background
● Food safety assurance is of great importance under the globalization of distribution in recent years.
● For example, the number of food allergy patients has continuously increased year by year.
● Simple technique for detecting contaminants (i.e. food allergens) in foods is awaited.

summary
● Semiconductor-based biosensors can detect a small amount of target molecules in foods.
● We have developed a biosensing technology to determine the presence of anaphylactogenic food allergens.
