Analytical Insights at the Point-Of-Need By Immunoanalytical Technologies
- A vast number of emerging pollutants is being detected in the environment. Another lingering problem are health-threatening contaminants, such as mycotoxins, that deteriorate food and feed. Analytical methods, suitable for trace analysis, are needed that are desirably also fast, inexpensive and, if possible, robust, and portable. Immunoanalytical, i.e., anti-body-based technologies, which are available in a broad range of formats, can be profitably used here to analyze for the distribution and the concentration trends of contaminants. Some of these formats are single-analyte but high-throughput methods. To use them wisely, indicator substances or sum parameters must be established to be used in screening approaches. Other methods are suitable to be performed on portable in-strumentation in the field (on-site), more precisely at the point-of-need. Furthermore, there are array technologies that allow for parallel analysis of several analytes of interest (multiplexing).

The talk reports on methods and data for compounds con-sidered as anthropogenic contamination markers (the antiepileptic carbamazepine, the analgesic diclofenac, the anti-histaminic cetirizine, the steroid hormone estrone, the antimicrobial amoxicillin, the stimulants caffeine and cocaine, the endocrine disruptor bisphenol A, and a bile acid). Some work on mycotoxins (ochratoxin A and ergot alkaloids) is also presented. It is demonstrated that antibody-based technolo-gies have a huge potential to gain analytical insights at the point-of-need.…
