A method for colorimetric detection of cholesterol in a sample is disclosed. The method includes adding beta-cyclodextrin and cholesterol to a phenolphthalein indicator solution in the presence of a phosphate buffer solution to create a solution medium and quantifying the cholesterol as a function of a complexed beta-cyclodextrin in the solution medium.

The present invention relates to methods and compositions to remove or reduce biotin interference from certain assays.

An electrochemical sensor and a method for detecting pathogenic metabolites such as viral or bacterial metabolites are presented. The electrochemical sensor includes a first electrode modified with oligosaccharide molecules. In the detection method, a first electrode modified with oligosaccharide molecules is provided and a sample is applied on the first electrode. An electrochemical response is then measured using the first electrode to detect pathogenic metabolites in the sample.
