Electrospining Machine: Electrospun Nanofbers sensors, how to accurately and rapidly detect food contaminants?

Background

Food contamination is a major global health risk and a major challenge for the food industry. It can come from biological contaminants such as pathogens, parasites and viruses, as well as chemical contaminants such as heavy metals, pesticides, drugs and hormones. There may also be naturally occurring harmful chemicals. Therefore, the development of sensing platforms has become crucial for accurate and rapid identification of contaminants and hazards in food.

Electrospun nanofibres (NFs) offer a promising solution due to their unique 3D structure, large specific surface area and ease of preparation. In addition, NFs exhibit excellent biocompatibility, degradability, and adaptability, making monitoring more convenient and environmentally friendly. These properties also significantly reduce the process of contaminant detection. NF-based sensors are capable of detecting a wide range of biological, chemical and physical hazards.
