Summary of the technology
Fast, efficient and accurate method for the quantification of alkylphenols (APs). These sensors are based on a network of single-walled carbon nanotubes functionalized with a highly specific anti-AP antibody, which is at the core of the AP quantification reaction. This quantification is determined as a function of the changes in the electrical current, which varied according not only to the presence of absence of these com-pounds, but also in proportion to their concentration.
Alkylphenols are used in plastics production and in the synthesis of non-ionic surfactants widely used as components of detergents, paints, herbicides, humectant agents, cosmetics, pesticides and many other domestic, industrial and agricultural products. AP and their derivatives are known endocrine disruptors with estrogenic action, which associated to its ubiquity, entail constant analysis and monitoring.
In general, the techniques currently used for APs quantification are based in methods that require extensive sample preparation, are very expensive and utilize specific equipment (HPLC, LC-MS and GC-MS). The proposed sensors allow replacing those techniques, since they are fast, efficient and accurate and allow a much more widespread use since they are very low cost and easy to use.
REDUCED SAMPLE VOLUME: less than 1ml.
NO SAMPLE PREPARATION REQUIREMENTS
IN SITU ANALYSIS: potentially, there is no need of laboratorial analysis.
MUCH FASER: the analysis takes only a few minutes.
IMPROVED OR EQUAL DETECTION/QUANTIFICATION LIMITS: compared to the current techniques.
ADAPTABLE TO OTHER COMPOUNDS
This technology has several applications:
ENVIRONMENTAL (alkylphenols monitoring)
INDUSTRIAL (quality control, e.g. liquid food products)
The technology may be adapted to other compounds as well, widening its applications into other sectors.
TRL 4: tested at laboratorial level for detection and quantification of alkylphenols.
Available for presentation.
Researchers of Centre for Environmental and Marine Studies (CESAM) of the University of Aveiro, of INESC-MN (Lisbon) and of the University of Sfax, Tunisia.
Development of new formulations and/or applications.
The University of Aveiro seeks partners in environmental and/or pharmaceutical sectors, as well as companies operating in the area of (bio)sensors.
Based on the biosensor’s efficiency and sensitivity, it is of particular interest to partners working in the fields of food industry, but also for potential partners undertaking efforts in biology and environmental monitoring.
