Taggants can be detectable with specially-engineered equipment or detected with low cost detectors for field testing; Taggant technology should be extremely difficult to reverse engineer; Once integrated into an item, taggants should mark the item permanently and should not be removable
Commercially available electronic nose systems exist and are used in the food industry for quality control. Current research efforts demonstrate the introduction of the electronic nose principle into environmental monitoring and medicine both as commercial instruments as well as in consumer-grade wearable electronic devices.

Impedance spectroscopy based biosensor development has been gaining traction nowadays and many such devices / developments are found in the academia and industry. One such device, based on a 4-electrode electrochemical cell, using a nanoporous alumina membrane, has been shown to detect low concentrations of human alpha thrombin in presence of ...
S. cerevisiae septins revealed with fluorescent microscopy utilizing fluorescent labeling. In molecular biology and biotechnology, a fluorescent tag, also known as a fluorescent label or fluorescent probe, is a molecule that is attached chemically to aid in the detection of a biomolecule such as a protein, antibody, or amino acid.
A fiducial marker or fiducial is an object placed in the field of view of an image for use as a point of reference or a measure. It may be either something placed into or on the imaging subject, or a mark or set of marks in the reticle of an optical instrument.
In 2008, 3% of the tested samples contained detectable amounts of GMOs. [3] In 2012, 12% of the samples analysed contained detectable amounts of GMOs (including 2.4% of GMOs forbidden in Switzerland). [3] Except one, all the samples tested contained less than 0.9% of GMOs; which is the threshold that impose labelling indicating the presence of ...
In a sweeping two-year investigation, The Associated Press found goods linked to U.S. prisoners wind up in the supply chains of a dizzying array of products from Frosted Flakes cereal and Ball ...
An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
