The control of chemical residues is essential in honey’s marketing to ensure consumer safety. Equipments available in the market reach the required limit of detection (LOD) (e.g Liquid Cromatography -HPLC) but are not suitable for in-situ implantation in honey packaging industry because they are more expensive and time-consuming and require highly qualified staff. Other approaches available in the market, although faster and without the need of qualified staff, do not reach the required LODs.
However, piezoelectric immunosensors like HFF-AWS based on High Fundamental Frequency Quartz Crystal Microbalance, combined with an antigen-antibody recognition process, are a good alternative or complementary technology for chemical residues control in food. Why? Let us tell you only 5 strong reasons to justify it:
- Lower cost
You will only need a very affordable equipment such as AWS platform
- Suitable for in-situ implantation in hone packaging industry
The equipment is easily adapted to an industrial process
- Less sample/reagent consumption
You will need less than 3 ul sample
- Label-free and real time transduction
- LOD improved

AWSensors showed its work entitled “HFF-QCM immunosensor for fast and sensitive detection of DDT in Honey” in the Third International Congress on Quality and Food Safe Acofesal 2015 held in Valencia. We are pleased to share it with you. You can look it up HERE.
