Nanobiosensor Platforms for Detection of Food Allergens

Food allergens are very important throughout the food production and supply chain. Traditional methods have some limitations, such as high costs. Therefore, there is a need to establish a simple and easy method for detecting allergens in food. In recent years, nanotechnology has become a highly interdisciplinary field that is rapidly integrating the fields of electronics and surface science, and life sciences. It offers the opportunity to answer questions related to food safety, such as detecting allergenic proteins. The application of nanotechnology in allergen detection mainly involves nanoparticles, of which gold nanoparticles and quantum dots (QDs) are the most commonly used. However, due to these properties, new types of nanoparticles are being developed and applied, and these properties allow for faster, low-cost, sensitive, and specific detection of allergens in food.

Solutions

Nanomaterials can be integrated into chemical and biological sensors, enabling the design of fast and sensitive devices to assess freshness and detect allergens, toxins, or disease-causing contaminants. As a global allergen detection company, Lifeasible is dedicated to combining biosensors and nanoparticles to detect allergens in food. Our skilled scientists build nanobiosensor platforms for detecting food allergens with specificity, sensitivity, rapidity, low cost, and field detectability.

Lifeasible offers the following popular nanomaterials:

• Metal oxides, such as silver, gold, titanium, and carbon.
• Graphene nanotubes.
• Quantum dots.
• Magnetic nanomaterials.

Lifeasible offers three types of biosensors for the detection of allergens in food:

We have designed multiple food allergens into biosensors with a range of technical characteristics and detection limits. Lifeasible offers the detection of allergens in the following food.

• Egg albumin in eggs.
• Trace amounts of ovalbumin in wine.
• Allergens in milk and other dairy products.
• Peanuts, nuts, walnuts, etc.
• Wheat gliadin in wheat, rye, barley, and cereals.
• Parvalbumins and tropomyosins in seafood.
• Other allergens.

Based on the different potentials each nanomaterial shows for a specific allergen or class, Lifeasible is committed to providing global customers with the most appropriate nanobiosensors to detect allergens in food.
