Special Issue Information
Dear Colleagues,
Allergen analysis involves the identification, quantification, and characterization of allergenic substances in various samples, such as foods, environmental samples, and clinical samples. The goal is to determine the presence and concentration of specific allergens, which are substances that can trigger allergic reactions in sensitive individuals. Allergen analysis plays a crucial role in food safety, environmental monitoring, and understanding allergic diseases. Here are some key aspects of allergen analysis:
- Detection Methods: Various methods are used to detect allergens, including molecular, immunological, and biochemical techniques. These methods aim to identify allergenic proteins or DNA sequences associated with allergens.
- Molecular Techniques: Molecular methods, such as PCR and real-time PCR, target specific DNA sequences to detect allergens. These methods are particularly useful for identifying allergens in processed foods where protein structure might be altered.
- Immunological Assays: Immunological techniques, such as enzyme-linked immunosorbent assays (ELISA) and lateral flow assays, use antibodies to detect allergenic proteins. These methods are widely used due to their sensitivity and specificity.
- Mass Spectrometry: Mass spectrometry is a powerful tool for allergen identification and quantification. It can provide information about the structure and sequence of allergenic proteins in complex samples.
- Microarray Technology: Allergen microarrays enable the simultaneous detection of multiple allergens in a single assay. These arrays can profile allergen-specific IgE antibodies in patient samples, aiding in diagnosis and treatment.
- Biosensors: Biosensors utilize biological molecules to recognize and quantify allergens, producing a measurable signal. Biosensors are often portable and suitable for on-site allergen detection.
- Nanotechnology: Nanomaterials are employed to enhance the sensitivity and selectivity of allergen detection methods. Nanoparticles can be functionalized to bind specifically to allergenic proteins, amplifying the detection signal.
- Bioinformatics: Advanced computational tools are used to analyze large datasets generated by allergen analysis methods. Bioinformatics helps predict allergenic epitopes, assess cross-reactivity, and enhance the understanding of allergen structures.
- Point-of-Care Testing: Mobile apps and portable devices enable individuals to test for allergens in their surroundings or foods, offering rapid results and empowering allergic individuals to make informed choices.
- Regulatory Compliance: Allergen analysis is essential for regulatory compliance in the food industry. Labeling laws require accurate identification and declaration of allergenic ingredients in packaged foods.
Advances in allergen analysis techniques continue to emerge, contributing to improved accuracy, sensitivity, and speed of detection. Researchers and industries strive to develop methods that can better accommodate complex matrices, such as processed foods, and enhance the safety of individuals with allergies.
It is the aim of this Special Issue to showcase the recent advances in analytical methodologies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
Benefits of Publishing in a Special Issue
