Aptamer based assay for sensitive detection of antibiotics in food and water samples

Antibiotics have been widely used in human medicine, aquaculture and agriculture to treat serious infectious diseases. However, overuse and misuse of antibiotics in some areas have contributed to the residues of antibiotic contaminants in water bodies and food products such as meat and dairy. This misuse has resulted in generation of super bacteria with tolerance […]

Aptamers used to speed up pesticide testing

19th December 2019

The contamination of the environment with pesticide residues has become one of the most serious problems of public health in the world, due to their wide application in agriculture industry to guarantee the crop yield and quality. This has necessitated the development of rapid, easy and highly sensitive approaches for the detection of […]

Aptamer based ‘gain of signal’ assay for small molecule detection

Detecting small molecules represents a challenge for In vitro diagnostics (IVD) due to sensitivity and specificity limits of many detection methods. Our specially designed displacement approach allows us to select aptamers that can readily be used in various IVD and point of care (POC) […]

Small molecule detection made easier using Fluorescence Anisotropy technique

9th July 2019
Traditionally, immuno-fluorescence polarization-based assays are used to detect small molecules by using antibodies and fluorescently labelled small-molecules. However, the assays do meet limitations such as complex antibody preparation, cost, and most importantly stability. Also the preparation of fluorescently labelled small molecules is challenging. The use of aptamers overcomes the limitations and brings new […]

Small molecules detection with aptamer based BLI and ELISA-like assays

2nd July 2019
Detecting and quantifying small molecule analytes can be difficult. Our specially designed displacement approach allows us to select aptamers which can directly be used in various biosensor platforms for the detection of small molecules. Binding of the aptamer to the analyte gives a ‘signal amplification’ effect which can be used as a basis for small […]
