Anti-microbial drugs are widely employed for the treatment and cure of diseases in animals, promotion of animal growth, and feed efficiency. However, the scientific literature has indicated the possible presence of antimicrobial drug residues in animal-derived food, making it one of the key public concerns for food safety. Therefore, it is highly desirable to design fast and accurate methodologies to monitor antimicrobial drug residues in animal-derived food. Legislation is in place in many countries to ensure antimicrobial drug residue quantities are less than the maximum residue limits (MRL) defined on the basis of food safety. In this context, the recent years have witnessed a special interest in the field of electrochemical biosensors for food safety, based on their unique analytical features. This review article is focused on the recent progress in the domain of electrochemical biosensors to monitor antimicrobial drug residues in animal-derived food.

“…As they also exhibit good biocompatibility toward biologically active molecules, nano-SiO 2 particles represent excellent carriers for the immobilization of proteins and enzymes in electrochemical biosensors [131]. For example, Hong et al [132] prepared ferrocene-coated SiO 2 nanoparticles using oil-in-water technology to form stable, homogeneous, biocompatible, and highly surface active interfaces to effectively immobilize the antibodies in a no-reagent electrochemical immunosensor.…”

Electrochemical immunosensors resulting from a combination of the traditional immunoassay approach with modern biosensors and electrochemical analysis constitute a current research hotspot. They exhibit both the high selectivity characteristics of immunoassays and the high sensitivity of electrochemical analysis, along with other merits such as small volume, convenience, low cost, simple preparation, and real-time on-line detection, and have been widely used in the fields of environmental monitoring, medical clinical trials and food analysis. Notably, the rapid development of nanotechnology and the wide application of nanomaterials have provided new opportunities for the development of high-performance electrochemical immunosensors. Various nanomaterials with different properties can effectively solve issues such as the immobilization of biological recognition molecules, enrichment and concentration of trace analytes, and signal detection and amplification to further enhance the stability and sensitivity of the electrochemical immunoassay procedure. This review introduces the working principles and development of electrochemical immunosensors based on different signals, along with new achievements and progress related to electrochemical immunosensors in various fields. The importance of various types of nanomaterials for improving the performance of electrochemical immunosensor is also reviewed to provide a theoretical basis and guidance for the further development and application of nanomaterials in electrochemical immunosensors.

“…This new type of label for immunosensors may provide many potential applications for the detection of the growth hormone in animal derived food. Another immunosensor application in food technology was carried out by Liu et al (2011). A facile and simple electrochemical immunoassay for ultrasensitive determination of streptomycin residues (STR) in food was designed.…”

Bernardos A., Kouřimská L. (2013): Applications of mesoporous silica materials in food -a review. Czech J. Food Sci., 31: 99-107.Mesoporous silica materials have been developed for some applications in the health field. These solids are used for the controlled release of bioactive molecules, as catalysts in the synthesis of essential nutrients, as sensors to detect unhealthy products etc., with many applications in food technologies. By combining mesoporous silica materials with food, we can create healthier products, the products that improve our quality of life. The development of mesoporous materials applied to food could result in protecting bioactive molecules during their passage though the digestive system. For this reason, the controlled release of bioactive molecules is a very interesting topic for the discipline of food technology. The use of mesoporous silica supports as catalysts in the synthesis of nutrients and as sensors for the detection of unhealthy products, essential in food, is in great demand industrially for the manufacture of functional foods and films for food and industrial packaging. This review shows some examples of silica materials and their applications in food.
