosensor for the diagnosis of coeliac disease – a genetically determined specific immune response to the antigens present in g...

Impedimetric immunosensor based on SWCNT-COOH modified gold microelectrodes for label-free detection of deep venous thrombosis biomarker.

Measurement of D-dimer has subsequently become an essential element in the diagnostics of deep vein thrombosis and pulmonary embolism; in this context microelectrodes with an area of 9x10(-4)cm(2) wer...

Labelless impedance immunosensor based on polypyrrole-pyrolecarboxylic acid copolymer for hCG detection.

In this work, a sensitive label-free impedimetric hCG-immunosensor was constructed by using a commercial screen-printing carbon ink electrode (namely disposable electrochemical printed chip) as the ba...

Impedimetric immunoglobulin G immunosensor based on chemically modified graphenes.

Immunosensors which display high sensitivity and selectivity are of utmost importance to the biomedical field. Graphene is a material which has immense potential for the fabrication of immunosensors....

Development of an impedimetric immunosensor for the determination of 3-amino-2-oxazolidone residue in food samples.

The use of furazolidone in food animals has been banned in European Union (EU) because of its carcinogenicity and mutagenicity on human health, but its continued misuse is widespread. Therefore, there...

Impedimetric immunosensor for human serum albumin detection on a direct aldehyde-functionalized silicon nitride surface.

In this work we report the fabrication and characterization of a label-free impedimetric immunosensor based on a silicon nitride (Si(3)N(4)) surface for the specific detection of human serum albumin (...
